先說下電動扳手的分類，其是以電源或電池為動力的扳手，它是一種擰緊高度度螺栓的工具，主要分為沖擊扳手、扭剪扳手、定扭矩扳手、轉角扳手、角向扳手。那么有的朋友會問了五種電動扳手的區(qū)別在于哪里！
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!
電動扳手幾種類型的區(qū)別如下：
The differences of several types of electric wrenches are as follows:
1.沖擊電動扳手：主要是初緊螺栓的，它的操作簡單，就是對準螺栓扳動電源開關就行。
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.電動扭剪扳手：主要是終緊扭剪型高度螺栓的，它的使用就是對準螺栓扳動電源開關，直到把扭剪型高度螺栓的梅花頭打斷為止。
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.電動定扭矩扳手：既可初緊又可終緊，它的使用是先調節(jié)扭矩，再緊固螺栓。
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.電動轉角扳手：主要也屬于定扭矩扳手的一種，它的使用是先調節(jié)旋轉度數，再緊固螺栓。
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.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
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
