The electric wrench is a wrench powered by a power supply or a battery, is a tool for screwing a high-strength bolt, and is also called a high-strength bolt gun. Mainly comprises an impact wrench, a torsional shear wrench, a fixed torque wrench, a corner wrench and an angular wrench. The electric wrench is mainly applied to the steel structure installation industry, and is specially used for installing steel structure high-strength bolts, and the high-strength bolts are used for being connected with steel structure contacts and are usually generated in a bolt group mode. The high-strength bolt is generally fastened firstly and then finally, and each step needs strict torque requirements. The initial tightening and the final tightening of the large-hexagon high-strength bolt must use a fixed torque wrench, so various electric wrenches are required for various tightening needs. The electric twist shear wrench is a necessary tool for the twisting operation of the twist shear quincuncial head bolt, helps people to assemble and disassemble the bolt and the nut, and can accurately control the twisting torque. The torque is fixed by the bolt, when the wrench reaches a certain torque, the quincunx head part of the bolt can be cut off, and the torque precision and the axial tension are ensured by the V-shaped notch of the fixed torque of the bolt. The assembly and disassembly torque is large, and the assembly and disassembly torque is safer and more reliable than that of manual assembly and disassembly torque. Convenient, beautiful, practical and convenient to carry on the vehicle. The method is widely applied to construction operation of facilities such as steel structure bridges, plants, power generation equipment and the like.
