When installing the guardrail plate 1 and the column 13, Insert the second positioning block 52 into the second positioning groove 51. At this time, the connecting column 310 enters the first through hole 21 and the second through hole 22, and the shell 31 enters the empty groove 23 and the third through hole 38. At this time, the first positioning block 4 is controlled to move by the handle 410, and the first positioning block 4 is completely fixed in the first positioning groove 41. By setting the first positioning block 4, the first positioning groove 41, the positioning plate 5, the second positioning groove 51, and the second positioning block 52, the effect of increasing the fixation between the guardrail plate 1 and the column 13 is achieved, so that the shell 31 will not shake in the empty groove 23, and the clamping plate 34 can fit more closely with the mounting plate 37.

[0029] The movable member 33 is slidably inserted with a plurality of evenly distributed limit rods 330, and the limit rods 330 are fixedly mounted to the inner wall of the shell 31; by providing the limit rods 330, the movable member 33 is limited, so that the movable member 33 can move stably.

[0030] The outer wall fixed sleeve of the connecting column 310 is provided with a sealing ring 63, and a side wall of the guardrail plate 1 away from the first positioning groove 41 is provided with a plurality of first sealing grooves 61 distributed in an array, and a side wall of the connecting plate 12 is provided with a symmetrically distributed second sealing groove 62, and the second sealing groove 62 is communicated with the second through hole 22, and the first sealing groove 61, the second sealing groove 62 and the sealing ring 63 are used in conjunction with each other; by providing the first sealing groove 61, the second sealing groove 62 and the sealing ring 63, the effect of sealing the second through hole 22 and the empty groove 23 is achieved to prevent rainwater from entering.

[0032] The number of the reflectors 11 is set to three; by setting the number of the reflectors 11 to three, a better effect of shielding the afterglow is achieved.

[0033] Working principle: First, the rotating rod 320 is controlled by the turning handle 340 to drive the screw rod 32 to rotate. The screw rod 32 drives the moving member 33 to move during the rotation process. The moving member 33 drives the card plate 34 to move during the movement process. During the movement of the card plate 34, one end of the card plate 34 rotates around the moving member 33. At this time, the spring 35 is deformed. The card plate 34 moves and one end of the card plate 34 rotates around the moving member 33. The end of the card plate 34 away from the moving member 33 enters the housing 31 through the through slot 36. When the end of the card plate 34 away from the moving member 33 completely enters the shell 31, the shell 31 and the connecting column 310 are pulled out from the empty slot 23, the first through hole 21, the second through hole 22, and the third through hole 38 to complete the disassembly between the guardrail plate 1 and the column 13. Subsequently, when installing the new guardrail plate 1, the connecting column 310 and the shell 31 are inserted into the first through hole 21, the second through hole 22, the empty slot 23, and the third through hole 38. Subsequently, the rotating rod 320 is controlled by the turning handle 340 to drive the screw 32 rotates, and the screw rod 32 drives the moving member 33 to move during the rotation process, and the moving member 33 drives the card plate 34 to move. When the card plate 34 is completely moved to the through groove 36, the spring 35 is deformed. Under the action of the deformation force of the spring 35, one end of the card plate 34 rotates around the moving member 33. During the rotation of the end of the card plate 34 close to the moving member 33, the end of the card plate 34 away from the moving member 33 moves to the outside of the housing 31 through the through groove 36. When the end of the card plate 34 away from the moving member 33 is tightly attached to the mounting plate 37, When the guardrail plate 1 and the column 13 are closed, the installation between the guardrail plate 1 and the column 13 is completed. By setting the first through hole 21, the second through hole 22, the empty slot 23, the shell 31, the screw 32, the moving part 33, the clamping plate 34, the spring 35, the mounting plate 37, the third through hole 38, and the connecting column 310, the installation and disassembly between the guardrail plate 1 and the column 13 can be facilitated, and the situation that the screws are rusted when the guardrail plate 1 and the column 13 are fixed with screws is avoided, and the situation that it is inconvenient for maintenance personnel to replace the guardrail plate is avoided;

[0034] Subsequently, when installing the guardrail plate 1 and the column 13, the second positioning block 52 is inserted into the second positioning groove 51. At this time, the connecting column 310 enters the first through hole 21 and the second through hole 22, and the shell 31 enters the empty groove 23 and the third through hole 38. At this time, the first positioning block 4 is controlled to move by the handle 410, and the first positioning block 4 is completely fixed in the first positioning groove 41. By setting the first positioning block 4, the first positioning groove 41, the positioning plate 5, the second positioning groove 51, and the second positioning block 52, the effect of increasing the fixation between the guardrail plate 1 and the column 13 is achieved, so that the shell 31 will not shake in the empty groove 23, and the clamping plate 34 can fit more closely with the mounting plate 37.
