[0009] Furthermore, the fixing belt passes through each storage tube through each through hole.

[0010] Furthermore, a plurality of latching teeth are arranged on the crankset, each latching tooth is provided with a flat surface and an arc-shaped surface, and each crankset matches each latching slot.

[0011] Furthermore, each spring is in a compressed state.

[0012] Furthermore, the bottom of each winding rod is located at the middle of each lower sliding hole.

[0013] Furthermore, each storage tube is fixedly connected to the mask.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides an oxygen-absorbing mask with adjustable tightness, which has the following beneficial effects:

[0016] The oxygen mask with adjustable tightness can be tightened by rotating the winding rod, and the combination of the toothed disc and the slot can only rotate in one direction, so that the fixing belt can be tightened. Then, the turning handle is pressed to disengage the toothed disc from the slot, and the winding rod is rotated in the opposite direction to loosen the fixing belt. The device is convenient for adjusting the tightness of the fixing belt, so that the patient has a better sense of comfort. BRIEF DESCRIPTION OF THE DRAWINGS
