After the air is injected into the air pressure cabin 54, it will drive the air pressure rod 55 to push the support plate 56 to move to enhance the supporting effect of the fence, prevent the fence from collapsing and causing injuries to people. After the person gets down from the fence, the elastic support rod 62 will drive the upper fence 1 and the connecting plate 2 to recover. When the airbag 51 is restored to its original position, the airbag 51 will not be squeezed any more, the gas in the pressure chamber 54 will flow back to the inside of the airbag 51 through the air pipe 53, and the airbag 51 will resume its expanded state. The pressure rod 55 will drive the support plate 56 to return to its original position without the drive of gas, so that it can be used again next time. It is very practical. When people climb the fence, the upper fence 1 and the connecting plate 2 will be squeezed. The elastic support rod 62 will shrink after being squeezed and drive the upper fence 1 and the connecting plate 2 to descend. After the connecting plate 2 descends to a fixed position, the switch of the alarm 61 will be squeezed, and the alarm 61 will sound an alarm to notify the staff to deal with it, further enhancing the practicality of the entire device.
