電動扳手是以電源或電池為動力的扳手，它是一種擰緊高強度螺栓的工具，主要分為沖擊電動扳手、電動扭剪扳手、電動定扭矩扳手、電動轉(zhuǎn)角扳手、電動角向扳手。五種電動扳手有哪些區(qū)別呢?萬中小編今天給大家介紹一下!
Electric wrench is a power supply or battery powered wrench, which is a tool for tightening high-strength bolts, mainly divided into impact electric wrench, electric torque wrench, electric angle wrench, electric angle wrench. What are the differences between the five kinds of electric spanners? Wan Xiaobian today to introduce you!
電動扳手幾種類型的區(qū)別如下：
The differences of several types of electric wrench 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(zhǔn)螺栓扳動電源開關(guān)就行。
1. Impact electric wrench: it is mainly used to initially tighten the bolt. Its operation is simple, that is, to align the bolt and pull the power switch.
2.電動扭剪扳手：主要是終緊扭剪型高強螺栓的，它的使用就是對準(zhǔn)螺栓扳動電源開關(guān)，直到把扭剪型高強螺栓的梅花頭打斷為止。
2. Electric twist shear wrench: it is mainly used to tighten the twist shear high-strength bolt. Its use is to align the bolt and pull the power switch until the quincunx end of the twist shear high-strength 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(diào)節(jié)扭矩，再緊固螺栓。
3. Electric constant torque wrench: it can be used for both initial tightening and final tightening. Its use is to adjust the torque first and then tighten the bolts.
4.電動轉(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 degree of rotation 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 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.
古人云欲善其事必先利其器，市場上電動扳手的多種多樣，選擇一款稱心的電動扳手很重要，好的電動扳手都是有標(biāo)準(zhǔn)和檢驗程序的。
The ancients said that if you want to do a good job, you must first sharpen the tools. There are many brands of electric spanners in the market. It is very important to choose a satisfactory electric spanner. Good electric spanners have standards and inspection procedures.
