The second connection part cooperates with the first connection part to position the scale tube 20 in the CPAP generator 10. By connecting different first connection parts and second connection parts, the position of the scale tube 20 in the CPAP generator 10 is adjusted. The first connection part and the second connection part can be mutually cooperating threads, and the first connection part and the second connection part can also be the structure of a clamping block 111 and a clamping groove 112. The structures of the first connection part and the second connection part can be set according to actual use situations. For the scale tube adjustment and fixing device 100 of the CPAP generator of the present utility model, the connection between the scale tube 20 and the CPAP generator 10 is more stable, and the scale tube 20 can be adjusted in the CPAP generator 10 according to actual use needs. The structure is simple and the use is convenient.
[0035] Please refer to Figure 4 , in some alternative embodiments, a plurality of first connection parts are symmetrically arranged on both sides of the scale tube 20, and the plurality of first connection parts on the same side are equidistantly distributed along the axial direction of the scale tube 20. The equidistant distribution of the plurality of first connection parts enables the position of the scale tube 20 in the CPAP generator 10 to be adjusted by cooperating different first connection parts and second connection parts at different positions according to actual use requirements. Specifically, the first connection part can be a wedge-shaped block 211 with a wedge-shaped structure.
