[0002] Truss: A structure made up of rods connected to each other by hinges at both ends. The truss is a plane or spatial structure composed of straight rods and generally has triangular units. The truss rods mainly bear axial tension or pressure, so as to make full use of the strength of the material. When the span is large, it can save materials, reduce dead weight and increase rigidity compared to solid beams.

[0003] Trusses are used in many occasions, such as the construction of temporary stages. For this purpose, the trusses need to be installed. The prior art discloses a steel structure truss (authorization announcement number CN219411235U). This patented technology can facilitate the adjustment of the use position of the support rod through an adjustment mechanism, so that the construction height between the upper support plate and the lower support plate can be adjusted through the use of a connecting sleeve, thereby making the construction of the truss more convenient and practical, and the connecting mechanism is stable.

[0004] However, in actual use, this solution does not have any relevant fixing devices at the bottom of the truss, which makes it inconvenient to install and fix it in actual use, resulting in instability in actual use and failure to meet use needs. In order to solve the above problems, we have made improvements and proposed a steel structure truss. Utility Model Content
