The electric torque wrench is mainly used to tighten high-strength bolts of torque shear, with the purpose of breaking the plum blossom head of high-strength bolts of torque shear. When working, align the wrench head with the bolt head and pull the switch to start working. After a few seconds, the plum blossom head of the bolt will break, and then pull out the wrench and pull the trigger to eject the plum blossom head, 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。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。

Electric torsion shear wrenches are mainly used in the steel structure installation industry, specifically 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 two types: torsional shear type and large hexagonal type. The national standard torsion shear type high-strength bolts are M16, M20, M22, and M24, while non national standards are M27 and M30; The national standard large hexagonal high-strength bolts are M16, M20, M22, M24, M27, M30, etc. Generally, high-strength bolts should be tightened first and then tightened, with strict torque requirements for each step. So, various electric shear wrenches are designed to meet various tightening needs.

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, which can help you install and remove bolts and nuts, and more accurately control the tightening torque. 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 torque accuracy and axial tension, with high disassembly torque, making it 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。

The characteristics of electric torsion wrench: 1. Its service life is very long. 2. The handle and shell materials have good heat dissipation. 3. High power. 4. Strong impact resistance. 5. High cost-effectiveness for purchase and use.

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 initial tightening of high-strength bolts, and electric torque wrench must be used for final tightening. Therefore, electric torque wrench is a special wrench for final tightening of high-strength bolts.
