[0042] Working principle: first, the support base 1 is carried to the edge position where the protective fence needs to be installed, and the support base 1 is stably fixed on the ground through the fixing foot 6.

[0043] When the height of the guardrail needs to be adjusted, the construction personnel rotates the adjusting wheel 405 located on the outer wall of the outer guardrail 2, which drives the rotation of the driving rod 401, and the second bevel gear 404 on the outer wall of the driving rod 401 rotates accordingly. Since the first bevel gear 403 and the second bevel gear 404 on the same side are meshed with each other, the rotation of the second bevel gear 404 will drive the rotation of the first bevel gear 403, and in turn drive the rotation of the lead screw 402 fixedly connected to the first bevel gear 403. The lead screw 402 cooperates with the internal thread groove inside the inner guardrail 3 to convert the rotation of the lead screw 402 into the lifting movement of the inner guardrail 3. The inner guardrail 3 slides in the sliding groove 201 inside the outer guardrail 2, which provides guidance for the lifting of the inner guardrail 3 and ensures that the inner guardrail 3 remains stable during the lifting process and does not sway or deviate. The construction personnel can easily adjust the height of the guardrail according to the actual construction scene requirements.

[0044] If the angle of the guardrail needs to be adjusted, the construction personnel lifts the stop block 507 upward, which compresses the spring 508 and makes the limiting rod 506 disengage from the limiting hole 504. At this time, the construction personnel can rotate the outer guardrail 2, which drives the rotation of the second disc 502 at the bottom relative to the first disc 501. The support shaft 503 at the bottom of the second disc 502 rotates inside the support seat 1, which provides stable support for the rotation of the second disc 502 and the outer guardrail 2, making the rotation process smoother. When the outer guardrail 2 is rotated to the appropriate angle, the construction personnel releases the stop block 507, and under the elastic force of the spring 508, the limiting rod 506 re-enters the corresponding limiting hole 504, thereby fixing the angle of the outer guardrail 2.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features.
