Through adopting above-mentioned technical scheme, when spacing gasket 14 under the effect of spacing bolt 1, when the laminating is in the outer wall that supports slide bar 3, sliding sleeve 2 can be with the relative fixed of supporting slide bar 3 holding position under the frictional force effect of spacing gasket 14. After two solid fixed splint 6 and the laminating of patient's head both sides, solid fixed splint 6 can keep relative level under the effect of head, can't take place to rotate, consequently after solid fixed splint 6 is fixed with patient's head, the relative rotation between sliding sleeve 2 and the support slide bar 3 can not influence solid fixed splint 6's centre gripping effect.

Specifically, as shown in fig. 1 and 3, both ends of the adjusting threaded column 5 are rotatably connected with the fixed clamp plate 6 and the sliding sleeve 2 through rotating shafts respectively, two sections of the adjusting threaded column 5 are provided with threads, the two threads are symmetrical to each other, and the adjusting threaded column 5 is screwed with the adjusting threaded sleeve 4 through threads.

Through adopting above-mentioned technical scheme, through the thread line of adjusting mutual symmetry on the screw thread post 5 for when adjusting thread bush 4 and rotating, two adjust screw thread posts 5 and will move to the outside or inboard simultaneously, realized the regulation of interval between solid fixed splint 6 and the sliding sleeve 2.

Specifically, as shown in fig. 2, a limit bolt sleeve 15 screwed with the limit bolt 1 through a thread is arranged on the sliding sleeve 2, and a rotary table is fixedly connected to an extending end of the limit bolt 1.

Through adopting above-mentioned technical scheme, drive limit bolt 1 through the carousel and rotate, and limit bolt 1 will realize and the relative displacement between sliding sleeve 2 through the inside screw thread of limit bolt cover 15.

Specifically, as shown in fig. 1, the bottom of the supporting splint 8 is fixedly connected with an ear seat 12, and the bottom end of the ear seat 12 is rotatably connected with the connecting block 13 through a pin.

Through adopting above-mentioned technical scheme, can realize supporting splint 8 through ear seat 12 and connecting block 13 and carry out lever motion's function around the top of connecting block 13 for the top of supporting splint 8 can carry out the centre gripping to patient's head.

Specifically, as shown in fig. 1 and 4, the two connecting rods 9 are provided, the two connecting rods 9 are respectively located on the front side and the rear side of the supporting clamp plate 8, the two ends of the two connecting rods 9 are rotatably connected with the supporting clamp plate 8 through pin shafts, the connecting sleeve 10 is sleeved outside the connecting rods 9, and the connecting sleeve 10 is located on the outer side of the extension spring 16.

By adopting the technical scheme, the two support clamping plates 8 are provided with gaps through the two connecting rods 9, the bottom of each support clamping plate 8 has the tendency of moving towards the inner side through the extension spring 16, and then the top of each support clamping plate 8 has the tendency of opening.

Specifically, as shown in fig. 1, a projection is fixedly connected to the top end of the supporting sliding rod 3, and an anti-slip projection is disposed at the bottom of the bottom plate 11.

Through adopting above-mentioned technical scheme, through the setting of lug, prevent that sliding sleeve 2 from breaking away from supporting slide bar 3, increase the frictional force of bottom plate 11 and bed surface through anti-skidding lug, improve fixing device's stability.

One specific application of this embodiment is:

in use, the base plate 11 is placed on a bed surface for nursing a patient, and then the head of the patient is placed on the top of the base plate 11 and between the two supporting splints 8. Then the adjusting threaded sleeve 4 is rotated, so that the two adjusting threaded columns 5 simultaneously move towards two sides under the action of the threads, and the distance between the fixed clamping plate 6 and the supporting sliding rod 3 is increased. Until the fixed splint 6 contacts with the forehead of the patient, the head of the patient is fixed, and the adjusting range of the adjusting threaded column 5 is larger by adjusting the rotation of the threaded sleeve 4, so that the head fixing device can adapt to the head diameters of different patients, and the application range of the device is enlarged; two solid fixed splint 6 all pass through the slip of sliding sleeve 2 on supporting slide bar 3 in this device, realize around the centre of a circle pivoted function that supports slide bar 3 for can adjust solid fixed splint 6's position according to patient's wound position, avoid the wound position to fix, avoid causing the secondary damage. When the two supporting splints 8 support the head of the patient, the head of the patient is rested on the inner sides of the two supporting splints 8, so that the supporting splints 8 can perform lever motion by taking the connecting block 13 as a fulcrum, and in the motion process, the top end of the supporting splint 8 is close to the head of the patient, thereby realizing the fixation of the bottom of the skull of the patient by depending on the self weight of the skull of the patient. Two support splint 8 supports pass through connecting rod 9 and connect, and pass through 16 elastic connection of extension spring between two connecting rods 9 for the top of two support splint 8 is the opening form, is convenient for put into of head. And because the connecting rods 9 have the length, a gap exists between the two supporting splints 8, and if the bottom of the skull of the patient has a wound, the patient can rest through the gap between the two connecting rods 9 when the wound area is small. If the wound area is great, when the patient lies prone, the gap between two connecting rods 9 of facial accessible is breathed. Thereby the requirement that different positions of patient fix has been adapted to, has improved the application range of device, has reduced the use limitation of device.
