The outer periphery of the square tube 1 is provided with the sliding sleeve 2, and one side of the sliding sleeve 2 is rotatably connected with the splicing assembly 4.

[0030] The bottom of the sliding sleeve 2 is connected with a clamping strip 3 by welding, the top surface of the sliding sleeve 2 is provided with a clamping groove 201 corresponding to the clamping strip 3 , an opening 202 is provided in the sliding sleeve 2 , and the square tube 1 passes through the opening 202 .

[0031] When in use, the clamping strip 3, the clamping slot 201, the sliding sleeve 2 and the opening 202 facilitate the use of the sleeve sliding and plugging method to perform auxiliary docking during the docking operation of the end of the other rectangular tube 1, thereby improving the flexibility and stability of use, and also facilitating improving the safety of transportation and stacking operations.

[0032] In order to improve the stability of assembly and the flexibility of use, for example, Figure 2 , Figure 3 As shown, the utility model also includes that the splicing assembly 4 includes a rotating block 401, the top and bottom of the rotating block 401 are connected to the rotating shaft 402 by welding, and the rotating block 401 is rotatably connected to the sliding sleeve 2 through the rotating shaft 402, and the outer sleeve of the rotating shaft 402 is provided with a coil spring 403, one end of the coil spring 403 is connected to the rotating shaft 402 by welding, and the other end of the coil spring 403 is connected to the sliding sleeve 2 through a slot.

[0033] When in use, the rotating block 401 , the rotating shaft 402 , and the coil spring 403 can utilize elastic deformation and flipping to add an auxiliary splicing mechanism and improve the stability of the assembly of adjacent square tubes 1 .

[0034] For example, Figure 2 As shown, the utility model also includes that both sides of the opening 202 are connected with protrusions 203 by bolts, and the surface of the square tube 1 is provided with grooves 101 corresponding to the protrusions 203.

[0035] When in use, the sliding sleeve 2 is conveniently connected to the square tube 1 by sliding through the protrusion 203 and the groove 101 .

[0036] For example, Figure 3 As shown, the utility model also includes that the outer surface of the rotating block 401 is provided with a finger groove 404 .
