[0024] In a specific embodiment, the fixing member further includes a plurality of fixing bolts 4 and a plurality of fixing nuts 5. The first fixing member 1 / the second fixing member 2 can be optimally designed to have at least one of a plurality of fixing holes 6. At least one end of the spring 3 is connected to the fixing bolt 4. The fixing bolt 4 passes through the fixing hole 6 and is fixed by being rotatably connected to the fixing nut 5. This design makes the stretching adjustment of the spring 3 more flexible and convenient, and the spring 3 can be adjusted more quickly according to the fixing effect of the guardrail 10, and also makes the fixing effect of the guardrail 10 more stable, thereby improving the safety and stability of the device during operation.

[0025] The construction guardrail clamping device is also designed to include a clamping component, which includes two symmetrically arranged clamping members 7, one end of each of the two clamping members 7 is rotatably connected to the first fixing member 1 to clamp guardrails 10 of different specifications.

[0026] The clamping member also includes a clamping bolt 8 and a clamping nut 9. The two clamping members 7 are respectively provided with mutually matching fastening holes.
