The movable part 43 is sleeved on the lower sleeve and includes a movable sleeve 431, a positioning ball 432, a lifting spring 433 and a limiting ring 434. Two limiting rings 434 are provided. The two limiting rings 434 are arranged on the lower sleeve up and down. A limiting convex ring 435 with a trapezoidal cross-section is arranged on the inner side of the movable sleeve 431. The lifting spring 433 is arranged between the lower sleeve and the movable sleeve 431, and one end of the lifting spring 433 is in contact with one of the limiting rings 434, and the other end of the lifting spring 433 is in contact with the limiting convex ring 435. The positioning ball 432 is arranged between the lower sleeve and the movable sleeve 431, and the positioning ball 432 is arranged between the other limiting ring 434 and the lifting spring 433. The positioning ball 432 is arranged opposite to the positioning through hole 421; an operating ring 436 is arranged on the outer side of the movable sleeve 431.

[0035] During installation, the operating ring 436 is pressed by hand to make the movable sleeve 431 move downward, and the lifting spring 433 is compressed, so that the upper inner sleeve 412 in the upper connecting member 41 is inserted into the lower sleeve, and the limiting rod 422 is set in the limiting groove 414, so that the upper connecting member 41 does not rotate.
