扭剪扳手主要是終緊扭剪型高強螺栓的，它的目的就是把扭剪型高強螺栓的梅花頭打斷即可。工作時將扳手頭對準螺栓頭，扣動開關(guān)即可開始工作，幾秒后，螺栓梅花頭將被扭斷，然后抽出扳手扣動扳機將梅花頭彈出，即結(jié)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.
電動扳手主要應用于鋼結(jié)構(gòu)安裝行業(yè)，專門安裝鋼結(jié)構(gòu)高強螺栓，高強度螺栓是用來連接鋼結(jié)構(gòu)接點的，通常是用螺栓群的方式出現(xiàn)。高強螺栓可分為扭剪型和大六角型兩種，國標扭剪型高強螺栓為M16、M20、M22、M24四種，非國標的M27、M30兩種；國標大六角高強螺栓為M16、M20、M22、M24、M27、M30等幾種。一般的對于高強螺栓的緊固都要先初緊再終緊，而且每步都需要有嚴格的扭矩要求。大六角高強螺栓的初緊和終緊都必須使用定扭矩扳手.故各種電動扳手就是為各種緊固需要而來的。
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.
