[0027] A connecting hole 123 is provided at the geometric center of the socket 12, and a limiting groove 122 is provided at the bottom of the socket 12. The connecting hole 123 is smaller than the limiting groove 122. The shape and size of the connecting hole 123 are the same as the inner diameter of the fixing seat 11, and the shape and size of the limiting groove 122 are the same as the outer diameter of the fixing seat 11. A sealing gasket 121 is provided on the surrounding side of the limiting groove 122.
