扭剪扳手主要是终紧扭剪型高强螺栓的，它的目的就是把扭剪型高强螺栓的梅花头打断即可。工作时将扳手头对准螺栓头，扣动开关即可开始工作，几秒后，螺栓梅花头将被扭断，然后抽出扳手扣动扳机将梅花头弹出，即结束工作。
The torque wrench is mainly used for final tightening of torque shear type high-strength bolts, and its purpose is to break the Torx head of the torque shear type high-strength bolt. When working, align the wrench head with the bolt head, and press the switch to start working. After a few seconds, the bolt ring head will be twisted off. Then, pull out the wrench and pull the trigger to eject the ring head, which ends the work.
电动扳手主要应用于钢结构安装行业，专门安装钢结构高强螺栓，高强度螺栓是用来连接钢结构接点的，通常是用螺栓群的方式出现。高强螺栓可分为扭剪型和大六角型两种，国标扭剪型高强螺栓为M16、M20、M22、M24四种，非国标的M27、M30两种；国标大六角高强螺栓为M16、M20、M22、M24、M27、M30等几种。一般的对于高强螺栓的紧固都要先初紧再终紧，而且每步都需要有严格的扭矩要求。大六角高强螺栓的初紧和终紧都必须使用定扭矩扳手.故各种电动扳手就是为各种紧固需要而来的。
Electric wrenches are mainly used in the steel structure installation industry to install high-strength bolts for steel structures. High-strength bolts are used to connect steel structure joints, usually in the form of bolt groups. High strength bolts can be divided into two types: torsional shear type and large hexagon type. The national standard torsional shear type high strength bolts include M16, M20, M22, and M24, while the non national standard bolts include M27, and M30; The national standard large hexagon high-strength bolts include M16, M20, M22, M24, M27, M30, etc. Generally, the tightening of high-strength bolts requires initial tightening before final tightening, and each step requires strict torque requirements. A constant torque wrench must be used for initial and final tightening of large hexagon high-strength bolts. Therefore, various electric wrenches are designed for various tightening needs.
