In this technical solution, the spatial positions of the first limit protrusion and the second limit protrusion are respectively on the movement trajectory of the limit block. When the limit block enters the limit space, the first limit protrusion and the second limit protrusion The limit protrusion can limit the limit block to rotate in two directions, clockwise and counterclockwise, so as to limit the rotation of the motor rotating part relative to the fixed part. The specific locking process is as follows: at the initial moment, the limit block is located outside the limit space, the rotating part drives the limit block to rotate under the action of external force, squeezes the second limit protrusion on the shrapnel, and the second limit protrusion occurs Elastic deformation, the limit block rotates to the limit space, the external force acting on the second limit protrusion disappears, the second limit protrusion returns to its original shape, and the limit block is always located in the limit space without the action of external force.
