[0002] An electric wrench refers to an electric tool for tightening and loosening bolts and nuts, and is a tool for tightening high-strength bolts. It is widely used in industries such as automobiles, electric motors and electrical appliances, power machinery, valves, water pumps, and textile machinery. It is used for the initial tightening, final tightening of large hexagon head high-strength bolts in the construction of steel structure bridges, factory buildings, chemical industries, and power generation equipment installations, and the initial tightening of torsion shear type high-strength bolts, as well as occasions where strict requirements are imposed on the torque or axial force of bolt fasteners.

[0003] When an electric wrench tightens and loosens bolts and nuts, there is no device for positioning and clamping the bolts and nuts, resulting in the looseness of the bolts and nuts during tightening and loosening, and thus falling off. At this time, the operator needs to work on them again, which is very time-consuming and laborious, and reduces the working efficiency of the electric wrench. Content of the Utility Model
