[0013] By adopting the above technical solution, the first quick-release connector and the second quick-release connector enable quick disassembly, replacement and maintenance in case of damage.

[0014] Preferably, the motor cover has multiple heat dissipation holes.

[0015] By adopting the above technical solution and setting heat dissipation holes, heat dissipation can be assisted.

[0016] Preferably, one end of the mounting plate is provided with a mounting hole and a wire threading hole.

[0021] 1. In this application, an external rotor motor is used in conjunction with other components. The external rotor motor is installed inside the mounting housing via a motor fixing plate and connected to its internal components for use.

This provides protection for the external rotor motor and facilitates subsequent disassembly and assembly. Furthermore, the rivet gun in this application is driven by an external rotor motor, eliminating the need for other components. This further reduces the number of components used, thereby lowering maintenance costs and improving ease of maintenance.

[0022] 2. This application utilizes heat dissipation holes and other features, and through the turntable and fan blades set in the mounting plate, it can be connected and used with an external power motor to blow air to dissipate heat from the external rotor motor. Furthermore, by using it in conjunction with the heat dissipation holes, it facilitates the flow of gas for heat exchange, thus achieving the effect of cooling and heat dissipation.
