冲击电动扳手：主要是初紧螺栓的，它的操作简单，就是对准螺栓扳动电源开关就行。

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

电动扭剪扳手：主要是终紧扭剪型高强螺栓的，它的使用就是对准螺栓扳动电源开关，直到把扭剪型高强螺栓的梅花头打断为止。

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.

电动定扭矩扳手：既可初紧又可终紧，它的使用是先调节扭矩，再紧固螺栓。

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.

电动转角扳手：主要也属于定扭矩扳手的一种，它的使用是先调节旋转度数，再紧固螺栓。

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.

电动角向扳手：是一种专门紧固钢架夹角部位螺栓的电动扳手，它的使用和电动扭剪扳手原理一样。

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.

电动扳手的优势

The advantages of electric wrenches

精准性高

High precision

工业电动扳手扭矩的调节是比较精准的，这样在进行实际操作的时候能够准确地拧紧扭矩，提高操作的效率。而质量比较差的电动扳手在操作的时候会出现距离上面的误差，影响正常使用。

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.

使用寿命长

Long service life

电动扳手使用的寿命都比较长，功率也比较大，而且整体来说是比较省电的，早操作的时候也不会发出很大的噪声，因为在操作的时候难免会有发生撞击的情况，而好的电动扳手外部的材料比较坚固，所以比较耐撞击。

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.
