[0059] During the movement of the pressing plate 35, the pressing plate 35 drives the top plate 4 of the side wall to move toward the center of the truss beam 11, so that the top plate 4 can move to the bottom of the truss beam 11, and the synchronization rod 421 on the top plate 4 is sliding, and the guide rod 43 on the synchronization rod 421 always slides along the lifting groove 431, and the lifting groove 431 is in an inclined state, so that the synchronization rod 421 is guided to move upward at this time, and the synchronization rod 421 pulls the top plate 4 to move upward, so that the top plate 4 supports the truss beam 11 at this time, improves the tightness of the connection of the truss beam 11, and ensures that the structure is more stable. In addition, during the upward movement of the top plate 4, the top plate 4 slides along the positioning groove 41, which plays a guiding role, and the synchronization rod 421 as a whole slides along the fixed seat 422, and the fixed block 42 at the bottom of the synchronization rod 421 drives the top plate 4 to move. In this process, the internal synchronization spring 423 is compressed, and the synchronization spring 423 is convenient for the later reset operation.

[0060] When the swing arm 33 rotates, the swing arm 33 will push the flip plate 5 to rotate. At this time, the flip plate 5 drives the card shaft 51 to rotate on the card seat 511, and the torsion spring on the card seat 511 is twisted synchronously, which is convenient for later reset. After the flip plate 5 rotates, the flip plate 5 drives the side plate 512 to rotate. At this time, the side plate 512 can be squeezed and fixed with the truss beam 11 of the side wall. At this time, the side plate 512 and the pressure plate 35 truss beam 11 are fixed as a whole, ensuring the stability of the connection between the truss beam 11 and the force is more uniform. When the flip plate 5 rotates, the flip plate 5 drives the swing arm 52 to rotate, and the swing arm 52 rotates the pressure roller 521 at the end to the side wall of the truss column 12. At this time, the pressure roller 521 and the active extrusion arm 231 cooperate together to complete the connection between the truss column 12 and the sliding cover 2, ensuring that the connection is tighter and the force is more uniform. Finally, the truss beam 11 and the truss column 12 can be tightly connected together, making the stability of the connection higher.
