The electric torque wrench is mainly used to fasten the torque shear high-strength bolts, and its purpose is to break the Torx head of the torque shear high-strength bolts. When working, align the wrench head with the bolt head and pull the switch to start working. After a few seconds, the ring head of the bolt will break, and then pull out the wrench and pull the trigger to pop the ring head out, which is the end of the work.

电动扭剪扳手主要用于钢结构安装行业，专门用于钢结构高强螺栓的安装。高强度螺栓用于连接钢结构节点，通常采用螺栓组的形式。高强度螺栓可分为扭剪型和大六角型两种。

The electric torsion wrench is mainly used in the steel structure installation industry, especially for the installation of high-strength bolts in steel structures. High-strength bolts are used to connect steel structure nodes, usually in the form of bolt groups. High-strength bolts can be divided into torsion shear type and large hexagon type.

国标扭剪型高强度螺栓为M16、M20、M22、M24，非国标为M27、M30；国标大六角高强度螺栓为M16、M20、M22、M24、M27、M30等，一般高强度螺栓应先拧紧后拧紧，每一步都有严格的扭矩要求。所以，各种电动扭剪扳手都是为了满足各种拧紧的需要。

National standard torsional shear type high-strength bolts are M16, M20, M22 and M24, and non-national standard bolts are M27 and M30; The national standard large hexagon high-strength bolts are M16, M20, M22, M24, M27, M30, etc. Generally, high-strength bolts should be tightened first and then tightened. Each step has strict torque requirements. Therefore, all kinds of electric torque wrench are designed to meet various tightening requirements.

电动扭剪扳手是拧紧螺栓的工具，它可以帮助您安装和拆卸螺栓和螺母，并更准确地控制拧紧力矩。当扳手达到一定扭矩时，螺栓的梅花头即可被切断。螺栓的V形切口保证了扭矩精度和轴向拉力，拆装扭矩大，比手动操作更可靠。

Electric torque wrench is a tool for tightening bolts. It can help you install and remove bolts and nuts, and control the tightening torque more accurately. When the wrench reaches a certain torque, the ring head of the bolt can be cut off. The V-shaped notch of the bolt ensures the torque accuracy and axial tension, and the disassembly torque is large, which is safer and more reliable than manual operation.

电动扭剪扳手的特点：1、它的使用寿命很长。2、手柄和外壳材料的散热性好。3、功率很大。4、抗冲击性较强。5、购买使用的性价比高。

Features of the electric torsion wrench: 1. Its service life is very long. 2. Handle and shell materials have good heat dissipation. 3. The power is very high. 4. Strong impact resistance. 5. The purchase price is high.

电动扭剪扳手的应用：扭剪高强螺栓的初紧可采用冲击式电动扳手或恒扭矩扳手，终紧必须采用电动扭剪扳手，故电动扭剪扳手是扭剪高强螺栓终紧的专用扳手。

Application of electric torque wrench: impact electric wrench or constant torque wrench can be used for the initial tightening of high-strength bolts, and electric torque wrench must be used for final tightening, so electric torque wrench is a special wrench for final tightening of high-strength bolts.
