Specifically, as shown in fig. 4, the sliding rail 2 is disposed between two adjacent dust-proof strips 40, and since the dust-proof strips 40 can be elastically deformed under the condition of being pressed, the dust-proof strips 40 are elastically deformed in the contact area with the sliding rail 2, thereby preventing the dust-proof strips 40 from blocking the movement of the sliding rail 2, and ensuring that the sliding rail 2 can move along the length direction of the fixed rail 1. It can be understood that, under the condition that the dustproof strip 40 is not extruded by the sliding rail 2, two adjacent dustproof strips 40 can cover the avoiding opening 11, under the condition that the dustproof strip 40 is extruded by the sliding rail 2, the dustproof strip 40 is elastically deformed, so that the dustproof strip 40 is attached to the surface of the sliding rail 2, the sliding rail 2 is prevented from being blocked by the dustproof strip 40, and the sliding rail 2 is ensured to move along the fixed rail 1.
