After the cutting is completed, the motor 6 is started, and the transmission rod 7 is driven to rotate under the movement of the motor 6. Then, the connecting rod 18 is driven to move under the rotation of the transmission rod 7, so that the top of the connecting rod 18 drives the connecting rod 2 9 to move, and then the other end of the connecting rod 2 9 drives the connecting rod 10 to move, and then the movement of the connecting rod 10 drives the pushing block 11 to clean the debris.
