Product Description Product DescriptionDefinition and Basic PrinciplesAn electric wrench is a handheld tool that uses electric energy to tighten and loosen various bolts and nuts. Its basic principle is to transmit power to the wrench head through the rotational motion of the motor and transmission devices such as the reduction mechanism, thereby driving the bolt or nut to rotate.For example, when the motor is started, the high-speed rotation of the motor shaft is reduced by gear sets and other reduction devices, increasing the torque and allowing the wrench head to output sufficient force to operate bolts and nuts.Structural compositionMotor part: It is the power source of the electric wrench. Generally, DC motors or AC motors are used. DC motors are commonly used for small portable electric wrenches because they can be powered by batteries and are convenient to use in places without power sockets; AC motors are suitable for electric wrenches with high power and working in stable power environments.Transmission mechanism: including gear sets, clutches, etc. The gear set mainly plays a role in reducing speed and increasing torque, converting the high-speed low torque output of the motor into a low-speed high torque output suitable for tightening bolts. The clutch can automatically disengage when the set torque is reached, preventing excessive tightening and protecting the bolts and connected components.Wrench head: There are different sizes and shapes to accommodate various specifications of bolts and nuts. Common types include hexagonal heads, square heads, socket heads, etc., and sockets of different specifications can be replaced to meet different work needs.Control section: includes switches and torque adjustment devices. The switch is used to control the start and stop of the electric wrench, and the torque adjustment device can set the tightening torque according to the actual working requirements.Main functional featuresEfficient and labor-saving: Compared to manual wrenches, electric wrenches can quickly tighten or loosen bolts and nuts, greatly improving work efficiency. For example, on an automobile assembly line, using an electric wrench can complete a large amount of bolt tightening work in a short period of time, reducing the labor intensity of workers.Accurate torque control: Through the torque adjustment device, the tightening torque can be precisely controlled. In some situations where bolt tightening force is strictly required, such as bridge construction, precision mechanical assembly, etc., it can be ensured that each bolt is tightened according to the specified torque, ensuring the quality of the project and the reliability of the equipment.Wide applicability: It can be used for bolts and nuts made of various materials, including steel, aluminum alloy, etc., and can adapt to different working environments, such as factory workshops, construction sites, automobile repair shops, etc.classificationClassified by torque control method:There is a torque control type: This type of electric wrench can precisely control the output torque through an internal torque adjustment mechanism. When the set torque is reached, the electric wrench will automatically stop tightening or send a warning signal, which is suitable for occasions with strict requirements for bolt tightening force.Non torque control type: mainly used in situations where torque accuracy is not required, such as simple disassembly work or bolt tightening with less strict tightening force requirements, and its price is relatively low.Classified by power type:AC electric wrench: It needs to be connected to an AC power outlet to work, with high power and suitable for use in fixed workplaces with stable power sources, such as large equipment assembly workshops in factories.DC electric wrench: usually powered by batteries, it has good portability and can be used in places without AC power, such as outdoor construction, car maintenance and rescue scenarios.application area Automotive manufacturing and maintenance: The tightening of numerous bolts used to assemble components such as engines and chassis during the production process of automobiles. During car maintenance, it is convenient for maintenance personnel to quickly disassemble and install bolts for tires, engine components, etc.Construction industry: used for bolted connections in the installation of steel structures, scaffolding, formwork, etc., to improve construction speed and quality.Mechanical manufacturing and assembly: Ensuring that bolts are tightened according to design requirements during the assembly process of various mechanical equipment is an important tool for ensuring equipment accuracy and reliability.Home appliance manufacturing: For example, in the assembly process of household appliances such as refrigerators and washing machines, electric wrenches can efficiently complete the tightening of screws.Detailed Photos Product ParametersProduct NameBrushless Lithium ion WrenchTypelithium batteryno-load speed0-2600r/minimpact frequency0-3500ipmLoad torque450N.MNet weight1.1kgPackaging & ShippingCompany ProfileHunan Zhiben Electric Power Technology Co., Ltd., as a senior leader in the power industry, has been working diligently in this field for ten years.

