先说下电动扳手的分类，其是以电源或电池为动力的扳手，它是一种拧紧高度度螺栓的工具，主要分为冲击扳手、扭剪扳手、定扭矩扳手、转角扳手、角向扳手。那么有的朋友会问了五种电动扳手的区别在于哪里！
First of all, let's talk about the classification of electric wrench. It is a wrench powered by power supply or battery. It is a tool for tightening height bolts. It is mainly divided into impact wrench, torsion shear wrench, constant torque wrench, angle wrench and angle wrench. Then some friends will ask what is the difference between the five kinds of electric wrenches!
电动扳手几种类型的区别如下：
The differences of several types of electric wrenches are as follows:
1.冲击电动扳手：主要是初紧螺栓的，它的操作简单，就是对准螺栓扳动电源开关就行。
1. Impact electric wrench: it is mainly used to initially tighten the bolt. Its operation is simple, that is, align the bolt and pull the power switch.
2.电动扭剪扳手：主要是终紧扭剪型高度螺栓的，它的使用就是对准螺栓扳动电源开关，直到把扭剪型高度螺栓的梅花头打断为止。
2. Electric torsion shear wrench: it is mainly used to finally tighten the torsion shear height bolt. Its use is to align the bolt and pull the power switch until the plum blossom head of the torsion shear height bolt is broken.
3.电动定扭矩扳手：既可初紧又可终紧，它的使用是先调节扭矩，再紧固螺栓。
3. Electric constant torque wrench: it can be tightened initially and finally. Its use is to adjust the torque first and then tighten the bolts.
4.电动转角扳手：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。
4. Electric angle wrench: it mainly belongs to a kind of constant torque wrench. Its use is to adjust the rotation degree first, and then tighten the bolt.
5.电动角向扳手：是一种专门紧固钢架夹角部位螺栓的电动扳手，它的使用和电动扭剪扳手原理一样
5. Electric angle wrench: it is an electric wrench specially used to fasten the bolts at the included angle of the steel frame. Its use principle is the same as that of the electric torsion shear wrench
