先說(shuō)下電動(dòng)扳手的分類，其是以電源或電池為動(dòng)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(zhuǎn)角扳手、角向扳手。那么有的朋友會(huì)問(wèn)了五種電動(dòng)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(dòng)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(dòng)扳手：主要是初緊螺栓的，它的操作簡(jiǎn)單，就是對(duì)準(zhǔn)螺栓扳動(dòng)電源開(kāi)關(guān)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(dòng)扭剪扳手：主要是終緊扭剪型高度螺栓的，它的使用就是對(duì)準(zhǔn)螺栓扳動(dòng)電源開(kāi)關(guān)，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(dòng)定扭矩扳手：既可初緊又可終緊，它的使用是先調(diào)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(dòng)轉(zhuǎn)角扳手：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。
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(dòng)角向扳手：是一種專門緊固鋼架夾角部位螺栓的電動(dòng)扳手，它的使用和電動(dòng)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
