By figure 1 to 6 and give, main part 1 including the left and right directions, left and right directions and opening groove 2 of stepping down up have been seted up on the main part 1, it has the fixed plate 3 of the shape of falling L respectively to step down the inslot 2 left and right sides, two fixed plate 3 bilateral symmetry, 3 lower extremes of fixed plate are equipped with swing plate 4, two swing plate 4 are constituteed and are fallen the splayed, be equipped with the bolster 5 that is located directly over groove 2 of stepping down on the main part 1, it just can reciprocate to be equipped with left and right directions in the groove 2 of stepping down removes frame 6, two swing plate 4 lower extremes are equipped with around the axial respectively and insert the slide bar 7 in removing frame 6.

In order to enable the movable frame 6 to move up and down, the abdicating groove 2 is connected with a front-back axial rotating shaft in a rotating mode, a cam 8 is coaxially arranged at the rear end of the rotating shaft, a sliding groove 9 with the same shape as the cam 8 is coaxially formed in the cam 8, and an inserting column 10 which is inserted into the sliding groove 9 and can slide in the sliding groove 9 is arranged on the movable frame 6.

In order to enable the movable frame 6 to only move in the up-and-down direction, sliding grooves 15 are respectively formed on the left side wall and the right side wall of the abdicating groove 2, and the left end and the right end of the movable frame 6 are respectively inserted into the sliding grooves 15 on the corresponding sides.

In order to facilitate the rotation of the rotating shaft, the front end of the rotating shaft penetrates through the main body 1 and is provided with a crank 11.

In order to limit the rotation of the rotating shaft, the front end of the main body 1 is provided with a threaded ring 12 coaxial with the rotating shaft, the front end of the threaded ring 12 is provided with a plurality of petal-shaped elastic plates 13 capable of contacting with the rotating shaft, and the threaded ring 12 is coaxially and threadedly connected with a threaded cylinder 14 capable of contacting with the elastic plates 13.

For fixing the main body 1, a suction cup 16 is provided at the lower end of the main body 1.

When the device is used, when the head of a patient needs to be fixed, a sucker 16 is in contact with a bed body and is pressed downwards, the device is fixed on the bed body under the action of the sucker 16, a crank 11 is rotated anticlockwise, the crank 11 drives a cam 8 to rotate through a rotating shaft, the cam 8 drives an insert column 10 to move upwards through a sliding groove 9, the insert column 10 drives two sliding rods 7 to move upwards through a moving frame 6, the two sliding rods 7 respectively drive the lower ends of swing plates 4 on the corresponding sides to swing upwards, the two swing plates 4 respectively drive fixed plates 3 on the corresponding sides to swing outwards, the crank 11 continues to rotate, the two fixed plates 3 continue to swing back to each other, and when the two swing plates 4 swing outwards to a certain position, the rotation of the crank 11 is stopped;

at the moment, the head of a patient is positioned on the pillow 5, the crank 11 is rotated clockwise, the crank 11 drives the cam 8 to rotate through the rotating shaft, the cam 8 drives the inserting column 10 to move downwards through the sliding groove 9, the inserting column 10 drives the two sliding rods 7 to move downwards through the moving frame 6, the two sliding rods 7 respectively drive the lower ends of the swinging plates 4 on the corresponding sides to swing downwards, the two swinging plates 4 respectively drive the fixed plates 3 on the corresponding sides to swing inwards, the two fixed plates 3 swing oppositely, the crank 11 continues to rotate, the two fixed plates 3 continue to swing oppositely, after the two swinging plates 4 swing to fix the head of the patient, the rotation of the rotating shaft can be limited at any time when the head of the patient is fixed, the swinging of the fixed plates 3 can be limited at any time, the fixed plates 3 are inverted L-shaped, so that the head size of the patient can be determined, the swing amplitude of the fixed plate 3 is adjusted at will, so that the practicability and the application range of the device are increased;

at the moment, the threaded cylinder 14 is rotated, the threaded cylinder 14 moves forwards along the threaded ring 12, the threaded cylinder 14 drives the elastic plate 13 to approach the rotating shaft, the threaded cylinder 14 continues to be rotated, the threaded cylinder 14 starts to extrude the elastic plate 13, when the threaded cylinder 14 moves forwards to a certain position, the elastic plate 13 clamps the rotating shaft and limits the rotation of the rotating shaft, the head of a patient is prevented from moving when the head of the patient is clamped, the image is not clear, the treatment cost of the patient is increased, and the working difficulty of medical staff is reduced;

after the examination of patient is accomplished, screw thread section of thick bamboo 14 is rotated in the opposite direction, make screw thread section of thick bamboo 14 move backward along threaded ring 12, no longer extrude elastic plate 13, no longer spacing is carried out to the rotation of countershaft this moment, anticlockwise rotation crank 11, crank 11 drives cam 8 through the pivot and rotates, cam 8 drives through sliding tray 9 and inserts post 10 and upwards moves, it drives two slide bars 7 rebound through removal frame 6 to insert post 10, two slide bars 7 drive its swing plate 4 lower extreme upswing that corresponds the side respectively, swing plate 4 upper end drives fixed plate 3 and outwards swings, two fixed plate 3 swing back to back mutually, no longer fix patient's head, patient's head moves away from pillow 5 can.
