When the motor 4 needs to be clamped, the adjusting screw 3 is rotated to move upward, the upper end of the adjusting screw 3 is in contact with the round shaft 2, and an upward thrust is applied to the round shaft 2 to push the round shaft 2 to move upward. The upward movement of the shaft 2 drives the special-shaped top block 12 to deform slightly and move upward. After the curved surface 121 of the special-shaped top block moves upward, it is in close contact with the outer wall of the motor 4, thereby clamping the motor 4; when the motor 4 needs to be loosened, Rotate the adjusting screw 3 in the opposite direction to move it downward, release the thrust applied to the round shaft 2, the round shaft 2 moves downward, and the special-shaped top block 12 and the curved surface 121 also move downward, thereby loosening the clamping of the motor 4 .
