The base plate 1 has a first end and a second end along the length direction, the tracheal positioning assembly 2 comprises two positioning columns 21 arranged at intervals on the base plate 1 at positions close to the first end, each positioning column 21 is cylindrical, extends towards a direction away from the base plate 1, and is preferably arranged perpendicularly to the base plate 1. The spacing between the two positioning columns 21 is consistent with the spacing between the two air delivery holes 103 on the air pipe 100, and the shape and the size of the peripheral wall of the positioning columns 21 are matched with the shape and the size of the peripheral wall of the air pipe 100 at the positions of the air delivery holes 103. Therefore, when the air pipe 100 needs to be positioned, only the air delivery holes 103 of the air pipe 100 are aligned with the corresponding positioning columns 21 respectively, and the air is compressed from the side surfaces of the positioning columns 21 to the positioning columns 21, so that the peripheral wall of the positioning columns 21 and the air delivery holes 103 of the air pipe 100 are in close contact. By such positioning, not only the positioning of the air pipe 100 in the axial direction can be achieved, but also the angular deviation caused by the rotation of the air pipe 100 along its own axis can be avoided, so that the communication hole 102 is displaced from the first end of the main air intake pipe 200. That is, the positioning of the air tube 100 in the axial and circumferential directions is achieved by the cooperation of the cylindrical positioning post 21 and the air delivery hole 103 of the air tube 100.
