The wrench is mainly used to tighten the bolt. Its use is very simple, that is, to align the bolt and pull the power switch. The electric wrench is mainly used to tighten the high-strength bolt. Its use is to align the bolt and pull the power switch until the quincunx head of the high-strength bolt is broken. The wrench can be used for both initial tightening and final tightening. It is used to adjust the torque first and then tighten the bolt.

扭剪扳手主要也属于定扭矩扳手的一种,它的使用是先调节旋转度数,再紧固螺栓。电动角向扳手是一种专门紧固钢架夹角部位螺栓的必威西汉姆联官网g1线路,它的使用和电动扭剪扳手原理一样

Torsional shear wrench is also a kind of constant torque wrench. Its use is to adjust the degree of rotation first, and then tighten the bolt. The electric angle wrench is a kind of electric wrench specially used to fasten the bolts in the angle part of the steel frame. Its use principle is the same as that of the electric torsional shear wrench

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。

Torsional shear wrench is mainly used to tighten torsional shear high-strength bolt. Its purpose is to break the quincunx head of torsional shear high-strength bolt. When working, align the wrench head with the bolt head, and pull the switch to start working. After a few seconds, the quincunx head of the bolt will be broken, and then pull out the wrench to pull the trigger to eject the quincunx head, which is the end of the work.

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.故各种必威西汉姆联官网g1线路就是为各种紧固需要而来的

Generally, the high-strength bolts should be tightened first and then finally, and each step needs to have strict torque requirements. Constant torque wrench must be used for the initial tightening and final tightening of large hexagon high strength bolts. Therefore, all kinds of electric wrench are for all kinds of tightening needs
