The limiting member 122 is fixedly connected to the outer side of the intermediate member 101 and is located on the side of the installation groove 116. The pushing member 121 is movably installed inside the limiting member 122. Moving the pushing member 121 in the direction of the first rotating member 118 causes the pushing member 121 to slide in the limiting member 122 and push the second rotating member 120 to move upward. The second rotating member 120 is rotatably connected to the first rotating member 118, so that the first rotating member 118 and the second rotating member 120 are convenient for forming a V-shaped structure to block the movement of the steel balls 107 above and below the storage hole 109.

[0025] It should be noted that the present utility model is a steel ball stable slide rail. The locking bolt 105 sequentially passes through the third connecting member 104, the second connecting member 103 and the first connecting member 102 and is fixedly connected to the screw hole of the intermediate member 101. By turning the locking bolt 105 with an external screwdriver, the first connecting member 102, the second connecting member 103 and the third connecting member 104 are convenient to disassemble. The upper end and the lower end of the intercepting rod 106 are fixedly connected in the connecting groove 113 of the second connecting member 103 and are connected by clamping. The intercepting rod 106 is removed from the connecting groove 113, so that the intercepting rod 106 is convenient to disassemble, and the components of the slide rail 1 are convenient to assemble and disassemble, which is convenient for maintenance and replacement. The steel ball 107 is movably installed in the movable groove 108. The intercepting rod 106 is located in the limiting groove 4. The two sides of the steel ball 107 are in contact with and slide on the inner walls of the two sides of the sliding groove 3, so that the slider 2 is slidably connected in the slide rail 1. The intercepting rod 106 is located on the side of the steel ball 107, so that the steel ball 107 is not easy to fall off, and the use stability is higher. The steel ball 107 can enter the receiving hole 109 through the first guiding groove 110 and the second guiding groove 111, so that the steel ball 107 flows between the receiving hole 109 and the movable groove 108. Some spare steel balls 107 can be arranged in the receiving hole 109. When the steel ball 107 in the movable groove 108 is damaged, by pushing the intercepting rod 106 sideways, the broken steel ball 107 is convenient to remove, or the broken steel ball 107 can be rotated into the receiving hole 109, and then the pushing member 121 is pushed towards the position of the first rotating member 118, so that the second rotating member 120 is convenient to move upward. The second rotating member 120 is rotatably connected to the first rotating member 118, so that the first rotating member 118 rotates upward synchronously, thus forming a V-shaped structure. Above and below the receiving hole 109, the broken steel ball 107 is restricted in the receiving hole 109 by the V-shaped first rotating member 118 and the second rotating member 120. Or when the steel ball 107 in the movable groove 108 is broken and falls off, the pushing member 121 in the installation groove 116 is pulled backward, so that the first rotating member 118 and the second rotating member 120 are kept in a straight line and do not block the rolling of the steel ball 107, so that the steel ball 107 in the receiving hole 109 is moved into the movable groove 108 to replace and supplement the broken and fallen steel balls 107.
