When the receiving groove 61 corresponds to the locking groove 62, the first spring 64 will gradually return to the natural state and urge the locking block 63 to slide and engage in the locking groove 62, so that the two connecting seats 5 are locked and fixed together. , realizing the quick connection of two adjacent guardrail bodies 1.

When the connecting base 5 slides into the embedding cavity 51, the connecting base 5 will resist the end of the connecting rod 71 that extends into the embedded cavity 51. At this time, the connecting base 5 will push the connecting rod 71 to move, and the connecting rod 71 will move. 71 will drive the sealing plate 75 to slide in the channel 73, so that a negative pressure is formed inside the channel 73 between the sealing plate 75 and the airbag 74. The air in the airbag 74 will be replenished into the channel 73, and the volume of the airbag 74 will become smaller. The liquid level of the solution 41 in the rotating shell 4 will drop, and the counterweight plate 55 will drop and press on the liquid level of the solution 41 due to its own gravity, and the counterweight plate 55 will drive the connection base 5 to drop through the vertical plate 54, and the connection base 5 will The gear 53 is driven down through the connecting plate 52 and embedded into the gear housing 3. The gear 53 cannot rotate in the gear housing 3, thus achieving the fixation of the angle between two adjacent guardrail bodies 1.

To sum up, the worker only needs to adjust the angle between the two guardrail bodies 1 in advance and bring the two connecting seats 5 close to each other so that the connecting seats 5 are slid into the corresponding embedding cavities 51.
