[0019] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific connecting rod 202 described in the above embodiments. For example, the connecting rod 202 should be made of an integrated material, and the hinges at both ends should be further hardened and reinforced. The purpose of this arrangement is to prevent it from breaking during the pulling of the horizontal plate 201.

[0020] Specifically, a main shaft 204 is fixedly connected to the axis center of the other side of the eccentric wheel 203 , and the main shaft 204 is rotatably connected to the housing 101 .

[0021] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific main shaft 204 described in the above embodiments. For example, a bearing is provided at the connection between the main shaft 204 and the housing 101.

For example, the screw rod 302 can be replaced by a reciprocating screw rod. The purpose of this arrangement is that when the slide cylinder 304 threadedly connected thereto moves to one end, the screw rod 302 can be controlled to continue to rotate in the same direction, thereby quickly changing the movement direction of the slide cylinder 304.

[0030] Specifically, the slide cylinder 304 is fixedly connected with a slide plate 305 , and one end of the screw rod 302 is fixedly connected with a rotating wheel 303 .
