Referring to fig. 8, in the embodiment of the present invention, a first limit rib 702 is disposed on a side surface of the first swing link 7, and the first limit rib 702 abuts against the first spring shaft 701, so that the first swing link 7 is kept stable under the condition of not receiving an external force; the third swing rod 9 is provided with a third limit rib 903, and the third limit rib 903 is abutted against the first spring shaft 701, so that the third swing rod 9 keeps the locking teeth 902 to be separated from the dewatering shaft teeth 242-1 under the condition of no external force.

The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
