In order to enable the supporting plate 2 to move up and down, the left side and the right side of the seat 1 are respectively connected with an inverted L-shaped sliding plate 10 in a sliding mode, and the upper end of the sliding plate 10 is fixedly connected with the supporting plate 2.

In order to limit the sliding of the supporting plate 2, sliding grooves are respectively formed in the front side and the rear side of the seat 1, and the opposite ends of the two sliding plates 10 are respectively in threaded connection with a screw rod 11 which is in left-right axial direction and extends out of the sliding grooves.

In order to limit the sliding of the sliding rod 9, a limit groove is formed on the fixed plate 5, and an elastic plate 12 which can be inserted into the limit groove on the corresponding side of the sliding rod 9 is arranged on the sliding rod 9.

In order to shield the hands of the patient from light, the two swinging plates 6 are provided with shielding cloths 13 at opposite ends respectively.

In order to fix the shading cloth 13, the front side and the rear side of the back ends of the two swinging plates 6 are respectively provided with a buckle 14, and the free end of the shading cloth 13 is provided with a limiting rod 15 which can be matched with the buckle 14.

When the fixing device is used, when a puncture position of a patient needs to be fixed, the elastic plate 12 is pressed, the elastic plate 12 is made to be in contact with the sliding rod 9 on the corresponding side of the elastic plate, the sliding rod 9 is pulled forwards at the moment, the sliding rod 9 drives the elastic plate 12 to move forwards, the sliding rod 9 drives the rotating column 7 to rotate anticlockwise through the sliding groove 8, the rotating column 7 drives the swinging plate 6 to swing upwards through a pin shaft, the sliding rod 9 is pulled forwards continuously, the elastic plate 12 is not inserted into the limiting groove any more, the fixing plate 5 is not in contact with the swinging plate 6 any more, and the sliding rod 9 is not pulled any more when the swinging plate 6 swings upwards to a certain angle;

at the moment, the arm of the patient is placed on the fixed plate 5, the acupuncture point is positioned between the fixed plate 5 and the swinging plate 6, the screw rod 11 is rotated, the screw rod 11 does not extrude the seat 1 any more, the height of the sliding plate 10 is adjusted according to the requirement of the patient, when the height of the sliding plate 10 is required to be adjusted upwards, the sliding plate 10 is moved upwards, the sliding plate 10 drives the moving column 4 to move upwards through the supporting plate 2 and the sliding frame 3, the moving column 4 drives the fixed plate 5 to move upwards, when the fixed plate 5 is moved upwards to a position suitable for the patient, the sliding plate 10 is stopped to move, the screw rod 11 is rotated in the opposite direction, the screw rod 11 extrudes the acupuncture point again, and the sliding of the sliding plate 10 is limited;
