[0025] The lifting column 7 also includes a slider 12 and a limit pin 8. The slider 12 is symmetrically distributed about the center point of the lifting column 7. The limit pin 8 is movably connected to the bottom of the lifting column 7 and is symmetrically distributed about the center point of the lifting column 7. The symmetrical spacing of the slider 12 is greater than the width of the fixed guardrail plate 3 and the movable guardrail plate 4. The slider 12 and the limit pin 8 provided on the lifting column 7 are used to guide the fixed guardrail plate 3 and the movable guardrail plate 4 when they are stored to avoid tilting when vertically plugged into the first pillar 1, and the limit pin 8 can support and fix the height of the lifting column 7 when the first pillar 1 and the lifting column 7 slide.

[0026] The fixed guardrail plate 3 and the movable guardrail plate 4 are threadedly connected with the fixing bolts 6. Fluorescent strips 5 are respectively provided on the outer surfaces of the fixed guardrail plate 3 and the movable guardrail plate 4. The head of the fixing bolt 6 fits inside the limit frame 9, and the threaded portion fits on the inner surface of the positioning groove 10 to slide. The fixing bolt 6 is threadedly connected to the fixed guardrail plate 3 or the movable guardrail plate 4. The fixed guardrail plate 3 and the movable guardrail plate 4 can be adjusted to be in a horizontal state by thread adjustment, and the angle of the fixed structure can be fine-tuned.

[0027] The first pillar 1, the second pillar 2 and one end of the lifting column 7 are respectively provided with a movable groove 14, and the movable groove 14 and the positioning groove 10 are slidably matched with the outer surface of one end of the fixing bolt 6.
