The friction between the slider 6 and the slide rail 7 is reduced with the help of the roller 8 at the bottom end of the slider 6, so that the rotating rod 9 can control the movement of the sliding door 5. A rubber anti-collision strip 11 is installed at one end of the partition plate 4. When the sliding door 5 moves to the edge of the slide rail 7, the anti-collision strip 11 is used to reduce the impact force of the sliding door 5 to avoid collision and noise when the sliding door 5 moves.
