[0002] After the server cabinet is assembled, it is necessary to put the pull-out shelves in the stacked intervals. The existing pull-out shelves are all equipped with a whole slide rail on the outside of the side frame. In actual use, the rear end of the slide rail needs to be convex according to the depth of the rear end of the cabinet. The existing pull-out shelf structure needs to assemble slide rails of different lengths according to the convex depth, resulting in the need to configure different slide rail structures, which makes the adaptability and versatility of the slide rail relatively poor; and the pull-out handles of the existing pull-out shelf are directly connected to the front end plate of the pull-out shelf by bolts through the screw holes embedded in the inner end of the bent pipe. During the actual pulling and pulling operation, the bolts are prone to loosening, which makes the handles easy to loosen and need to be tightened frequently, which is not conducive to the stable and reliable use of the entire pull-out shelf. For this reason, it is urgently needed to develop a pull-out shelf with good slide rail versatility and suitable for stable and reliable pulling and pulling. Summary of the Invention
