A T-shaped column 14 is slidably connected to the cylinder 11, and the front end stepped surface of the T-shaped column 14 is connected to the cylinder 11 via a tension spring and its rear end can be inserted into the corresponding positioning hole 13.

[0018] In order to facilitate the rotation of the rotating shaft 2 and to facilitate the patient to maintain a body position with the body leaning forward with the head slightly lowered, the head tilted back 30 degrees or the head tilted back 60 degrees, the front end of the rotating shaft 2 extends out of the support frame 1 and is fixed with a handwheel 15. The front side of the support frame 1 is provided with a plurality of limiting holes 16 with openings facing forward and distributed along the circumferential direction of the rotating shaft 2. The angle between every two adjacent limiting holes 16 is 30 degrees. The handwheel 15 is provided with a limiting rod 17 which can be moved forward and backward, and the rear end of the limiting rod 17 can be inserted into the corresponding limiting hole 16.

[0019] In order to enable the limit rod 17 to move forward and backward, a sliding groove in the forward and backward direction is opened on the handwheel 15, the limit rod 17 is slidably connected to the sliding groove and the front end is connected to the end of the sliding groove through a spring. The limit rod 17 is thin in the middle and thick at both ends. The connection between the thick and thin parts on the limit rod 17 is a conical surface, and the diameters of the opposite ends of the two conical surfaces are smaller than the diameters of the opposite ends. A pressure column 18 is slidably connected to the lower side of the handwheel 15, and the upper end of the pressure column 18 contacts the conical surface on the front side.

[0020] In order to facilitate the operation of the rotation angle of the hand wheel 15, the left side of the rear end of the limiting rod 17 is an inclined surface.

[0021] In order to better maintain the correct angle of the patient's head and increase the patient's comfort when using it, restraint belts are fixed on the front and rear sides of the baffle 7 respectively, and the free ends of the two restraint belts can be glued by Velcro, and a soft pad is provided on the upper surface of the support plate 4.

[0022] When the utility model is in use, the upper ends of the first swing rod 3 and the second swing rod 5 are set to be slightly tilted to the left, the plug post 9 is inserted into the clearance groove 8, and the box body 10 is set on the upper end of the chair backrest in the initial state; when the patient needs to do a nasal examination, the doctor first swings the baffle 7 forward 90 degrees, the baffle 7 swings forward around the pin axis, and the plug post 9 is removed from the clearance groove 8. The patient sits on the chair and adjusts the posture so that the neck enters the support frame 1, and the patient's waist fits the chair back, and the chin is placed on the cushion. The doctor swings the baffle 7 backward, and the plug post 9 is inserted into the clearance groove 8. At this time, the patient's body is in a position with a slightly forward tilt and a slightly lower head. The two restraint belts are glued to the patient's forehead with Velcro to slightly restrain the patient's head. The doctor examines the patient's nasal bottom, inferior turbinate, inferior nasal meatus and the front and lower part of the nasal septum;

[0023] When the patient's head needs to be tilted back 30 degrees, the doctor rotates the hand wheel 15 clockwise, and the inclined surface at the rear end of the limit rod 17 is squeezed by the limit groove, so that the limit rod 17 moves forward and squeezes the spring and its rear end escapes from the limit hole 16, and the hand wheel 15 drives the two first swing rods 3 to rotate clockwise via the rotating shaft 2, and the second swing rod 5 rotates rightward with the first swing rod 3 via the connecting rod 6, that is, the support plate 4 and the baffle plate 7 drive the patient's head to tilt back, and when the rotating shaft 2 rotates 30 degrees, the limit rod 17 resets backward under the action of the spring, and the rear end of the limit rod 17 is inserted into the limit hole 16. At this time, the patient's head tilts back 30 degrees and remains in the current state, which is convenient for the doctor to check the middle section of the nasal septum, the middle turbinate, the middle nasal meatus and the middle and posterior part of the olfactory fissure;

[0024] When the patient's head needs to be tilted back 60 degrees, the doctor rotates the hand wheel 15 clockwise, and the inclined surface at the rear end of the limit rod 17 is squeezed by the limit groove, so that the limit rod 17 moves forward and squeezes the spring and its rear end escapes from the limit hole 16, and the hand wheel 15 drives the two first swing rods 3 to rotate clockwise through the rotating shaft 2, and the second swing rod 5 rotates rightward with the first swing rod 3 through the connecting rod 6, that is, the support plate 4 and the baffle 7 drive the patient's head to tilt back, and when the rotating shaft 2 rotates 30 degrees, the limit rod 17 resets backward under the action of the spring, and the rear end of the limit rod 17 is inserted into the limit hole 16. At this time, the patient's head tilts back 60 degrees and remains in the current state, which is convenient for the doctor to observe the upper part of the nasal septum, the front end of the middle turbinate, the nasal hillock and the back of the olfactory fissure;

[0025] After the examination, the two restraint belts are removed, the baffle 7 is swung forward, the patient's neck is moved out of the support frame 1 and the patient stands up. Then the doctor presses the pressure column 18 inward, and the inner end of the pressure column 18 squeezes the conical surface of the limit rod 17, so that the limit rod 17 slides toward the side away from the limit hole 16 and compresses the spring. After the limit rod 17 is disengaged from the limit hole 16, the hand wheel 15 is turned counterclockwise. When the first swing arm 3 returns to its initial state, the hand wheel 15 is stopped, and the limit rod 17 is inserted into the limit hole 16 under the action of the spring, which is convenient for the next patient to use.

[0026] When the height of the support frame 1 needs to be adjusted according to the patient's height, the T-shaped column 14 is pulled forward and the tension spring is stretched. After the support frame 1 is moved upward to a suitable height, the T-shaped column 14 is released, and the rear end of the T-shaped column 14 is inserted into the corresponding positioning hole 13, so that the support frame 1 is maintained at the current height, which is convenient for the doctor to examine the patient's nasal cavity and increases the patient's comfort.
