[0028] The connecting column 13 is symmetrically arranged on the left and right sides of the front and rear ends of the connecting rod 12 with the center of the connecting rod 12 as a reference, and a rotation connection is formed between the limit ring 1 and the connecting rod 12.

[0029] The limit plates 14 are fixedly installed on the top of the limit rings 1 on the left and right sides, and the installation positions of the limit plates 14 are staggered front and back. The length of the slide grooves 15 on both sides of the limit plate 14 above the limit ring 1 on the right side of the connecting rod 12 is half of the length of the limit plate 14.

[0030] The slider 16 and the limiting plate 14 are slidably connected, the airbag 18 is fixedly connected to the limiting rings 1 on the left and right sides, and the airbag 18 is connected to the air valve 110 through the connecting pipe 19 .

[0031] The connecting tube 19 is in an “L”-shaped structure. The connecting tube 19 passes through the limiting ring 1 on the left side of the connecting rod 12 and is connected to the air bag 18 inside the limiting ring 1 .

[0033] Specifically, the limiting ring 1 can limit the shape of the airbag 18, the connecting hole 11 can limit the position of the connecting column 13, the connecting rod 12 can facilitate the rotation connection between the limiting rings 1 on the left and right sides, the connecting column 13 can limit the position of the limiting ring 1, the limiting plate 14 can facilitate limiting the relative position between the limiting rings 1, the slide groove 15 can limit the moving direction of the slider 16, the slider 16 can facilitate the limiting ring 1 to maintain a contact state, the baffle 17 can facilitate driving the slider 16 to slide, the airbag 18 can apply pressure to the water hose, and the connecting pipe 19 can facilitate The airbag 18 is connected to the air valve 110. The ejector pin inside the air valve 110 can pierce the port of the gas cylinder 113 after the pull rope 111 is pulled, so that the gas inside the gas cylinder 113 enters the airbag 18 through the connecting tube 19, causing the airbag 18 to expand. The pull rope 111 can facilitate opening the air valve 110, and the T-shaped grip 112 can facilitate pulling the pull rope 111. The gas cylinder 113 can inflate the airbag 18. The connecting plate 114 can limit the relative position between the air valve 110 and the limiting ring 1, and the connecting frame 115 can limit the position of the gas cylinder 113.

When in use, the connecting rod 12 is located directly above the leakage. When the pull rope 111 is used to make the ejector pin of the gas valve 110 pierce the port of the gas cylinder 113, the compressed gas inside the gas cylinder 113 will enter the airbag 18 through the connecting pipe 19.

This method can reduce the operation during installation and complete the blocking of the water hose in a short time. The outer side surfaces of the airbag 18 are fixedly connected to the inner walls of the limit rings 1 on the left and right sides respectively. After the limit ring 1 wraps the water hose, it is necessary to make the center of the airbag 18 contact with the leakage point. Since the outer side surface of the airbag 18 is limited by the limit ring 1, after the gas inside the gas cylinder 113 enters the airbag 18, the airbag 18 will expand inwardly, thereby making the airbag 18 wrap the water hose, and the water hose is close to the airbag 18 through the air pressure inside the airbag 18 and the water pressure inside the water hose. This method can keep the pressure applied by the airbag 18 on the water hose uniform, so that the leaking part of the water hose is close to the inner wall of the airbag 18 to avoid leakage.
