The electric shear wrench is a tool for final tightening of high-strength bolts of the shear type. There are generally electric shear wrenches and manual shear wrenches, among which the electric shear wrench is relatively common. At present, the shear type bolts are widely used in the construction steel structure installation industry, and a small part of them are also used for automobile assembly. Now let's introduce the working principle of the electric shear wrench specifically by Shandong Hampu Machinery Industry Co., Ltd.

电动扭剪扳手的应用：扭剪型高强螺栓的初紧可使用冲击电动扳手或定扭矩扳手,而终紧需要使用扭剪扳手，所以扭剪扳手是专门终紧扭剪型高强螺栓的。

Application of electric shear wrench: impact electric wrench or constant torque wrench can be used for initial tightening of shear type high-strength bolts, while the final tightening requires the use of a shear wrench, so the shear wrench is specially used for final tightening of shear type high-strength bolts.

电动扭剪扳手的工作原理：电动扭剪扭扳手配有内外两个套管，外套筒扭螺母，对螺栓施加扭矩，内套筒方向扭梅花头，两个扭矩大小相等，方向相反，尾部梅花头拧掉，然后抽出扳手扣动扳机将梅花头弹出，即结束工作。

Working principle of electric torque shear wrench: the electric torque shear wrench is equipped with two sleeves inside and outside. The outer sleeve twists the nut to apply torque to the bolt. The inner sleeve twists the box head. The two torques are equal in size and opposite in direction until the box head at the end is unscrewed. Then pull out the wrench and pull the trigger to eject the box head, which ends the work.

电动扭剪扳手相对来说操作方便，降低工人的劳动强度，提高了工作效率，现在市场上电动扳手厂家众多，选择一家好的电动扳手厂家十分重要。

The electric wrench is relatively easy to operate, which reduces the labor intensity of workers and improves the work efficiency. Now there are many manufacturers of electric wrench in the market, so it is important to choose a good manufacturer of electric wrench.
