Referring to fig. 8, in the embodiment of the present invention, a first limiting rib 702 is disposed on a side surface of the first swing link 7, and the first limiting rib 702 abuts against the first spring shaft 701, so that the first swing link 7 is stable without an external force; the third swing link 9 is provided with a third limiting rib 903, and the third limiting rib 903 abuts against the first spring shaft 701, so that the third swing link 9 keeps the locking tooth 902 separated from the dewatering shaft tooth 242-1 under the condition of no external force.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
