[0029] Two horizontal beams 4 are distributed up and down, and slide grooves 5 are provided on both sides of the horizontal beam 4. Both sides of the bottom of the horizontal beam 4 are provided with horizontal grooves 6 connected with the slide grooves 5. The inner side of the slide groove 5 is slidably connected with an extension beam 7. The surfaces of the horizontal beam 4 and the extension beam 7 are evenly spaced with mounting grooves 8. One end of the extension beam 7 is fixedly connected with an embedded block 10 slidably set in the embedded groove 3, and the embedded block 10 is a T-shaped block.

[0030] A vertical beam 9 is arranged between two upper and lower horizontal beams 4 and between two upper and lower symmetrically arranged extension beams 7, and both ends of the vertical beam 9 are arranged in two upper and lower corresponding mounting grooves 8. The vertical beam 9 includes a vertical rod 91, and a mounting hole 92 is opened at one end of the vertical rod 91. A compression spring 93 is fixedly connected to the inner side of the mounting hole 92, and an insertion head 94 is fixedly connected to one end of the compression spring 93. One end of the insertion head 94 and one end of the vertical rod 91 are both extended into the mounting groove 8. Short rods 95 are fixedly connected on both sides of the insertion head 94. Open grooves 96 communicating with the mounting holes 92 are opened on both sides of the vertical rod 91. The short rod 95 is penetrated and arranged in the open groove 96. When the short rod 95 is pulled, the short rod 95 can be slid in the open groove 96 manually or with a tool.
