The connecting mechanism 2 is arranged at the upper center of the connecting plate 1, and is used for assembly and connection with a screw rod 16 to limit and shape multiple groups of mutually interlocking steel plates. The clamping mechanism 3 is arranged on the bottom wall of the connecting plate 1. The clamping mechanism 3 is arranged in a cross shape and is symmetrically distributed in pairs. A clamping groove 4 is formed between the two symmetrical clamping mechanisms 3, which contacts the steel plate to achieve limiting.

[0019] like Figure 4 and Figure 5 As shown, in order to realize the positioning of the buckled connection of the steel plate, the clamping mechanism 3 includes a limiting column 5, the upper end of the limiting column 5 is fixedly connected to the bottom wall of the connecting plate 1, the limiting columns 5 are symmetrically arranged in a cross shape, the bottom wall of the limiting column 5 is provided with a baffle 6, the outer wall of the limiting column 5 is provided with a rubber sleeve 7, the rubber sleeve 7 is arranged in an inverted frustum shape, the rubber sleeve 7 is located between the connecting plate 1 and the baffle 6, the limiting column 5 is used for supporting the rubber sleeve 7, the rubber sleeve 7 increases the friction with the side wall of the steel plate, improves the locking force of the limiting column 5, and is clamped in At the cross connection of the buckled steel plates, a rubber ring 8 is fixedly connected to the outer circumference of the upper end surface of the rubber sleeve 7, and a support spring 9 is wound around the upper part of the outer wall of the limit column 5. The support spring 9 is arranged at the upper end of the limit column 5 and is located in the rubber ring 8. The rubber sleeve 7 can slide up and down on the outside of the limit column 5. Under the support of the support spring 9, the rubber sleeve 7 is maintained at the lower part of the outer side of the limit column 5 and in contact with the baffle 6 to avoid misalignment of the rubber sleeve 7 when pressed. The rubber ring 8 is used to increase the supporting force of the support spring 9 and protect the outer side of the support spring 9 at the same time.

[0020] like Figure 2-5 As shown, in order to increase the connectivity of the device, facilitate the assembly of multiple devices, and realize the positioning of the grid-like steel plate connection after assembly, the connecting mechanism 2 includes a connecting ring 10, a rotating block 11 and a connecting block 12.
