At the same time, the inner side of the adjusting head frame 4 is tightly fitted with the surface of the base 614, thereby fixing the base 614 on the two adjusting head frames 4.

[0053] Then install the clamping assembly 63. When installing, fit the outer shell 6331 with the outer side of the clamping plate 632, and then screw in the airbag 637 at one time. When screwing in the airbag 637, screw the screwed air pipe 639 on the airbag 637 through the through hole 638 and screw it into the threaded screw hole on the outer shell 6331 until the airbag 637 fits the surface of the clamping plate 632, and then clamp the clamping pad 631 on the airbag 637 so that each airbag 637 are all inserted into the corresponding sleeve holes 636, and then the two clamping sliders 634 are slid onto the slide rod 612, and then the adjustment component 62 is installed, and then the spiral push rod 622 is installed on the adjustment connecting plate 621. During installation, the convex ring 624 on the spiral push rod 622 is deformed and passed through the push hole until the push ring 623 fits with the push plate 635. The spiral push rod 622 is connected to the push plate 635 through the convex ring 624 and the push ring 623.

[0054] When fixing the patient's head, the screw push rod 622 is rotated to drive the clamping assembly 63 at the top of the screw push rod 622 until the clamping assembly 63 is in contact with the patient's temporal and sternocleidomastoid muscles, and then the external air pump is started to inflate the interior of the outer shell 6331. The air pressure inside the outer shell 6331 is used to inflate the interior of the airbag 637 through the threaded air tube 639 until the pressure sensor on the top of the airbag 637 detects a preset pressure, thereby closing the solenoid valve and stopping inflating the interior of the airbag 637. The two clamping assemblies 63 are used to fix and clamp the two sides of the patient's head, and then the angle of the head fixing device 6 is adjusted by the adjustment structure to make the patient's head at a comfortable angle.

[0055] When adjusting the rotation direction of the head frame 4, the slide card unit 5 is slid to the outermost side, and then the head frame 4 is rotated, thereby driving the steering card strip 43 inside the steering groove 41 to rotate. The rotating steering card strip 43 will squeeze the steering bar 33, thereby compressing and deforming the steering bar 33 until the steering bar 33 enters the gap between the other steering card strips 43, thereby realizing the rotation of the head frame 4 on the rotating adjustment rod 3. When the head frame 4 is rotated to a suitable angle, the slide card unit 5 is pushed, and the slide bar 52 and the slip ring 53 on the slide card unit 5 slide on the first slide groove 31 and the second slide groove 34 respectively, until the connecting strip 55 on the slide card unit 5 passes through the insertion hole 442 and is inserted into the corresponding steering strip 33. At the same time, the elastic strip 54 on the slide card unit 5 is inserted into the semicircular ring 341 on the side of the limit stop ring 441, and the steering bar 33 is inserted into the steering card strip 43 by the connecting strip 55 inserted into the steering bar 33, thereby fixing the head frame 4 on the rotating adjustment rod 3.
