The second scissors handle 2 is inserted into the interlayer of the first scissors handle 1. The side surface of the second scissors handle 2 is connected to a limiting guide rod 3. A limiting guide groove 4 is provided on the surface of the first scissors handle 1 near the limiting guide rod 3. A first card slot 5 is provided on the surface of the first scissors handle 1. A second card slot 6 is provided on the surface of the second scissors handle 2. A first connecting block 7 is connected to the side surface of the second scissors handle 2. A second connecting block 8 is connected to the side surface of the first scissors handle 1. A spring bar 9 is connected between the first connecting block 7 and the second connecting block 8.

[0027] Among them, the first scissors handle 1 is slidably connected with the limiting guide groove 4 and the limiting guide rod 3, the width of the first card slot 5 is consistent with that of the second card slot 6, and an elastic telescopic structure is formed between the first connecting block 7 and the second connecting block 8 through the spring bar 9.

[0028] In addition, the ends of the first scissors handle 1 and the second scissors handle 2 are sleeved with a protective cover 10, the inner wall of the protective cover 10 is connected to a sealing ring 11, the end of the protective cover 10 is connected to a fixed spring piece 12, and the side surface of the second scissors handle 2 is provided with a fixing groove 13, the sealing ring 11 is made of rubber material, the fixing spring piece 12 and the fixing groove 13 are symmetrically arranged on both sides of the protective cover 10, the fixing spring piece 12 is made of beryllium copper, and a snap-fit ​​structure is formed between the fixing spring piece 12 and the fixing groove 13.

[0029] Working principle: When using the device of this technical solution, when trimming the patient's nose hair, the first scissors handle 1 and the second scissors handle 2 are inserted into the patient's nasal cavity. When the nose hair is stuck in the first card slot 5 and the second card slot 6, the second scissors handle 2 can be controlled by fingers to slide inside the first scissors handle 1, and the second scissors handle 2 can drive the limiting guide rod 3 to slide inside the limiting guide slot 4. At this time, the nose hair is clipped off by the misalignment of the first scissors handle 1 and the second scissors handle 2. In this process, the spring bar 9 can be compressed by the first connecting block 7. When the force disappears, the spring bar 9 can squeeze the first connecting block 7 by its own elastic force.
