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.

電動扭剪扳手的應用：扭剪型高強螺栓的初緊可使用沖擊電動扳手或定扭矩扳手,而終緊需要使用扭剪扳手，所以扭剪扳手是專門終緊扭剪型高強螺栓的。

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.

電動扭剪扳手的工作原理：電動扭剪扭扳手配有內外兩個套管，外套筒扭螺母，對螺栓施加扭矩，內套筒方向扭梅花頭，兩個扭矩大小相等，方向相反，尾部梅花頭擰掉，然后抽出扳手扣動扳機將梅花頭彈出，即結束工作。

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.

電動扭剪扳手相對來說操作方便，降低工人的勞動強度，提高了工作效率，現(xiàn)在市場上電動扳手廠家眾多，選擇一家好的電動扳手廠家十分重要。

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.
