The depth of the first support groove 15 is greater than the depth of the second support groove 16. When the whole structure needs to be moved, the base 4 and the support rod 2 are lifted and rotated so that the second support groove 16 is connected to the fixed rod 13 in the guide groove 12. At this time, the casters 8 will push out of the limiting groove 11. When the whole structure needs to be placed stably, the base 4 is rotated so that the first support groove 15 is connected to the fixed rod 13.

[0024] By rotating the adjusting threaded rod 7 in the adjusting cavity 6, the adjusting assembly 1 can be raised and lowered along the surface of the support rod 2. When installing the guardrail, simply place the guardrail on both sides of the adjusting assembly 1, and then, under the action of the adjusting threaded rod 7, the adjusting assembly 1 rises to engage with the sleeves on both sides of the guardrail.
