A plurality of frame plates 4 are connected between several extension tubes 3, the frame plate 4 and the adjustment plate 5 are connected, and the positioning holes of the support beam 2 and the adjustment plate 5 are connected through a positioning shaft 6.

[0031] The reinforcement assembly includes a fixed block 14, a guide plate 15, an arc hole 16, a positioning column 17, a limit plate 18 and a limit nut 19. A plurality of fixed blocks 14 are connected to a plurality of support tubes 1, and a plurality of limit plates 18 are connected to a plurality of support tubes 1. The fixed block 14 and the corresponding limit plate 18 are rotatably connected. A plurality of guide plates 15 are connected to the fixed block 14. The guide plate 15 is provided with an arc hole 16 corresponding to the positioning column 17. The limit plate 18 is connected to a plurality of positioning columns 17. The positioning columns 17 pass through the arc hole 16. The positioning columns 17 are connected to a plurality of limit nuts 19. The limit nuts 19 are distributed on both sides of the guide plate 15. It is preferred to provide a plurality of support tubes 1. The fixed blocks 14 and the limit plates 18 are respectively connected to different support tubes 1. The positioning holes on the adjustment plate 5 are preferably long strips. Holes, the support tube 1 and the extension tube 3 are preferably square tubes. The extension tube 3 is moved inside the support beam 2. After the positioning shaft 6 is removed, the adjustment plate 5 is moved to connect different positioning holes on the adjustment plate 5 with the positioning shaft 6. The support frame plate 4 and the adjustment plate 5 are to different heights, which are suitable for safety protection at different heights. When it is necessary to adjust the angle between the support tubes 1, the angle of the support tube 1 is adjusted by directly rotating the support tube 1, which is suitable for enclosing different areas. After the adjustment, the limit nut 19 is tightened. The limit nut 19 and the guide plate 15 cooperate to improve the connection force between the fixed block 14 and the limit plate 18, and improve the positioning effect between the fixed block 14 and the limit plate 18, which is beneficial to improve the positioning effect between the support tubes 1 and further improve the protection effect.
