[0031] During the assembly process of the guardrail, the screw rod 206 is rotated, and the screw rod 206 pushes the threaded guide tube 205 to slide, thereby expanding the distance between the middle fixed rod 204 and the column tube 1. At this time, the outer sliding tube 202 slides along the inner sliding tube 201, and because the top of the movable rod 212 is connected by the spring 208, the spring 208 will automatically adjust the distance between the sliders 207 according to the distance between the middle fixed rod 204 and the column tube 1. The slider 207 slides in the inner sliding tube 201 and the outer sliding tube 202, so that the distance between the movable rods 212 is uniform again. The movable rod 212 slides along the protective hole 211, which assists in guiding and prevents pedestrians from passing through the enlarged gap. The length of the guardrail is adjusted according to actual needs, making installation more convenient while expanding the scope of application, further improving convenience.
