[0023] The effect achieved by the entire embodiment 1 is that the staff pulls the pull rod 13, so that the pull rod 13 drives the movable plate 11 to move. At this time, the reset spring 9 is squeezed and begins to shrink, so that the movable plate 11 drives the limit rod 12 to move, canceling the limit on the installation column 4, and then pulls the installation column 4 upward, so that the installation column 4 drives the corrugated guard plate 7 to move upward. When the installation column 4 moves to the specified position, the pull rod 13 is released again. Under the action of the elastic force of the reset spring 9, the limit rod 12 is driven to squeeze into the limit groove 5 away from the end of the movable plate 11, so that the installation column 4 can be limited again, which is convenient for adjusting the height of the corrugated guard plate 7.

One end of the pull rod 13 away from the movable plate 11 movably passes through the fixed shell 8, and one end of the pull rod 13 away from the movable plate 11 is fixedly connected to the pull ring 16.

[0025] The effect achieved by the entire embodiment 2 is that, by providing a fixing mechanism 3 and rotating the bolt 302 through the threaded hole 301, the base plate 1 is conveniently fixed to the ground, thereby improving the stability of the column 2; and by providing an energy absorption mechanism 6, when a collision occurs, the corrugated guard plate 7 is subjected to force, so that the slide bar 603 is driven to slide toward the inside of the sleeve 601, and at the same time, the shock-absorbing spring 602 is squeezed and begins to shrink, and under the elastic force of the shock-absorbing spring 602 and the damping action of the damper 604, the impact energy can be absorbed, thereby playing a role in buffering and shock absorption; and when the operator pulls the installation column 4 upward, the installation column 4 drives the slider 15 to slide upward synchronously in the slide groove 14, thereby playing a role in limiting the installation column 4; and by providing a pull ring 16, it is convenient for the operator to pull the pull rod 13, thereby improving convenience.

[0026] Working principle: When in use, first fix the bottom plate 1 on the ground by rotating the bolt 302 through the threaded hole 301, so that the column 2 remains stable, and then the staff pulls the pull ring 16, so that the pull rod 13 drives the movable plate 11 to move, and at this time the reset spring 9 is squeezed and begins to shrink, so that the movable plate 11 drives the limit rod 12 to move, canceling the limit on the insertion column 4, and then pull the insertion column 4 upward, so that the insertion column 4 drives the corrugated guard plate 7 to move upward, and when the insertion column 4 moves to the specified position, the pull ring 16 is released. Under the elastic force of the reset spring 9, the end of the limit rod 12 away from the movable plate 11 is driven into the limit groove 5, so that the installation column 4 can be limited again, which is convenient for the operator to adjust the height of the corrugated guard plate 7. At the same time, when the corrugated guard plate 7 is collided, the corrugated guard plate 7 is subjected to force, which drives the sliding rod 603 to slide into the inside of the sleeve 601. At the same time, the shock-absorbing spring 602 is squeezed and begins to shrink. Under the elastic force of the shock-absorbing spring 602 and the damping action of the damper 604, the impact energy can be absorbed to play a role in buffering and shock reduction.
