Among them, the connection column 4 is a square tube.

[0030] The connector 3 is a rectangular structure formed by six connecting plates, one end of the rectangular structure is fixedly connected to the connecting column 4 by welding, and the other end of the rectangular structure is plugged into the connecting block 1 .

[0031] like Figure 1 and Figure 2 As shown, a positioning hole 31 is formed on one side of the connector 3 facing the connector block 1, and the connector block 1 protrudes outwards toward both sides of the connector 3 and shrinks inwards to form positioning protrusions 11. The positioning protrusions 11 on both sides of the connector block 1 are respectively inserted into the positioning holes 31 of the two connectors 3, and the two connectors 3 are detachably connected through the connecting assembly 2. To facilitate the insertion of the connector 3 and the connector block 1, the positioning hole 31 and the positioning protrusion 11 are both circular, and the diameter of the positioning hole 31 is larger than the diameter of the positioning protrusion 11.

[0032] like Figure 1 As shown, the connection assembly 2 includes a threaded rod 21 and two connecting nuts 22. The threaded rod 21 passes through the positioning protrusion 11 and the connector 3.
