[0002] The subway is a form of railway transportation, refers to the underground city rail transit system that operates mainly, namely "underground railway" or "underground iron". The underground railway is built in the city, and its construction method is greatly influenced by ground buildings, roads, urban traffic and capital conditions and other factors, and the tunnel needs to be supported and protected during construction to prevent tunnel collapse and ground subsidence and other conditions during construction, and reduce the influence on existing buildings.

[0003] A tunnel supporting device is disclosed in the Chinese utility model patent with publication number CN219795286U, which comprises: a top supporting mechanism and a side supporting mechanism, both of which are rotationally connected to make the tunnel supporting device have an unfolded state and a folded state, one of the top supporting mechanism and the side supporting mechanism is provided with a lock hook assembly, and the other is provided with a lock catch assembly; when the tunnel supporting device is in the unfolded state, the lock catch assembly is connected with the lock hook assembly; when the tunnel supporting device is in the folded state, the lock hook assembly is separated from the lock catch assembly. Therefore, when the tunnel supporting device needs to be used, it is directly placed in the unfolded state, and the top supporting mechanism and the side supporting mechanism are quickly and fixedly connected through the connection of the lock hook assembly and the lock catch assembly. When the tunnel supporting device needs to be stored or transported, the lock hook assembly can be separated from the lock catch assembly to quickly disassemble the top supporting mechanism and the side supporting mechanism, and then the tunnel supporting device is in the folded state. It can be seen that the tunnel supporting device is convenient to disassemble and assemble.

[0004] According to the related technology in the above, the inventor believes that the following defects exist: the device limits the hook body through the buckle body, so that the second connecting beam remains stable. When installing the second connecting beam, the worker needs to move the lower end of the hook body to the lower side of the buckle body. In actual use, due to the existence of certain tolerance between each connecting piece, the lower end of the hook body is difficult to move to the lower side of the buckle body after repeated use, so that the buckle body cannot limit the hook body, and the use experience is poor.
