The sliding setting of the lifting rod can lift the cover plate to further expand the space of the cabin. The rotating setting of the lifting rod can make the lifting rod extend out of the long board or short board and abut against the cabin body to support the long board or short board by rotating the lifting rod when the long board or short board is used as a canopy; 5. Due to the detachable setting of the expansion cabin, the cabin body needs to have its own top plate to ensure that the cabin body can become a sealed cabin alone after the expansion cabin is removed. However, the existence of the top plate will affect the expansion of the cabin when it is expanded. By cooperating with the positioning block, the top plate is driven to rotate and connect the cabin body and the expansion cabin while the expansion cabin is sliding and expanding, reducing the impact of the cabin body setting the top plate on the expansion. At the same time, the top plate can also be used as a support for the cover plate to improve the structural strength of the expansion cabin. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the driving block 14 is separated from the top plate 104, and the top plate 104 is reset under the action of its own gravity. Due to the detachable setting of the expansion cabin 3, the cabin body 1 needs to have its own top plate 104 to ensure that the cabin body 1 can become a sealed square cabin alone after the expansion cabin 3 is dismantled. However, the existence of the top plate 104 will affect the expansion of the square cabin when the square cabin is expanded. Through the driving block 14 and the positioning block 13, the top plate 104 is driven to rotate to connect the cabin body 1 and the expansion cabin 3 while the expansion cabin 3 is sliding and expanding, reducing the influence of the cabin body 1 setting the top plate 104 on the expansion, and at the same time, the top plate 104 can also be used as a support for the covering plate 303 to improve the structural strength of the expansion cabin 3.

[0039] The implementation principle of the embodiment of the present application is as follows: when the cabin needs to be expanded, the expansion cabin 3 is driven to slide, and the positioning block 13 slides in the positioning groove 12. When the positioning block 13 slides to the top of the positioning groove 12, the positioning block 13 drives the driving block 14 to slide, and the driving block 14 abuts against the top plate 104 to rotate. The top plate 104 completes the expansion of the cabin space by rotating the connecting cabin body 1 and the expansion cabin 3; when the cabin needs to be expanded again, the lifting rod 8 is driven to slide, and the lifting rod 8 drives the covering plate 303 to slide and expand the cabin again; when a canopy needs to be erected in the circumference of the cabin, the covering plate 303 is removed, and then the long plate 301 or the short plate 302 in the direction where the canopy needs to be erected is slid, and the long plate 301 or the short plate 302 is slid to a position higher than the hinge between the mounting portion 51 and the rotating portion 52, and the rotating portion 52 is loosened. Nut 7 drives the rotating part 52 to rotate the long board 301 or the short board 302. After the long board 301 or the short board 302 rotates to be horizontal with the ground or tilted toward the ground at one end away from the cabin body 1, the rotating nut 7 is tightened to fix the long board 301 or the short board 302. Then, the lifting rod 8 on the long board 301 or the short board 302 is driven to slide, so that the rotating shaft 9 slides to the rotating mouth 11, and the lifting rod 8 is rotated by the rotating shaft 9 to make the lifting rod 8 abut against the cabin body 1 to complete the erection of the canopy; when two square cabins are needed, the expansion cabin 3 is disassembled from the cabin body 1, and the area where the square cabin needs to be installed is reassembled to form another square cabin. The sliding lifting rod 8 drives the covering plate 303 to slide, so that the square cabin formed separately by the expansion cabin 3 can be expanded. Example 2

An expansion hole 26 is provided on the side plate 102, and the expansion cabin 3 is inserted in the expansion hole 26. A side slide plate 27 is slidably provided on the side plate 102. The side slide plate 27 is embedded in the side plate 102 and is flush with the surface of the side plate 102. In this embodiment, the side slide plate 27 has two A driving spring 28 is arranged between the side slide plate 27 and the side plate 102, and the driving spring 28 drives the two side slide plates 27 to slide toward each other. Through the elastic force of the side spring, when the expansion cabin 3 is removed from the cabin body 1, the two side slide plates 27 abut against each other to close the expansion hole 26. A wedge-shaped surface begins to appear on the opposite side of the side slide plates 27. When the expansion cabin 3 is installed, the side slide plate 27 is driven to slide by abutting against the wedge-shaped surface, thereby opening the expansion hole 26 and allowing the expansion cabin 3 to be inserted into the cabin body 1; a baffle plate 29 is arranged on the bottom plate 101, and the baffle plate 29 is driven by the spring to abut against one end of the expansion cabin 3 inserted into the cabin body 1.
