[0025] This embodiment is further configured such that a pull ring is fixedly mounted on the upper end of the pull rod 10;

[0026] The pull ring facilitates the pull rod 10 to bear force.

[0027] The present embodiment is further configured as follows: the lifting assembly includes a lead screw 15, an inner cavity is provided in the support column 5 and the lower end is an open structure, guide grooves 16 are provided on the inner wall surfaces on both sides of the inner cavity, guide blocks 17 are slidably installed in the guide grooves 16, a moving rod 18 is fixedly installed between the guide blocks 17, the universal wheel 6 is installed at the lower end of the moving rod 18, the lead screw 15 is rotatably installed on the upper wall surface of the inner cavity and passes through the support column 5, a handle is fixedly installed on the upper end of the lead screw 15, a threaded groove is provided on the upper wall surface of the moving rod 18, and the lower end of the lead screw 15 is meshedly connected in the threaded groove;

At this time, the movable rod 18 moves along the guide groove 16 under the action of the guide block 17, so that the movable rod 18 drives the universal wheel 6 to recover and move out.

[0029] The present embodiment is further configured such that the plug-in assembly includes a fixing ring 19, the fixing ring 19 is fixedly mounted on the side wall surface of the support column 5 on the side wall surface of the guardrail box 1, a connecting plate 20 is fixedly mounted on the side wall surface of the support column 5 on the side wall surface of the guardrail plate 2, a plug rod 21 is fixedly mounted on the lower wall surface of the connecting plate 20, an external thread is provided at the lower end of the plug rod 21, a limiting nut 22 is screwed on the plug rod 21, and the plug rod 21 matches the fixing ring 19;

[0030] When two adjacent guardrails need to be butt-jointed, the insertion rod 21 is inserted into the fixing ring 19, and the limit nut 22 is screwed onto the insertion rod 21, thereby achieving the butt-jointing of the two adjacent guardrails, and the angle between the two adjacent guardrails can also be adjusted.

[0031] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0032] Embodiment: According to the attached drawings of the specification, the pull rod 10 is pulled, so that the pull rod 10 drives the limiting tooth 11 to separate from the rack 8, and the baffle 12 squeezes the spring 13. At this time, the guardrail plate 2 is pulled, so that the guardrail plate 2 moves along the path of the slide slot 3 under the action of the slide rod 4, and the guardrail plate 2 moves out of the guardrail box 1, thereby adjusting the total length of the guardrail plate 2 and the guardrail box 1. When the guardrail plate 2 needs to be limited, the pull rod 10 is released, and the spring 13 releases the elastic force to push the baffle 12. The baffle 12 drives the pull rod 10 to reset, so that the limiting tooth 11 contacts the rack 8, and the guardrail plate 2 is limited. By rotating the lead screw 15, since the lead screw 15 and the moving rod 18 are meshed and connected via a threaded groove, the lead screw 15 has a driving tendency to move the moving rod 18 when it rotates. At this time, the moving rod 18 moves along the guide groove 16 path under the action of the guide block 17, so that the moving rod 18 drives the universal wheel 6 to recover and move out. When two adjacent guardrails need to be docked, the insertion rod 21 is inserted into the fixing ring 19, and the limit nut 22 is screwed onto the insertion rod 21, so as to achieve the docking of the two adjacent guardrails, and the angle between the two adjacent guardrails can also be adjusted.
