Description

A rechargeable torque wrench

Technical Field

The utility model relates to the field of electric wrenches, in particular to a charging torque wrench.

Background Art

A rechargeable torque wrench, also called an electric torque wrench, is an electric tool for tightening and loosening bolts and nuts. It is a tool for tightening high-strength bolts. It is used for the initial tightening and final tightening of large hexagonal high-strength bolts installed in steel structure bridges, factory buildings, chemical industry, and power generation equipment, as well as the initial tightening of torsion shear type high-strength bolts, and in situations where there are strict requirements on the torque or axial force of bolt fasteners.

Common high-torque electric wrenches generally use a screw connection to assemble and fix the mounting base and the sleeve. However, this method of assembly through screws requires the user to tighten the screws on both sides of the mounting base in turn to complete the assembly between the two during use. The operation steps are cumbersome. When tightening or disassembling nuts of different sizes, it is not convenient to quickly install and remove the sleeve, which affects the user's normal work progress.
