A limiting plate 8 is fixedly connected to one end of the sliding column 7. A sliding tube 10 is fixedly connected to the other end of the sliding column 7;

[0023] Furthermore, a spring 9 is slidably sleeved on the surface of the sliding column 7 near the inner sides of the installation ring 6 and the sliding tube 10. The surface of the sliding tube 10 is slidably connected to the inner wall of the pipeline main body 1;

[0024] During operation, due to the structural design that a spring 9 is slidably sleeved on the surface of the sliding column 7 near the inner sides of the installation ring 6 and the sliding tube 10, the installation ring 6 supports the sliding tube 10 through the spring 9, and the sliding tube 10 has a supporting force for automatically sliding outwards.

[0025] Furthermore, the number of sleeves 3 is two, and adjacent sleeves 3 are fixedly connected through sleeve rings 4 and bolts 5;

[0026] During operation, due to the structural design that adjacent sleeves 3 are fixedly connected through sleeve rings 4 and bolts 5, it is convenient to disassemble and assemble the sleeves 3, improving the working efficiency of the user.

[0027] Furthermore, a ventilation port 11 is opened inside the sliding tube 10. Air dispersion holes 12 are equidistantly opened on the surface of the sliding tube 10. The shapes of adjacent sliding tubes 10 fit each other;

[0028] During operation, due to the structural design that the shapes of adjacent sliding tubes 10 fit each other, it is convenient to position between the two sliding tubes 10. Due to the structural design that air dispersion holes 12 are equidistantly opened on the surface of the sliding tube 10, it is convenient for the gas to flow evenly.

[0029] Furthermore, a ventilation chamber 13 is opened inside the pipeline main body 1, and the size of the ventilation chamber 13 is larger than that of the sliding tube 10;

[0030] During operation, due to the structural design that the size of the ventilation chamber 13 is larger than that of the sliding tube 10, after the sliding tube 10 slides inwards, the ventilation chamber 13 is used to connect and convey the gas.

[0031] Furthermore, a sealing gasket 14 is embedded inside the pipe body 1, and adjacent pipe bodies 1 are pressed tightly against each other through the sealing gasket 14;

[0032] During operation, due to the structural design that adjacent pipe bodies 1 are pressed tightly against each other through the sealing gasket 14, the sealing performance between the pipe bodies 1 is improved.

[0033] Working principle: First, the two sliding pipes 10 are snapped and aligned, and at the same time, the two sides of the pipe body 1 are squeezed. At this time, the sliding pipes 10 slide inward, and the gas in the ventilation chamber 13 enters the sliding pipes 10 through the air dispersion holes 12. The ventilation ports 11 of the two sliding pipes 10 are connected, and the gas is transmitted into another ventilation chamber 13. The two pipe bodies 1 are pressed tightly against each other, and the sealing performance of the device is improved through the sealing gasket 14. At the same time, the collar 4 is snapped onto the surface of the snap ring 2 and fixed by the bolt 5 passing through the collar 4. When the device needs to be disassembled, the collar 4 is removed by the bolt 5, and the pipe body 1 is split by sliding it to both sides. The sliding pipe 10 is automatically slid outward under the support of the spring 9, and the air dispersion hole 12 fits against the inner wall of the pipe body 1 to block the air flow.
