The two moving blocks 5 are fixedly connected to the opposite side of the two moving blocks 5 with a locking piece 6. The steel truss 9 is locked by the locking piece 6. The locking plate 2 is fixedly connected on both sides. Disassembly block 8, a steel truss 9 is provided on the top of the locking plate 2, and the bottom of the bottom template 1 is penetrated and provided with evenly distributed screws 11, the screws 11 are threadedly connected to the disassembly block 8, and the bottom template 1 is connected to the disassembly block 8 by the screws 11. A first slot 12 is provided at the front and rear ends of the right side of the bottom template 1, and a rotating shaft 16 is fixedly connected in the first slot 12. The rotating shaft 16 is rotatably connected to the outside of the connecting plate 17, and the connecting plate 17 is conveniently rotated by the rotating shaft 16. A limiting through hole 18 is penetrated and provided in the connecting plate 17. The limiting through hole 18 is the same shape as the limiting knob 15, and a limiting component is provided at the front and rear ends of the left side of the bottom template 1.

The limiting assembly can conveniently limit and fix the connecting plate 17, so that multiple groups of bottom templates 1 can be spliced or disassembled as needed.

[0033] Reference Figure 1 、 Figure 2 and Figure 3 The movable block 5 is arranged in the installation groove 3, and the outside of the movable block 5 is slidably connected to the inner wall of the installation groove 3. The movable block 5 can be limited by the installation groove 3. The left end of the two-way threaded rod 4 is fixedly connected with a knob 7.
