[0009] In some embodiments, two posts are symmetrically fixedly connected to the outer side of the fixed guardrail, and a fixing plate is fixed to the lower end of each of the two posts. Two fixing bolts are symmetrically arranged on the inner side of each of the two fixing plates.

[0010] In some embodiments, two pins are symmetrically fixed on one side of each of the two posts and the movable guardrail, and U-bolts are inserted into the inner side of each of the two adjacent pins.

[0011] In some embodiments, the outer ring support of the fixed guardrail and the movable guardrail is made of galvanized steel, and the inner mesh of the fixed guardrail and the movable guardrail is made of stainless steel.

[0012] In some embodiments, the fixed guardrail and the movable guardrail are not on the same horizontal plane.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] Firstly, this utility model, through the cooperation of guide rails and pulleys, allows the excavator to enter the construction area for construction by removing multiple U-bolts and sliding the movable guardrail along the outside of the guide rail to move it to the side of the fixed guardrail, thus ensuring the excavator's entry.