Use a clean soft cloth to wipe off dust, oil stains, and other stains on the surface of the tool. For gaps, a small brush can be used to clean them. If there is stubborn dirt, dip a small amount of mild cleaning agent and gently wipe it, but avoid the cleaning agent from entering key components such as the motor. For tools like electric drills and chainsaws that are prone to accumulating wood chips or metal debris, it is necessary to clean the chip groove in a timely manner to ensure that the debris does not affect the normal operation of the tool.Q2: How to maintain the battery of battery powered electric tools?A: For lithium batteries, try to avoid overcharging and overdischarging as much as possible. After each use of the tool, charge it promptly and do not wait for the battery to run out before charging; When not using tools for a long time, it is recommended to charge the battery to around 50-60% and store it, and perform a charge discharge cycle every few months to maintain battery activity. Nickel cadmium batteries and nickel hydrogen batteries should be fully charged before the first use, and fully discharged and recharged after use to calibrate the battery capacity. In addition, batteries should be stored in a cool and dry environment, avoiding high temperatures and humidity to prevent damage to battery performance.Q3: Do electric tools require special maintenance for their motors?A: In general, it is not necessary to frequently disassemble and maintain the motor. In daily use, keep the tools well ventilated, avoid motor overheating, and prevent foreign objects from entering the interior of the motor. If the motor produces abnormal noise, severe heating, or insufficient power, it should be stopped from use and professional maintenance personnel should be contacted for inspection. Do not disassemble the motor by yourself to avoid damaging the internal precision structure.FAQ 2: Key points for purchasing electric toolsQ1: How to choose the appropriate type of electric tool based on needs?A: If mainly used for screwing screws, an electric screwdriver or a multifunctional electric drill with screwing function is more suitable. Electric screwdrivers are usually lighter and suitable for fine operation; If dealing with the tightening of large bolts, such as in the fields of construction and automotive maintenance, electric wrenches are the preferred choice as they can provide greater torque. To cut materials such as wood and metal, electric drills and chainsaws are selected according to different materials and cutting requirements. For example, curved saws are suitable for cutting complex shaped wood, while angle grinders are commonly used for metal polishing and cutting.Q2: What performance indicators of electric tools should be valued?A: Firstly, power. The higher the power, the stronger the power of the general tool, and the faster the working speed. However, energy consumption and portability should also be considered. Torque is crucial for tightening tools such as electric wrenches, ensuring that they can meet the tightening requirements of bolts during operation. In terms of speed, the speed of tools such as electric drills and chainsaws determines the efficiency of cutting and drilling, and different materials and work scenarios have different suitable speed ranges. In addition, the durability of the tool, such as the material of the outer shell, the quality of the internal mechanical structure, and whether it has overload protection and other safety functions, cannot be ignored.Q3: Is brand important when purchasing power tools?A: Brand is important to a certain extent. Famous brands usually have stricter quality control systems, high product reliability, and more guaranteed after-sales service. They have undergone long-term market testing and mature technology, often performing well in areas such as battery life and torque precision control. However, some niche brands may also launch products with high cost-effectiveness, so when making a purchase, it is advisable to consider one's own budget, performance requirements for tools, comprehensively evaluate brand factors, and view user reviews and professional evaluations to assist decision-making.FAQ 3: Precautions for Safe Use of Electric ToolsQ1: What preparations need to be made before using electric tools?A: Firstly, check the appearance of the tool for any damage, such as cracked casing or damaged power cord. If there are any issues, do not use it. For new tools or tools that have not been used for a long time, it is necessary to refer to the instruction manual, familiarize oneself with the operating methods and functional characteristics. When connecting to the power supply, ensure that the voltage meets the requirements of the tool, and check the battery level and installation of the DC tool for correctness. Also, it is necessary to wear personal protective equipment such as goggles, gloves, and safety helmets (in environments with a risk of falling objects from high altitude).Q2: What are the safety points during the use of electric tools?A: When using, keep your body stable, stand firmly with both feet, grip the tool handle tightly, and prevent it from slipping off due to tool vibration or accidental activation. Overloading is strictly prohibited. Operate according to the working range specified in the tool manual, such as not forcefully drilling large diameter holes with a low-power electric drill. If multiple people are working at the same time, they should maintain a safe distance to avoid mutual interference and accidents. In humid environments or places with special requirements for electrical insulation, electric tools with corresponding protection levels should be used, and the insulation performance of the tools should be regularly checked.Q3: What should I do when an electric tool malfunctions?A: Once the electric tool malfunctions, such as smoking, odor, abnormal vibration, etc., it should be stopped immediately and the power plug (or battery) should be unplugged. Do not attempt to repair complex faults on your own, especially those involving key parts such as motors and circuits. Instead, contact professional maintenance personnel or the after-sales service department of the tool manufacturer, describe the fault symptoms in detail to them, and wait for professional repairs. Do not use the tool again until the fault has been resolved to avoid greater danger.
