[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a staggered hollow truss structure, including a support column 1, two ends of the support column 1 are respectively welded with a fixing plate 2, the fixing plate 2 is provided with a fixing hole 3, a positioning tube 4 is welded on the support column 1, a fixing column 5 is movably installed between the positioning tubes 4, a connecting rod 9 is welded on the fixing column 5, one end of the connecting rod 9 is movably installed with a support tube 8, one end of the support tube 8 is welded with a reinforcing column 6, one end of the reinforcing column 6 is welded with a limiting column 7, the other end of the reinforcing column 6 is provided with a groove, one end of the limiting column 7 is movably installed in the inside of the groove, and after the limiting column 7 is installed in the groove, the positioning installation between the two reinforcing columns 6 is realized, which is convenient for the later combined installation.

[0021] In this embodiment, the support tube 8 is provided with an opening, and a fixing pin 10 is movably installed inside the opening. A cavity 11 is provided inside the support tube 8, and a connecting column 12 is movably installed inside the cavity 11. Limiting holes 14 are respectively provided on the connecting columns 12. One end of the fixing pin 10 is movably installed inside the limiting hole 14. A limiting seat 13 is welded to the bottom of the connecting column 12. A convex ring is fixed on the inner wall of the cavity 11, and the convex ring cooperates with the limiting seat 13.

One end of the positioning column 16 is welded to the fixing column 5, and the limiting seat 13 cooperates with the convex ring to avoid the influence caused by the connecting column 12 being pulled out from the inside of the cavity 11.

[0022] When the device is in use, first adjust the overall use form of the equipment according to the area supported by the support column 1. When it is necessary to expand the supporting area between the support columns 1, the support columns 1 on both sides are matched with each other, and the support columns 1 at the two top positions are moved first. The support columns 1 move upward, and the positioning tubes 4 on both sides move on the positioning columns 16. When the limiting seat 13 on the connecting column 12 contacts the convex ring inside the cavity 11, the connecting column 12 stops moving, and the support column 1 is limited. The fixing pin 10 is installed in the limiting hole 14 through the opening to fix the connecting column 12, and then the support columns on the left and right sides are pulled. Column 1, by gradually opening in four directions, the area used between the support columns 1 is increased, and after the increase, the support use in different situations is completed. When multiple devices are installed in combination, the limiting column 7 at one end of the reinforcing column 6 is inserted into the groove at the other end of the reinforcing column 6. The limiting column 7 cooperates with the groove to limit and fix the support columns 1. The fixing plates 2 are in contact with each other and are fixed in the fixing holes 3 by fixing bolts, thereby facilitating the combined installation and use of the equipment. The positioning tube 4 is welded to the support column 1 in a right-angled manner. The positioning tube 4 forms a multi-point support reinforcement for the support column 1.
