The auxiliary pipeline 19 can move axially and radially along the main pipeline 1 through the movable connecting part 2 and the connecting rod, so that the air pipe joint of the auxiliary pipeline 19 can be connected to multiple hole positions, realizing connection with multiple hole positions arranged at equal angles, and the gas collection function is better improved.

[0030] Specifically, the movable connecting member 2 also includes a top movable sleeve 17 and a bottom movable sleeve 18 that are sleeved on the main pipe 1. A first connecting rod 21 is rotatably installed between the bottom movable sleeve 18 and the auxiliary pipe 19, and a second connecting rod 22 is rotatably installed between the top movable sleeve 17 and the first connecting rod 21. In this embodiment, the axial position of the auxiliary pipe 19 can be adjusted by simultaneously moving the top movable sleeve 17 and the bottom movable sleeve 18. The trachea joint installed on the top of the auxiliary pipe 19 can be close to the hole position and connected to the corresponding hole position. In addition, according to the position of the hole position, the top movable sleeve 17 or the bottom movable sleeve 18 is moved so that the angle between the first connecting rod 21 and the second connecting rod 22 changes, the distance between the auxiliary pipe 19 and the main pipe 1 can be adjusted, and the trachea joint installed on the top of the auxiliary pipe 19 can be coaxially aligned with the hole position to achieve a plug-in connection.

[0031] Furthermore, the secondary pipe 19 is provided with a rotating connecting member rotatably connected to the first connecting rod 21, and the rotating connecting member includes a rotating connecting shaft 23 transversely passed through the secondary pipe 19, and a rotating connecting seat 24 is installed at the end of the first connecting rod 21; one end of the first connecting rod 21 is rotatably connected to the rotating connecting shaft 23 of the secondary pipe 19 through the rotating connecting seat 24, so that the outer end of the first connecting rod 21 is rotatably connected to the secondary pipe 19, thereby realizing the distance adjustment between the secondary pipe 19 and the main pipe 1.

[0032] Furthermore, the rotating connecting seat 24 is provided with a movable groove, and the two side walls of the movable groove are provided with rotating connecting holes that are rotatably connected to the rotating connecting shaft 23; the rotating connecting seat 24 is rotatably connected to the rotating connecting shaft 23 of the auxiliary pipe 19 through the rotating connecting hole of the movable groove, thereby realizing the rotational connection between the outer end of the first connecting rod 21 and the auxiliary pipe 19, and realizing the distance adjustment between the auxiliary pipe 19 and the main pipe 1.

[0033] Furthermore, the outer wall of the top movable sleeve 17 is respectively formed with an outer wall seat 25, and the outer wall seat 25 is installed with an inner end connecting shaft 26.
