By operating the button 302, the spring 303 generates pressure, so that the locking plate 304 descends and the clamping plate 307 clamps the main shaft body 8. When the locking plate 304 descends, it drives the lower pressure plate 306 and the clamping plate 307 to press down. After the clamping plate 307 and its main shaft body 8 are fitted with each other, the locking plate 304 is rotated by rotating the button 302 to rotate the locking plate 304 to the inside of the groove 305 for effective limiting, which can effectively fix the main shaft body 8 so that it will not loosen or deviate when the motor is running.

[0036] Working principle: By operating the button 302, the spring 303 generates pressure, so that the locking plate 304 descends and the clamping plate 307 clamps the main shaft body 8. When the locking plate 304 descends, it drives the lower pressure plate 306 and the clamping plate 307 to press down. After the clamping plate 307 and its main shaft body 8 are fitted with each other, the locking plate 304 is rotated to the inside of the groove 305 by rotating the button 302 for effective limiting. The main shaft body 8 can be effectively fixed so that it will not loosen or deviate when the motor is running. The support of the bearing 502 and the fixation of the positioning plate 501 ensure that the main shaft body 8 maintains an accurate position and stability during rotation. The bearing 502 provides support for the main shaft body 8 , reducing the friction during rotation. At the same time, the annular arrangement design of the positioning plate 501 helps to maintain the horizontal position of the main shaft body 8, effectively preventing it from offsetting or shaking. When the equipment is operating, the hot air is discharged through the exhaust port 401, and the adsorption cotton 402 absorbs the heat therein and helps dissipate the heat. The placement groove 403 and the fan blade 404 contribute to air flow and heat dissipation. The rotation heat of the fan blade 404 is finally discharged to the exhaust port 401 through the air outlet slot 405. After the hot air is discharged to the exhaust port 401, it is effectively discharged from the equipment through the exhaust port 401 to maintain the normal operating temperature of the motor body 1. Through a good heat dissipation design, the damage to the motor body 1 caused by overheating can be effectively avoided, ensuring the continuous and stable operation of the equipment.
