The limiting mechanism 8 can fix the strap 4 in the perforation groove 9; the limiting mechanism 8 includes a through hole 801, a limiting rod 802, a support spring 803, and a sliding groove 804. The sliding groove 804 is formed inside the mounting block 7 and communicates with the perforation groove 9, and the limiting rod 802 is slidably installed in the sliding groove 804. The support spring 803 is connected between the bottom of the sliding groove 804 and the limiting rod 802; a limiting groove 805 for the limiting rod 802 to insert is further formed on the mounting block 7. A through hole 801 for the limiting rod 802 to penetrate is formed on the inner side of the strap 4, and there are multiple through holes 801, and the multiple through holes 801 are equally spaced on the strap 4; a pull rod 10 extending outward through the mounting block 7 is further connected to the limiting rod 802, and there is a sliding groove on the mounting block 7 for the pull rod 10 to slide; the shape of the limiting rod 802 is semi-circular, the cross-section of the perforation groove 9 is arc-shaped, and the limiting groove 805 and the limiting rod 802 are fixed by clamping and locking; a filter screen 12 is installed inside the plug body 1.

[0023] During specific implementation, after directly inserting the nasal plug into the nose, it is necessary to limit the nasal plug in the patient's nose. Usually, an elastic cord is used to loop around the patient's head. However, the elasticity of the elastic cord is limited, and the head sizes of patients are different. The elastic cord may be too tight or too loose, reducing the comfort of the patient and easily causing the nasal plug to fall off. In the present utility model, by pulling the pull rod 10 to one side, the pull rod 10 drives the limiting rod 802 to slide in the sliding groove 804 and compress the support spring 803. Then, the limiting rod 802 disengages from the limiting groove 805 and the through hole 801. Then, the strap 4 is pulled to one side, so that the strap 4 slides to one side in the perforation groove 9, adjusts the strap 4 to an appropriate length, and then releases the pull rod 10, so that the support spring 803 rebounds to drive the limiting rod 802 to penetrate the through hole 801, and one end of the limiting rod 802 is inserted into the limiting groove 805 to limit the position of the strap 4.

[0025] In specific implementation, since the nostril diameters of different patients are different, it is necessary to replace the plug body 1 with different diameters. The plug body 1 can be rotated, and the external second thread 14 of the plug body 1 is engaged with the first thread 13, so that the plug body 1 is disengaged from the docking groove 15, and the plug body 1 can be quickly disassembled from the limit ring 6. Finally, through the docking grooves 15 with different diameters, the plug bodies 1 with different diameter sizes can be installed, improving the practicability of the nasal plug.

[0026] Working principle: When using the nasal plug with an anti-dropping structure, first, different diameter plug bodies 1 can be replaced through the cooperation of the first thread 13 and the second thread 14, and the selected plug body 1 is installed in the corresponding docking groove 15. Then, the plug body 1 is inserted into the nose, and the length of the strap 4 is adjusted through the limiting mechanism 8 to be more stably worn on the patient's head to limit the plug body 1 and prevent it from falling off. Finally, the oxygen is input through the air pipe 2 and is introduced into the plug body 1 through the diversion pipe 3, so that the oxygen enters the patient's nose. The oxygen is filtered by the filter screen 12 while passing through the plug body 1. The setting of the limiting mechanism 8 improves the stability and convenience of the nasal plug.
