[0050] The working principle of the present utility model is as follows: First, when the cabin needs to be spliced, the bottom plate 16 can be inserted into the two first I-shaped plates 2 first, then the panel 4 is inserted into the two second I-shaped plates 5, and then the back plate 14 is inserted into the other two second I-shaped plates 5. Next, the top plate 11 is inserted into the other two first I-shaped plates 2, so that the splicing of the cabin can be completed. After the splicing is completed, at this time, the locking grooves 901 on the bottom plate 16 and the top plate 11 will be aligned with the locking plates 902. Then, the staff rotates the rotating shaft 913 through the handwheel 910. The rotating shaft 913 drives the threaded rod 907 to rotate. The threaded rod 907 drives the movable seat 908 to move, and pushes the push plate 909 to rotate, and then drives the locking plate 902 to move, so that the locking plate 902 is inserted into the corresponding locking groove 901, thereby limiting and fixing the bottom plate 16 and the top plate 11, preventing the top plate 11 and the bottom plate 16 from moving randomly. At the same time, the locking bolt 911 is screwed into the threaded hole 912 to lock the handwheel 910 and the rotating shaft 913. The setting of the first gasket 3 and the second gasket 15 can improve the sealing performance of the spliced cabin;
