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。

Impact electric wrench: mainly used for initial tightening of bolts, its operation is simple, just align the bolt and pull the power switch.

電動扭剪扳手：主要是終緊扭剪型高強(qiáng)螺栓的，它的使用就是對準(zhǔn)螺栓扳動電源開關(guān)，直到把扭剪型高強(qiáng)螺栓的梅花頭打斷為止。

Electric torsion shear wrench: mainly used for final tightening of torsion shear high-strength bolts. Its use is to align the bolt and pull the power switch until the plum blossom head of the torsion shear high-strength bolt is broken.

電動扳手百科知識：電動扳手使用準(zhǔn)則

Encyclopedia of Electric Wrenches: Guidelines for Using Electric Wrenches

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。

Electric fixed torque wrench: It can be used for both initial and final tightening. Its use is to first adjust the torque and then tighten the bolts.

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。

Electric angle wrench: It mainly belongs to a type of fixed torque wrench, and its use is to adjust the degree of rotation first, and then tighten the bolt.

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。

Electric angle wrench: It is a type of electric wrench specifically designed to tighten bolts at the angle of a steel frame, and its use is similar to the principle of an electric torsion wrench.

電動扳手的優(yōu)勢

The advantages of electric wrenches

精準(zhǔn)性高

High precision

工業(yè)電動扳手扭矩的調(diào)節(jié)是比較精準(zhǔn)的，這樣在進(jìn)行實(shí)際操作的時(shí)候能夠準(zhǔn)確地?cái)Q緊扭矩，提高操作的效率。而質(zhì)量比較差的電動扳手在操作的時(shí)候會出現(xiàn)距離上面的誤差，影響正常使用。

The torque adjustment of industrial electric wrenches is relatively precise, so that the torque can be accurately tightened during actual operation, improving operational efficiency. However, electric wrenches with poor quality may experience distance errors during operation, which affects normal use.

使用壽命長

Long service life

電動扳手使用的壽命都比較長，功率也比較大，而且整體來說是比較省電的，早操作的時(shí)候也不會發(fā)出很大的噪聲，因?yàn)樵诓僮鞯臅r(shí)候難免會有發(fā)生撞擊的情況，而好的電動扳手外部的材料比較堅(jiān)固，所以比較耐撞擊。

Electric wrenches have a relatively long lifespan, high power, and are generally more energy-efficient. They do not emit significant noise when operated early, as there may be collisions during operation. Good electric wrenches have sturdy external materials, making them more resistant to impacts.
