The slider slides with the guide rail through the balls, and the outer wall of the slider is provided with a mounting groove corresponding to the balls. The mounting groove is provided with an exploration hole near one end of the slide groove, and the balls are removably installed in the mounting groove, and one end of the balls extends out of the exploration hole.
