[0025] For the embodiments, please refer to Figure 1 、 Figure 2 、 Figure 4 The present invention provides a technical solution:

[0026] An adjustable head and neck support pillow, comprising a support pillow body 1 and a support base 2. The support pillow body 1 is arranged on the top of the support base 2. The bottom of the support base 2 is fixedly connected with a bottom plate 3. Adjustable fixing components 4 are arranged in the inner cavity of the support base 2 and on the left and right sides of the support base 2. The adjustable fixing component 4 includes a rotating rod 401 arranged on the back of the support base 2. The rotating rod 401 penetrates through the back of the support base 2. One end of the rotating rod 401 extending into the interior of the support base 2 is fixedly connected with a driving gear 402. Two rotating rollers 404 are arranged in the inner cavity of the support base 2. The front and rear ends of the two rotating rollers 404 are respectively rotationally connected with the inner walls of the front and rear sides of the support base 2. Driven gears 403 are fixedly connected to the rear ends of the surfaces of the two rotating rollers 404. Pulling belts 405 are wound around the surfaces of the two rotating rollers 404. A cross bar 406 is arranged above the inner cavity of the support base 2. The two ends of the cross bar 406 are respectively fixedly connected with the inner walls of the left and right sides of the support base 2. Slide blocks 407 are symmetrically arranged on the left and right sides of the surface of the cross bar 406. L-shaped moving rods 409 are fixedly connected to the tops of the opposite sides of the two slide blocks 407. The other ends of the two L-shaped moving rods 409 both extend to the outside of the support base 2. Connecting plates 410 are fixedly connected to the tops of the opposite sides of the two L-shaped moving rods 409. Fixing plates 411 are fixedly connected to one ends of the two connecting plates 410 far away from the L-shaped moving rods 409. The two fixing plates 411 are arranged above the support pillow body 1.

[0027] As Figure 4 shown, the two driven gears 403 are respectively arranged on the left and right sides of the driving gear 402. The two driven gears 403 are both meshed and connected with the driving gear 402. The inner walls of the two slide blocks 407 are slidably connected with the surface of the cross bar 406. One ends of the two pulling belts 405 far away from the rotating rollers 404 are respectively fixedly connected with the bottoms of the two slide blocks 407. A return spring 408 is sleeved on the middle part of the surface of the cross bar 406. The left and right ends of the return spring 408 are respectively fixedly connected with the opposite sides of the two slide blocks 407.

[0028] As Figure 2 、 Figure 3 shown, connecting blocks 5 are fixedly connected to the four corners of the bottom of the support pillow body 1. Connecting grooves 7 are respectively formed at the four corners of the top of the support base 2. The four connecting blocks 5 respectively correspond to the four connecting grooves 7. The four connecting blocks 5 respectively extend into the interiors of the four clamping grooves 6. Clamping grooves 6 are respectively formed on the opposite sides of the left and right connecting blocks 5 far away from each other. Clamping rods 8 are respectively arranged at the front and rear ends on the left and right sides of the support base 2. One ends of the four clamping rods 8 respectively extend into the interiors of the four connecting grooves 7 and are clamped and connected with the clamping grooves 6. Expansion springs 9 are sleeved on the surfaces of the outer ends of the four clamping rods 8 located outside the connecting grooves 7.

[0029] The working process of the utility model: When in use, place the head and neck of the patient above the support pillow body 1. Rotate the driving gear 402 through the rotating rod 401. The driving gear 402 drives the two rotating rollers 404 to wind up the pulling belts 405 simultaneously by using the driven gears 403 on both sides. The two pulling belts 405 pull the sliding blocks 407 to approach each other and squeeze the return spring 408. The L-shaped moving rods 409 on both sides drive the two fixing plates 411 to move towards the middle to fix and limit the head of the patient. Adjust the positions of the two fixing plates 411 simultaneously, which is more time-saving and labor-saving. By pulling the clamping rod 8 outwards, the clamping rod 8 is separated from the inside of the clamping groove 6, and the support pillow body 1 can be disassembled for convenient cleaning and disinfection.
