[0002] Truss is widely used in stage building to support and install stage equipment, such as lights, fogger and sound, etc. Different trusses are used to build stages to meet the various needs of designers. However, stage design often requires a flexible and adjustable truss system, especially when building a sloping or angle-changing canopy. The current market method mainly relies on customizing corner trusses with fixed angles. Existing connecting trusses are mainly produced for specific angles, resulting in increased design and manufacturing costs, long manufacturing cycle, and inability to quickly respond to on-site needs. Second, fixed-angle trusses lack flexibility and cannot adapt to changing performance scenarios, which is not conducive to optimizing light and sound effects and limits performance results. There is an urgent need for a more flexible and easily adjustable truss connection method to meet the needs of quick installation, easy adjustment and cost control, thereby improving overall efficiency and performance quality.
