[0025] In the embodiment, the slider body 2 is symmetrically provided with a receiving groove 211 capable of accommodating the movable plate 212, and the receiving groove 211 is slidably connected with a sliding plate 215 movable towards the slider body 2 on both sides. The sliding plate 215 is connected with a rotating shaft 214 penetrating the movable plate 212 between the two sliding plates 215. By adjusting the position of the sliding plate 215, the position of the movable plate 212 can be changed, thereby realizing fine adjustment of the cooperation between the ball group 213 and the guide rail body 1. The movable plate 212 is rotatably connected with the rotating shaft 214. When the ball on one of the ball groups 213 of the movable plate 212 contacts the guide rail body 1, the movable plate 212 will tilt, causing the ball on the other ball group 213 to move towards the guide rail body 1. This makes the balls in the ball group 213 more easily adhere to the guide rail body 1, further enhancing the stability of movement.
[0026] In the embodiment, the slider body 2 includes a pair of side rails 21. The top of the two side rails 21 is connected with a top plate 22.
