Two springs 8 are fixedly connected to the inner wall of the slide groove, and the other end of the spring 8 is fixedly connected to the pressure plate 6. An upper blocking plate 10 is provided on the outer wall of one side of the protective column 1. The upper blocking plate 10 and the lower blocking plate 2 are slidably connected to a plurality of protective rods 11. The upper blocking plate 10, the lower blocking plate 2 and the protective rods 11 can constitute the main component of the guardrail, which can facilitate the protection of the construction site. Snap-in components are provided on both sides of the protective column 1.
