By setting the active cavity 43, the sliding disk 44, the pull rod 47 and the telescopic spring 48, the sliding disk 44 and the adjusting rod 41 can be horizontally slid into the active cavity 43 by pulling the pull rod 47. When the pull rod 47 stops being pulled, the telescopic spring 48 stretches and resets to push the sliding disk 44 and the adjusting rod 41 to move horizontally in the opposite direction, so that the adjusting rod 41 can be horizontally inserted into the limiting hole 42.

[0031] Two card slots 45 are provided in the movable cavity 43, and two card blocks 46 are fixedly provided on the outer wall of the sliding disk 44. The card blocks 46 are slidably provided in the card slots 45.

[0032] A pulling plate 49 is fixedly provided at the other end of the pull rod 47 . By providing the pulling plate 49 , medical staff or pediatric patients can pull the pull rod 47 to move horizontally by pulling the pulling plate 49 .

[0033] Two stretching bands 5 are fixedly provided at both ends of one of the connecting cloths 35, and one end of the stretching band 5 is fixedly provided with a No. 2 sub-Velcro 51. Two No. 2 female Velcro 52 are fixedly provided at both ends of the other connecting cloth 35. The No. 2 sub-Velcro 51 and the No. 2 female Velcro 52 are adhered to each other. By setting the stretching band 5, the No. 2 sub-Velcro 51 can have a certain expansion and contraction space. By setting the No. 2 sub-Velcro 51 and the No. 2 female Velcro 52, when the No. 2 sub-Velcro 51 is adhered to the No. 2 female Velcro 52, the two connecting cloths 35 can be fixed.

[0034] The telescopic assembly 6 includes a limiting bead 65 and a limiting groove 66. The outer wall of the limiting bead 65 is in active contact with the inner wall of the limiting groove 66. Two limiting beads 65 are provided, and a plurality of limiting grooves 66 are provided. A plurality of fixed rods 61 are fixedly provided on one of the fixing rings 1 and one of the adjusting rings 2. A plurality of movable rods 62 are fixedly provided on the other fixing ring 1 and the other adjusting ring 2. A cavity 611 is provided on the fixing rod 61. One end of the movable rod 62 is slidably provided in the cavity 611. By providing the cavity 611, the movable rod 62 can slide in the cavity 611. The plurality of limiting grooves 66 are equidistant. The inner wall of the cavity 611 is distributed, and by setting a limiting bead 65 and a limiting groove 66, when the limiting bead 65 enters the inside of the limiting groove 66, the adjusted movable rod 62 can be limited and fixed. Two telescopic grooves 63 are provided at one end of the movable rod 62. The inner walls of the two telescopic grooves 63 are fixedly provided with Z-shaped elastic parts 64. One end of the Z-shaped elastic part 64 is fixedly connected to the outer wall of the limiting bead 65. By setting the telescopic groove 63 and the Z-shaped elastic part 64, the limiting bead 65 contracts and squeezes the Z-shaped elastic part 64. After the contraction of the limiting bead 65, the limiting bead 65 can be contracted into the telescopic groove 63.

[0035] Working principle: When it is necessary to support and fix the neck of a pediatric patient, the medical staff first encloses the neck of the pediatric patient with the No. 1 airbag 31 and the No. 2 airbag 32. At this time, the upper area of the pediatric patient's neck contacts the upper No. 1 airbag 31 and the No. 2 airbag 32, and the lower area of the pediatric patient's neck contacts the lower No. 1 airbag 31 and the No. 2 airbag 32. Then, the four sealing plugs 34 are unplugged, and the inflation device is connected to the four air tubes 33 respectively. The two No. 1 airbags 31 and the two No. 2 airbags 32 are inflated through the inflation device and the four air tubes 33, so that the two No. 1 airbags 31 and the two No. 2 airbags 32 expand. At this time, the inflated two No. 1 airbags 31 and the two No. 2 airbags 32 cover the neck of the pediatric patient, support the neck area of the pediatric patient, and protect the neck area of the pediatric patient to prevent the neck skin from being abraded and the neck from being injured. When it is necessary to support and protect the necks of pediatric patients of different age groups, the medical staff first pulls the pulling plate 49, which causes the adjusting rod 41 to move horizontally into the movable cavity 43 through the pulling rod 47 and the sliding plate 44. At this time, the telescopic spring 48 is squeezed and contracted by the sliding plate 44, and then the adjusting ring 2 is pulled so that the different limiting holes 42 on the adjusting ring 2 correspond horizontally to the adjusting rod 41. Then, the pulling plate 49 is released, and the telescopic spring 48 is stretched and reset. The adjusting rod 41 is pushed horizontally into the corresponding limiting hole 42 through the sliding plate 44, and the size of the space between the adjusting ring 2 and the fixed ring 1 can be adjusted. At the same time, by pulling upward a fixing ring 1 and an adjusting ring 2 on the upper part, the movable rod 62 slides vertically upward in the cavity 611, and the height spacing between the two No. 1 air bags 31 and the two No. 2 air bags 32 is adjusted. In this process, under the action of the upward pulling force, the limiting bead 65 moves upward with the movable rod 62, and is squeezed and contracted into the telescopic groove 63, and the Z-shaped elastic member 64 contracts and deforms. When the upward pulling of a fixing ring 1 and an adjusting ring 2 is stopped, and the other limiting grooves 66 of the limiting bead 65 correspond horizontally, the Z-shaped elastic member 64 automatically extends and resets, and the limiting bead 65 can be pushed into the corresponding limiting groove 66 to limit and fix the adjusted movable rod 62, thereby conveniently realizing the adjustment of the space size between the two No. 1 air bags 31 and the two No. 2 air bags 32, thereby facilitating the neck support and protection of pediatric patients of different age groups, and improving the flexibility of the fixing device.
