[0022] During use, the user inserts the protective strap 21 into the patient's nasal cavity, and fixes the device by tightly adhering the connecting ring 1 to the outer wing of the nostril. Then, the nasal endoscope can be inserted into the nasal cavity. At this time, the super-slippery coating 22 isolates the nasal endoscope from direct contact with the inner wall of the nasal cavity, greatly reducing discomfort that may be caused by friction or pressure. At the same time, the protective strap 21 is connected and fixed by the connecting strap 23, which improves the tightness of the connection of the protective strap 21 and prevents the bottom end of the protective strap 21 from shaking or shifting. After the tube is inserted, pull the connector 32 to pull the insertion rod 31 out of the groove 33. At the same time, the inner side of the insertion tube 34 is separated from the outer side of the connecting ring 1, so that the connecting ring 1 can be disassembled. Then, the protective strap 21 can be torn off to complete the disassembly.
