Rotate the first rotating block 5. The first rotating block 5 drives the first lead screw 4 on the upper side wall to rotate. The first lead screw 4 drives the internally threaded ring 12 threadedly connected to the rod wall to move upward. The internally threaded ring 12 drives the bracket 13, the first anti-collision guardrail template 10 and the second anti-collision guardrail template 11 on the side wall to move upward, facilitating the adjustment of the support height. When the support area of the first anti-collision guardrail template 10 is insufficient, the second anti-collision guardrail template 11 can be installed and connected at both ends through the connecting mechanism, thereby increasing the support and protection area.
