[0021] See also Figure 1 to Figure 5In an embodiment of the utility model, a ball guide rail slider assembly includes a guide rail 1, and ball grooves 2 are opened on the top and sides of the two corners of the top of the guide rail 1. The outer wall of the guide rail 1 is slidably connected with a slider 3, and the slider 3 is slidably connected to the guide rail 1 through the ball assembly and the ball groove 2; the ball assembly is slidably connected inside the slider 3, and the outside of the slider 3 is connected to an adjustment assembly connected to the ball assembly, and the adjustment assembly is used to adjust the clamping force between the ball assembly and the ball groove 2; the adjustment assembly is threadedly connected to the guide rail 1, and the adjustment assembly is rotatably connected to the ball assembly.

[0022] In this embodiment: when the slider 3 moves along the surface of the guide rail 1, the slider 3 with the ball assembly and the ball groove 2 slide against each other, and the ball assembly and the ball groove 2 can effectively reduce the friction generated by the slider 3 during the movement. When the slider 3 and the guide rail 1 are installed, the pressure between the ball assembly and the ball groove 2 can be adjusted by rotating the adjustment component to achieve a sliding process that is neither loose nor too tight, thereby improving the adaptability between the guide rail 1 and the slider 3.
