One side of the first clamping part 3 is connected with an output shaft of the motor 1 and can rotate along with the output end of the motor 1. One end of the connecting rod 5 is fixedly connected with the first clamping part 3, and the other end of the connecting rod 5 is elastically connected with the second clamping part 4 through an elastic connecting piece 6. Specifically, the second clamping part 4 is provided with a second through hole, and the connecting rod 5 penetrates through the second through hole to be installed in a matching way. The connecting rod 5 is provided with spacing boss 501 in the one end that is located second clamping part 4 below, and the one end butt of elastic connection spare 6 is on spacing boss 501, and the other end butt of elastic connection spare 6 compresses tightly second clamping part 4 and first clamping part 3 through elastic connection spare 6 upwards extrusion in the below of second clamping part 4.

The cylinder 2 is fixedly connected with the motor 1 body through a bracket and is used for pushing the second clamping part 4 to be separated from the first clamping part 3. Specifically, the cylinder 2 is connected with the main body of the motor 1 through an L-shaped sheet metal part bracket, and the cylinder 2 is arranged above the first clamping part 3. The actuating end of the cylinder 2 is facing the first through hole, and can pass through the first through hole to push the second clamping part 4. Because the cylinder 2 is fixedly connected with the motor 1 body, the cylinder 2 cannot rotate along with the rotation of the motor 1, and only when the first clamping part 3 and the second clamping part 4 rotate to specific positions, the actuating end of the cylinder 2 can be aligned with the first through hole, and at the moment, the actuating end of the cylinder 2 can extend, so that motion interference does not exist.
