[0024] The effect achieved by the entire embodiment 1 is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in the subsequent actual use, a layer of sponge pad will be wrapped on the guide roller 115 to protect the guide roller 115. Then, when a collision occurs, the guide roller 115 can play a guiding role, and then the buffer pad 113 is used to achieve preliminary buffering, and then the characteristics of the damper 110 and the elasticity of the buffer spring 111 are used to reduce the impact force and reduce the probability of people getting injured.
[0025] Embodiment 2, as Figure 1-Figure 4 As shown, a reflector 104 is fixedly connected to the top center of the column 102, one end of the buffer spring 111 is fixedly connected to the outer surface of the damper 110, and the other end of the buffer spring 111 is fixedly connected to the rear outer surface of the buffer pad 113, and a plurality of evenly distributed guide rollers 115 are arranged on the inner surface of the frame 114, and a plurality of evenly distributed first bolts 108 are threadedly penetrated through the rear outer surface of the buffer pad 113, and a first threaded hole 109 is provided on the rear outer surface of the buffer pad 113 at the position of the first bolt 108, and the inner surface wall of the first threaded hole 109 is threadedly connected to the outer surface of the first bolt 108, and the surface thread of the first bolt 108 penetrates the surface of the frame 114. The second bolt 105 is threadedly penetrated on the rear outer surface of the slider 106, and a second threaded hole 107 is opened on the rear outer surface of the slider 106 at the position of the second bolt 105. The inner wall of the second threaded hole 107 is threadedly connected to the outer surface of the second bolt 105, and the surface thread of the second bolt 105 penetrates the surface of the column 102. The auxiliary structure 2 includes a fixed block 201, and a plug rod 203 is penetrated at the center of the top of the fixed block 201.

[0026] The effect achieved by the entire embodiment 2 is as follows: Figure 2 As shown, the frame 114 and the guide roller 115 are fixed to the buffer pad 113 by the first bolt 108. Therefore, if the guide roller 115 needs to be disassembled for maintenance or replacement later, the user can directly unscrew the first bolt 108 to make the frame 114 detachable, so that the user can inspect or replace the guide roller 115.

[0027] Working principle: First, the user inserts the insertion rod 203 into the corresponding circular hole 202. After multiple insertion rods 203 are inserted, the fixing operation of the base 101 is completed. Then the user manually slides the slider 106 up and down in the slide groove 103. When the slider 106 can slide up and down, it will drive the damper 110, the buffer spring 111, the connecting plate 112, the buffer pad 113, the frame 114 and the guide roller 115 to move, and finally the height of the guide roller 115 and the buffer pad 113 can be adjusted. After the adjustment is completed, the user can screw the second bolt 105 into the corresponding second threaded hole 107. Screwing in can fix the slider 106. When a collision occurs later, the guide roller 115 can play a guiding role, and then the buffer pad 113 can be used for preliminary buffering. By utilizing the characteristics of the damper 110 and the elasticity of the buffer spring 111, the impact force can be reduced to prevent the vehicle from being subjected to a strong reaction force, and the probability of people being injured can also be reduced.
