[0015] The beneficial effects of the utility model are as follows:

[0016] 1. The outer rail and the retainer are connected through the synchronous part, the elastic claw of the synchronous part is clamped in the retainer, thereby further associating the outer rail and the retainer, ensuring synchronous movement of the two, and avoiding easy disengagement of the outer rail and the retainer in the process of use.

[0017] 2. The elastic claw wall three and the side wall one are attached, and the elastic claw side wall four and the side wall two are abutted, thereby restraining the elastic claw from the inside and outside, further increasing the contact area of the two, and improving the stability of clamping.
