During the rotation of the Shanghai Pa bracket, it can be pressed on the sealing ring to change the sealing pattern, so that the sealing ring sinks a distance. The sealing ring is provided with a first deformation groove and a second deformation groove, which can facilitate the Shanghai Pa bracket to compress the sealing ring to deform and also facilitate recovery.

[0115] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
