[0002] When removing or tightening bolts in flammable or explosive environments in mines and other places, an explosion-proof electric wrench is required. The authorization document with application number CN118952097A discloses an explosion-proof electric wrench. The mining explosion-proof electric wrench is mainly composed of an electric motor, a planetary gear reducer, a power switch, a phase-changing switch, a ball screw groove impact mechanism, an explosion-proof plug, and a mining power cord. The motor is installed inside a housing with an explosion-proof and explosion-proof design. The principle of the explosion-proof electric wrench is that the motor drives the striking block to rotate, causing repeated collisions with the square shaft, thereby generating a strong impact force to tighten or remove bolts.

[0003] When using an explosion-proof electric wrench to remove a nut in a mine, the nut sleeve on the electric wrench is set on the outside of the nut. When the switch is turned on, the main shaft is driven to drive the nut sleeve to rotate to remove the nut. During the above operation, the nut and the nut sleeve cooperate, and the removed nut may remain inside the nut sleeve, and the nut cannot fall off smoothly. The explosion-proof electric wrench does not have a knocking design to knock the nut inside the nut sleeve to make it fall off, which is insufficient.

[0004] When removing a nut with an existing explosion-proof electric wrench, there is a problem that the explosion-proof electric wrench does not have a knocking design for knocking the nut sleeve to remove the nut. Therefore, the present application proposes a mining explosion-proof electric wrench. Utility Model Content
