[0026] In the embodiment, the motor 11 drives the screw rod 12 to rotate, and the screw rod 12 drives the lower plate 13 to move up and down. The surface of the lower plate 13 is fixed with the bellows 9. The lower plate 13 drives the bellows 9 to expand and contract. When the bellows 9 is expanded, the gas in the side gas pipe 4 enters the bellows 9. When the bellows 9 is squeezed, the gas in the bellows 9 enters the front gas pipe 5 to supply the patient to breathe. The gas breathed by the patient returns to the side gas pipe 4 through the pipeline to form a gas circulation. When it is needed to adjust the gas pressure for the patient to breathe, the middle plate 7 is pulled upward. The middle plate 7 drives the connecting block 24 to move upward, and the connecting block 24 drives the upper frame 23 to move upward.

The upper block 6 is pushed downward, and the upper pipe 10 moves downward relative to the outer ring 15. The upper plate 8 is pushed downward to squeeze the bellows 9. The internal space of the bellows 9 changes. When the lower plate 13 squeezes the bellows 9, the remaining space in the bellows 9 becomes smaller, the pressure of the gas squeezed out of the bellows 9 changes, and the middle plate 7 is pushed downward after being moved to the appropriate position. The middle plate 7 drives the connecting block 24 to move downward, and the connecting block 24 drives the upper frame 23 to move downward. The upper frame 23 drives the seat plate 21 and the right plate 22 to move downward. The left plate 21 and the right plate 22 drive the upper rod 20 and the lower rod 19 to rotate. The upper rod 20 and the lower rod 19 drive the vertical plate 18 to move. The vertical plate 18 squeezes the tooth plate 17 to lock the outer ring 15. At this time, the upper pipe 10 cannot move up and down relative to the outer ring 15. When it is needed to adjust the internal space of the bellows 9 in a small range, the upper block 6 is rotated. The upper block 6 drives the outer ring 15 to rotate in the outer frame 16 through the upper pipe 10. The height of the outer ring 15 and the upper pipe 10 is further changed to change the degree of squeezing of the bellows 9.

[0027] The technical scope of the present application is not limited to the above description.
