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.

電動扭剪扳手主要用于鋼結(jié)構(gòu)安裝行業(yè)，專門用于鋼結(jié)構(gòu)高強螺栓的安裝。高強度螺栓用于連接鋼結(jié)構(gòu)節(jié)點，通常采用螺栓組的形式。高強度螺栓可分為扭剪型和大六角型兩種。

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.

國標扭剪型高強度螺栓為M16、M20、M22、M24，非國標為M27、M30；國標大六角高強度螺栓為M16、M20、M22、M24、M27、M30等，一般高強度螺栓應先擰緊后擰緊，每一步都有嚴格的扭矩要求。所以，各種電動扭剪扳手都是為了滿足各種擰緊的需要。

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.

電動扭剪扳手是擰緊螺栓的工具，它可以幫助您安裝和拆卸螺栓和螺母，并更準確地控制擰緊力矩。當扳手達到一定扭矩時，螺栓的梅花頭即可被切斷。螺栓的V形切口保證了扭矩精度和軸向拉力，拆裝扭矩大，比手動操作更可靠。

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.

電動扭剪扳手的特點：1、它的使用壽命很長。2、手柄和外殼材料的散熱性好。3、功率很大。4、抗沖擊性較強。5、購買使用的性價比高。

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.

電動扭剪扳手的應用：扭剪高強螺栓的初緊可采用沖擊式電動扳手或恒扭矩扳手，終緊必須采用電動扭剪扳手，故電動扭剪扳手是扭剪高強螺栓終緊的專用扳手。

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.
