[0032] The utility model provides a guardrail. When in use, the guardrail frame 4 is placed between the two upright posts 1, and then the mounting plates 7 on both sides of the guardrail frame 4 are respectively placed on the fixed plates 8 on one side of the two upright posts 1 for support, and then the movable screw 14 is rotated by turning the rotating handle 2, so that the two threaded sliders 16 inside the hollow square plate 3 slide, thereby driving the corresponding movable plate 6 to slide down, thereby driving the positioning plug plate 15 to slide down, so that the positioning plug plate 15 slides into the positioning slot 17, so that the mounting plate 7 is limitedly installed between the movable plate 6 and the fixed plate 8, thereby completing the limited installation of the guardrail frame 4 between the two upright posts 1, and the installation can be completed by only turning the rotating handle 2, which is more convenient and improves the installation speed.

[0033] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model.
