Please refer to Figures 1 and 4. A positioning and adjustment mechanism is provided on one side of the traction mechanism, and the positioning and adjustment mechanism includes two shoulder support plates 201. The back sides of the two shoulder support plates 201 are provided with engaging grooves 202. One ends of the two shoulder support plates 201 are fixedly connected with fixing belts 203. One side of the two shoulder support plates 201 is rotatably connected with two threaded rods 205. One ends of the four threaded rods 205 are movably sleeved with threaded silicone rings 204. The engaging grooves 202 are engaged with the corresponding engaging plates 5. The middle part of the threaded rod 205 is threadedly connected with the inner wall of the corresponding threaded silicone ring 204. The threaded silicone ring 204 is fixedly embedded in one side of the inner wall of the convex groove 7. One end of the threaded rod 205 is threadedly connected with the other side of the inner wall of the convex groove 7. One side wall of the fixing belt 203 is fixedly connected with a Velcro sub-surface, and the back side of the shoulder support plate 201 is fixedly connected with a Velcro female surface.

Working principle: first, fix the neck traction belt 3 on the patient's neck to support the patient's neck, then fix the head support plate 101 on the bottom of the patient's head, pinch the threaded silicone sleeve 104, rotate the outer cylinder 103, adjust the distance between the inner rod 105 and the outer cylinder 103, so that the inner wall of the cushion 102 is completely fitted with the bottom side of the patient's head, then snap the shoulder support plate 201 onto the patient's shoulder, and fit the back plate 6 to the patient's back. Pinch the threaded silicone sleeves 104 on both sides, rotate the outer cylinder 103 on both sides, and adjust the distance between the inner rod 105 and the outer cylinder 103 on both sides, so that the shoulder support plate 201 is supported on the patient's shoulder position. In this way, the device is fixed to the patient's upper limb part, so that the patient's neck and head are both fixed, and the shoulder position provides support for the neck position, thereby increasing the traction and fixation effect;

The shoulder support plate 201 is fixed to the patient's shoulder position from above, so that the shoulder support plate 201 is placed obliquely on the patient's shoulder, and the bottom extends into the patient's armpit side, and the fixing belt 203 is rotated to make the fixing belt 203 pass through the patient's armpit position and come to the shoulder support plate 201 position behind the patient, and the fixing belt 203 is fixed to the back of the shoulder support plate 201, so that the device is fixed to the patient's shoulder, which provides a stronger support for the patient's neck. By rotating the threaded rod 205, the distance between the threaded rod 205 embedded in the convex groove 7 is changed, and the distance between the two shoulder support plates 201 is changed to make it suitable for patients of different height sizes. The threaded silicone ring 204 increases the friction between the threaded rod 205 and the convex groove 7, making the threaded rod 205 less likely to rotate. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
