冲击必威西汉姆联官网g1线路主要是初紧螺栓的，它的使用很简单，就是对准螺栓扳动电源开关就行。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。

The impact electric wrench is mainly used to tighten the bolt initially. Its use is very simple, that is, to align the bolt and pull the power switch. The electric wrench is mainly used to tighten the high-strength bolt. Its use is to align the bolt and pull the power switch until the quincunx head of the 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。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。电动角向扳手是一种专门紧固钢架夹角部位螺栓的必威西汉姆联官网g1线路，它的使用和电动扭剪扳手原理一样。

The electric constant torque wrench can be used for both initial tightening and final tightening. Its use is to adjust the torque first and then tighten the bolts. Electric angle wrench is also a kind of fixed torque wrench. Its use is to adjust the degree of rotation first, and then tighten the bolt. The electric angle wrench is a kind of electric wrench which is 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.
