[0033] And a transmission assembly located between the two groups of connecting boxes 1, the transmission assembly includes a connecting assembly, a transmission shaft 4 and a connecting ring 11, the connecting assembly is used for the connection between the two groups of connecting boxes 1, the transmission shaft 4 is rotatably installed in the connecting box 1, and two groups of transmission shafts 4 are provided, the ends of the transmission shafts 4 are fixedly installed with mounting blocks 8, the mounting blocks 8 are fixedly installed with semicircular plates 9, and semicircular parts are slidably installed in the semicircular plates 9, and the connecting ring 11 is used for the rotational connection between the two groups of semicircular parts.

[0034] The present invention also has advantages that: first, it is convenient to realize the connection between the building block 20 and the connecting box 1, and second, it is convenient to realize the connection between the building block 20 and the connecting box 1 by the matching setting of the connecting column 22 and the plug hole 3. At the same time, the locking assembly can be used to further fix the connecting column 22, thereby improving the stability of the connection between the connecting box 1 and the building block 20. The connecting assembly can realize the rotation connection between the two groups of connecting boxes 1. The matching setting between the semicircular part and the connecting ring 11 can realize the connection between the two groups of semicircular plates 9, and the matching setting between the two groups of transmission shafts 4 can be realized by matching the mounting block 8, so as to realize the linkage between the two groups of transmission shafts 4 and realize power transmission at any angle. Compared with the prior art, the present invention avoids the problem that most of the existing connection structures are simple in structure, only use plastic shafts for power transmission, cannot realize power transmission at different angles, and have certain limitations through the matching setting of the connecting box 1, the locking assembly and the transmission assembly.

[0035] In one embodiment of the present invention, please refer to Figures 1-6, the connecting assembly includes a support plate 5, a support frame 6 and a connecting shaft 7, the support plate 5 is fixedly installed on each of the two sets of connection boxes 1, and the two sets of support plates 5 are provided with grooves, the connecting shaft 7 is used for the rotation connection between the two sets of support plates 5, and the support frame 6 is fixedly installed on the support plate 5;
