[0021] A clutch rod 5 is rotatably connected to the middle position of the support rod 4, a protective cover 2 is fixedly provided on the top of the support rod 4 of the working box 1, a make way groove 22 is opened on the protective cover 2 at the position of the clutch rod 5, a release fork 6 is fixedly provided on the bottom of the clutch rod 5, a conical disk 9 is fixedly provided on one end of the extension shaft 7 close to the driven cylinder 3, and an anti-mistouch component is provided along the vertical direction of the clutch rod 5 to prevent accidental movement of the clutch rod 5.

[0022] A conical cavity 31 is provided on one side of the driven cylinder 3 near the conical disk 9, and the inner wall of the conical cavity 31 and the outer wall of the conical disk 9 are both set to be frosted surfaces. A driving ring 8 is fixedly provided on the extension shaft 7 below the release fork 6, and the release fork 6 extends into the ring groove of the driving ring 8. The anti-mistaken touch component includes a mounting block 13, a guide column 12, a safety block 10, and a safety rod 15. A release groove 14 is provided on the side of the safety rod 15, and the safety block 10 is movably inserted into the release groove 14. The top surface of the safety block 10 and the top of the release groove 14 are both set to be inclined surfaces.

[0023] A guide column 12 is fixedly provided on the side of the safety block 10 away from the safety rod 15. The guide column 12 is movably inserted into the side of the mounting block 13. The bottom of the mounting block 13 is fixedly connected to the top of the clutch rod 5. The side of the mounting block 13 is fixedly connected to one end of the connecting spring 11, and the other end of the connecting spring 11 is fixedly connected to the side of the safety block 10.
