As the name suggests, the electric wrench is a necessary tool for tightening screws. It can help you install and remove bolts and nuts, and accurately control the tightening torque. Under the fixed torque of the bolt, when the wrench reaches a certain torque, the rod head part of the bolt can be cut off. The fixed torque V-notch of the bolt ensures the torque accuracy and axial tension of the bolt. The disassembly torque is large, which is more reliable than manual safety. Convenient, beautiful, practical and portable. It is widely used in the construction of steel structure bridge, workshop, power generation equipment and other facilities.

电动扳手是一种用于高强度螺栓端部紧固的工具，一般有电动扳手和手动扳手，其中电动扳手较为常见。

Electric wrench is a kind of tool used to fasten the end of high-strength bolt. There are generally electric wrench and manual wrench, among which electric wrench is more common.

扭力、剪力扳手的应用:扭力、剪力高强度螺栓的初始紧固可采用冲击电动扳手或固定力矩扳手，扭力、剪力扳手的紧固必须采用扭力、剪力扳手。

Application of torque and shear wrench: impact electric wrench or fixed torque wrench can be used for the initial tightening of high strength bolts, and torque and shear wrench must be used for the tightening of torque and shear wrench.

扭剪扳手的使用:扭剪扳手主要是端部剪切的高强螺栓，其目的是剪切扭剪的高强螺栓可以断裂。工作时，将扳手头放在螺栓头上，拉动开关开始工作，几秒钟后，螺栓头将被扭紧，然后拔出扳手，扣动扳机，使棒子头部弹出，即工作结束。

Use of torsional shear wrench: torsional shear wrench is mainly used for high-strength bolts sheared at the end. Its purpose is to shear the high-strength bolts sheared can be broken. When working, put the wrench head on the bolt head and pull the switch to start working. After a few seconds, the bolt head will be tightened. Then pull out the wrench and pull the trigger to make the rod head pop out, that is the end of the work.

特点:操作方便，省时省力，方便

Features: easy to operate, time-saving, safe and convenient
