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.

扭剪扳手主要也屬于定扭矩扳手的一種,它的使用是先調(diào)節(jié)旋轉(zhuǎn)度數(shù),再緊固螺栓。電動角向扳手是一種專門緊固鋼架夾角部位螺栓的電動扳手,它的使用和電動扭剪扳手原理一樣

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。

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

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
