After the block 15 is squeezed into the inner wall of the fixing groove 10, the hook head of the hook 12 can be just connected to the groove. A base 1 is provided at the bottom of the support rod 2, and a mounting hole is opened on the base 1. A mounting plate 4 is provided on the front side of the mesh 3, and a warning sign 5 is provided on the front side of the mounting plate 4. The edge of the warning sign 5 is coated with a reflective layer. The reflective layer can improve the visibility of the warning sign 5 under low light conditions, enhance the warning effect on workers, and improve the safety of the construction site. The front end of the buckle 11 can contact the support rod 2 so that the angle of the hook 12 will not be offset under the action of the compression spring 14.

[0020] like Figure 1 As shown, it also includes a photoelectric sensor 6 and an alarm 7. The photoelectric sensor 6 and the alarm 7 are provided on the front side of the mounting plate 4. The alarm 7 has a built-in controller, and the alarm 7 and the photoelectric sensor 6 are both connected to the controller by electrical signals. When the photoelectric sensor 6 detects that a worker is approaching the protective device, the alarm 7 can be triggered to sound an alarm to remind the worker to pay attention to safety, thereby effectively preventing potential construction hazards.
