The working process of the present invention is:

When the patient uses the present invention, if the patient's head needs to be lifted, the medical staff rotates the rotating disk of the first driving bevel gear 202, and the rotating disk drives the first driving bevel gear 202 and the second driving bevel gear 301 to rotate at the same time; The first driving bevel gear 202 simultaneously drives the two first driven bevel gears 203 to rotate, the two first driven bevel gears 203 respectively drive the first head support worm 204 to rotate, and the first head support worm 204 drives the first head The first head support worm wheel 205 drives the second head support worm 206 to rotate, the second head support worm 206 drives the second head support worm wheel 207 to rotate, and the second head support worm wheel 207 drives the third head support worm wheel 207 to rotate. The head support worm 208 rotates, the third head support worm 208 drives the two third head support worm wheels 209 to rotate at the same time, and the third head support worm wheel 209 drives the head support screw 210 to rotate. The same pair of support screws rotate in the same direction. The same, the rotation direction is the same, the support screw drives the head support slider 211 to move, the same pair of support sliders drives the first cylindrical rod to move horizontally, and the first cylindrical rod drives the two first runners to rotate on the first support rail 212 , the same pair of head support sliders 211 drives one end of the active support link 213 to move in a direction close to the first driving bevel gear 202 , and the end of the active support link 213 away from the head support slider 211 is connected to the driven support link 214 When one end of the active support link 213 moves in the direction close to the first driving bevel gear 202, one end of the driven support link 214 rotates on the fixed plate 1, and the driven support link 214 is away from the fixed plate 1. One end drives the second cylindrical rod to move, the second cylindrical rod drives the two second runners to rotate on the second support rail 215 on the head support plate 201, and the driven support link 214 drives the head support plate 201 to rotate on the fixed plate 1, and turn the head support plate 201 up to a certain angle.

When the head support plate 201 rotates, the second driving bevel gear 301 drives the second driven bevel gear to rotate, the second driven bevel gear drives the connecting shaft 302 to rotate, the connecting shaft 302 drives the rotating cylinder to rotate, and the rotating cylinder drives The first neck support gear 305 rotates, the first neck support gear 305 drives the second neck support worm 309 to rotate, the second neck support worm 309 drives the second neck support worm wheel 310 to rotate, and the second neck support worm wheel 310 Drive the rotating shaft on the support shell 5 to rotate, the rotating shaft drives the two neck support translation gears 311 to move on the rack of the fixed plate 1, and the six runners at the lower end of the support bottom plate roll on the fixed plate 1 to assist the support shell. The body 5 moves horizontally on the fixed plate 1 , and when the support casing 5 moves horizontally, the rotating sliding cylinder 304 is driven to slide on the connecting shaft 302 .

When the first neck support gear 305 of the present invention drives the second neck support worm 309 to rotate, the first neck support gear 305 drives the second neck support gear 306 to rotate, and the second neck support gear 306 drives the first neck support gear 306 to rotate. The neck support worm 307 rotates, the first neck support worm 307 drives the steering worm wheel to rotate, the steering worm wheel drives the steering worm to rotate, the steering worm drives the first neck support worm wheel 308 to rotate, and the first neck support worm wheel 308 drives the support shaft to rotate, The support shaft drives the neck support plate 312 to rotate.

After the head support plate 201 is rotated to an appropriate angle, the medical staff places the patient's head on the head support plate 201, and then uses the head fixing device 4 to fix the patient's head; the medical staff is using the present invention When the two head fixing devices 4 are installed, the medical staff rotates the rotating disk of the first fixed gear 401, the first fixed gear 401 drives the second fixed gear to rotate, the second fixed gear drives the first fixed worm 402 to rotate, and the first fixed worm 402 rotates. 402 drives the first fixed worm gear 403 to rotate, and the first fixed worm gear 403 drives the fixed rotating plate 404 to rotate. After the fixed rotating plate 404 rotates to an appropriate position, the medical staff stops rotating the first fixed gear 401; the fixed pressure plate cannot fix the patient's head. At the same time, the medical staff can continue to adjust the position of the fixed pressure plate, the medical staff rotates the rotating plate of the telescopic worm 406, the telescopic worm 406 simultaneously drives the two telescopic worm wheels 407 to rotate, and the two telescopic worm wheels 407 simultaneously drive the telescopic worm wheel 407. When the rod 408 rotates, the telescopic screw rod 408 is connected with the T-shaped plate 405 in rotation, and the telescopic screw rod 408 will drive the T-shaped plate 405 to slide and rise gradually along the fixed rotating plate 404. After the fixed pressure plate reaches the appropriate position, the medical staff stops rotating the telescopic worm 406; After the position of the fixed pressure plate reaches the proper position, the medical staff rotates the rotary plate of the fixed screw rod 411, the fixed screw rod 411 rotates on the fixed sleeve 409, and the fixed screw rod 411 rotates on the fixed sleeve 409 while the fixed telescopic cylinder 410 is fixed. With the limit pin sliding in the limit groove, the fixed telescopic cylinder 410 drives the fixed pressure plate to move toward the patient's head, and gradually fixes the patient's head.
