The support band 2, the first positioning ring 22, the second positioning ring 23 and the winding rod 24 are provided with two groups, and the two groups of support band 2, the first positioning ring 22, the second positioning ring 23 and the winding rod 24 are symmetrically arranged with the center line of the support frame 1 as the axis of symmetry. By supporting the two groups of support bands 2, the stability of the support is increased, and the two groups of support bands 2 can be wound simultaneously by rotating the ratchet wheel 21 to adjust.

[0028] In a preferred embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the rear surface of the nose pad 3 is provided with an adjusting assembly, the adjusting assembly comprises a threaded rod 31 for driving the nose pad 3 to move, the rear end surface of the threaded rod 31 is fixedly connected with a second anti-skid disc, the second anti-skid disc can be rotated to drive the threaded rod 31 to rotate, the threaded rod 31 is rotationally connected to the rear surface of the nose pad 3, and the threaded rod 31 is through and threadedly connected to the front surface of the upper end of the support frame 1. By threadedly connecting the threaded rod 31 with the support frame 1, the second anti-skid disc can be rotated to drive the threaded rod 31 to rotate and drive the nose pad 3 to move. By changing the position of the nose pad 3, it can better adapt to the unique facial physiological structure of each patient, and can better fit the nose of the patient, thereby improving the stability and effectiveness of use.

[0029] In a preferred embodiment, as shown in Figure 2 ,Figure 4 and Figure 5 As shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4, the left side of the ratchet wheel 21 is fixedly connected with a first anti-skid disc for preventing sliding and driving the ratchet wheel 21 to rotate, the middle outer wall of the ratchet wheel 21 is provided with a clamping groove 29 in which a pawl 27 can slide to limit the reverse rotation of the ratchet wheel 21, the rear surface of the support frame 1 is slidingly connected with a guide rod 26 near the rear of the ratchet wheel 21 for supporting and driving the pawl 27 and the guide block 210 to move, the front surface of the guide rod 26 is fixedly connected with a guide block 210 for supporting and driving the pawl 27 to move, the front surface of the guide block 210 is fixedly connected with the pawl 27 which can slide into the clamping groove 29 to limit the reverse rotation of the ratchet wheel 21, and the rear surface of the guide rod 26 is fixedly connected with a disc for driving the guide rod 26 to move.

[0030] In a preferred embodiment, as shown in Figure 2 , Figure 4 and Figure 5 , the disc is elastically connected with the support frame 1 through a spring 25, the spring 25 is sleeved on the outer wall of the guide rod 26, one end of the spring 25 is fixedly connected with the front surface of the disc, and the other end of the spring 25 is fixedly connected with the rear surface of the support frame 1. By moving the disc, the guide rod 26, the guide block 210 and the pawl 27 are driven to move out of the clamping groove 29, thereby releasing the limitation on the ratchet wheel 21. At this time, the ratchet wheel 21 can rotate reversely, so that the support band 2 is loosened, and the support band 2 can be conveniently taken off from the patient's ear. The front end of the pawl 27 is provided with an inclined surface, and the pawl 27 is matched with the clamping groove 29.

[0031] Specifically, the front end of the pawl 27 is provided with an inclined surface. When the ratchet wheel 21 rotates, the clamping groove 29 is driven to rotate and press the inclined surface of the pawl 27, so that the pawl 27 moves outward to drive the guide rod 26 and the disc to move and stretch the spring 25. The reverse force of the stretched spring 25 can drive the disc to reset the guide rod 26, thereby driving the pawl 27 to reset and move into the clamping groove 29, reversely rotating the clamping groove 29 for limiting, so that the ratchet wheel 21 can only rotate in a specific direction, i.e. only driving the support band 2 to be wound and tightened, thereby effectively controlling and adjusting the tightness of the support band 2. The pawl 27 is clamped on the inner wall of the clamping groove 29, and the pawl 27 and the guide block 210 are slidingly connected on the inner wall of the support frame 1.

[0032] In a preferred embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the rear surface of the nose pad 3 is fixedly connected with a positioning rod 32 near the lower side of the threaded rod 31 for positioning and supporting the nose pad 3 to prevent the nose pad 3 from rotating, and the positioning rod 32 penetrates and slidingly connects with the upper end of the front surface of the support frame 1.

[0033] The use method is as follows:

[0034] In use, first, in use, two groups of support belts 2 are respectively sleeved on the ears of the patient, when it is needed to adjust the tightness of the support belts 2, the first anti-skid disc on the left side of the ratchet 21 is rotated, the first anti-skid disc drives the ratchet 21 to rotate, in the process of rotating the ratchet 21, the clamping groove 29 on the outer wall of the ratchet 21 rotates and extrudes the inclined surface of the pawl 27, because the inclined surface can make the pawl 27 move outward, the guide rod 26 and the disc behind it are moved, and then the spring 25 is stretched, when the ratchet 21 continuously rotates to wind the support belts 2, the spring 25 is stretched, under the action of the reverse force generated by the stretched spring 25, the disc drives the guide rod 26 to reset, so that the pawl 27 resets and moves into the clamping groove 29, the reverse rotation of the clamping groove 29 is limited, in this way, the ratchet 21 can only wind the support belts 2 to tighten, the tightness of the support belts 2 is adjusted, the device is stably fixed, the device and the oxygen delivery tube are prevented from falling, so that the patient can conveniently and comfortably perform oxygen delivery.

[0035] Then, for the position adjustment of the nose pad 3, the second anti-skid disc is rotated to drive the threaded rod 31 to rotate, because the threaded rod 31 is screw-connected with the support frame 1, and the nose pad 3 is rotationally connected with the threaded rod 31, so the rotation of the threaded rod 31 will drive the nose pad 3 to move, the positioning rod 32 on the rear surface of the nose pad 3 slides in the support frame 1, plays a positioning and supporting role, and prevents the nose pad 3 from rotating, through the change of the position of the nose pad 3, the nose pad 3 is better adapted to the size of the bridge of the nose of the patient and the physiological structure of the face, and the oxygen delivery tube can be aligned with the nostrils of the patient to perform oxygen delivery, and the applicability is better.

[0036] When it is needed to remove the device, the disc is moved to drive the guide rod 26, the guide block 210 and the pawl 27 to move, so that the pawl 27 slides out of the clamping groove 29, the limitation on the ratchet 21 is released, at this time, the ratchet 21 can be reversely rotated to loosen the support belts 2, that is, the support belts 2 can be conveniently removed from the ears of the patient, and the operation is relatively convenient.

[0037] Finally, it should be noted that: the above only describes preferred embodiments of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
