The side wall of the sliding block 21 is provided with an inclined groove 23, and one end of the sliding shaft 25 away from the sliding frame 24 is attached to the inner wall of the inclined groove 23. When the sliding shaft 25 is attached to the inner wall of the inclined groove 23 and moves, it will push the sliding block 21, so that the sliding block 21 slides on the inner wall of the motor body 1. The outer wall of the motor body 1 is slidingly connected with the sliding frame 24, and the sliding frame 24 is a hollow "mouth" structure. The inner wall of the sliding frame 24 is fixedly installed with the sliding shaft 25, and the outer wall of the sliding shaft 25 is attached to the inner wall of the through groove 4. The sliding frame 24 slides on the outer wall of the motor body 1, and the sliding shaft 25 attached to the inner wall of the through groove 4 moves synchronously. The through hole 22 is internally provided with a bolt 26 for mounting the motor body 1.
