1.沖擊電動(dòng)扳手：主要是初緊螺栓的，它的操作簡單，就是對(duì)準(zhǔn)螺栓扳動(dòng)電源開關(guān)就行。
1. Impact electric wrench: mainly used for initial tightening of bolts, its operation is simple, which is to 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強(qiáng)螺栓的，它的使用就是對(duì)準(zhǔn)螺栓扳動(dòng)電源開關(guān)，直到把扭剪型高強(qiáng)螺栓的梅花頭打斷為止。
2. Electric shear wrench: mainly used for final tightening of shear type high-strength bolts. Its use is to align the bolt and pull the power switch until the plum blossom head of the shear type high-strength 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 fixed torque wrench: It can be used for both initial and final tightening. Its use involves adjusting the torque first and then tightening 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 type of fixed torque wrench, which is used 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 a type of electric wrench specifically used to tighten bolts at the angle of the steel frame, and its use is the same as that of an electric torsion wrench.
