[0002] Motor is the core power source of equipment, and the replacement of motor is an important task in equipment maintenance. On the one hand, the aging of motor may have safety hazards, such as overheating and electric leakage. On the other hand, the failure of motor may also cause damage to other components of the equipment. Therefore, timely replacement of damaged or aged motor can significantly prolong the overall life of the equipment, improve the safety of equipment operation, and avoid unnecessary losses caused by equipment downtime due to motor failure.

[0003] However, if the motor is exposed to a humid or corrosive environment for a long time, it may be difficult to dismount due to severe corrosion or rust. Moreover, if the space where the motor is located is narrow, the use of traditional dismounting tools may increase the difficulty of dismounting. Furthermore, the shaft coupling on the motor is also a dismounting challenge. Since the shaft coupling and the shaft are usually fitted with an interference fit, heating or pressurization is required during installation. Therefore, it is often difficult to separate them during dismounting. In addition, after long-term operation, burrs may be generated on the inner hole of the shaft coupling and the surface of the shaft due to wear, or the shaft coupling may be stuck due to deformation, hindering the dismounting of the shaft coupling. Therefore, traditional motor replacement often requires a large amount of manpower and resources, and is inefficient, taking a long time to replace. SUMMARY
