Preferably, a second-stage ball frame is arranged between the outer walls of the two sides of the middle rail and the inner walls of the two sides of the outer rail, and the second-stage ball frame is in rolling contact with the middle rail and the outer rail simultaneously. The sliding connection between the outer rail and the middle rail can be realized by utilizing the two-stage ball frame, and the friction resistance between the outer rail and the middle rail is reduced.

Preferably, the end part of the outer rail is provided with a limit baffle, and simultaneously the middle rail is provided with an anti-collision block at the same side of the limit baffle. Utilize limit baffle can prevent well rail and follow the tip of outer rail and deviate from, the anticollision piece can cushion the well rail when shrink between the striking between rail tip and the outer rail, and the anticollision piece also plays spacing and crashproof effect to the inner rail simultaneously, prevents that the inner rail from deviating from and buffering the striking between inner rail and the well rail from the middle rail tip.
