The application discloses a lifting adjusting device for a cervical collar, which comprises a lower jaw plate, a rear pillow support, a support plate and an adjusting assembly. The lower jaw plate is used for supporting the lower jaw of a user. The rear pillow support is used for being attached to the rear neck and the pillow part of the user. The rear pillow support is movable to adjust the distance from the lower jaw plate, and is suitable for the neck circumference of the user. The support plate is used for being attached to the shoulder and the upper chest of the user, and is used as the reaction force fulcrum of the lower jaw plate. Two sets of adjusting assemblies are connected between the support plate and the lower jaw plate. The two sets of adjusting assemblies are used for synchronously adjusting and controlling the support height of the lower jaw plate, and are locked after the adjustment and control. The continuous and stepless fine adjustment is realized. The adjusting precision is much higher than that of the traditional mode. The synchronous work of the two sets of adjusting assemblies ensures the stability and the level of the lower jaw plate in the lifting process, and avoids the problem of uneven force on one side.

The invention relates to a platemaking method determined according to the relation between a neck root circumference plane and a three-dimensional space. The platemaking method comprises the following steps: S1, determining a plane with a left shoulder line, a right shoulder line, a front middle line and a rear middle line; s2, determining the position of the neck root girth on the plane; and S3, according to the first rotation center, the second rotation center and the shoulder inclination angle, a front collar arc line and a rear collar arc line during plate making are determined, and plate making shoulder inclination is determined. Compared with the prior art, the planar plate making method for determining the neck root circumference by combining the net neck circumference and the angle of the neck of the human body is adopted, and then the three-dimensional plate making method for determining the neck root circumference according to the thickness of the shoulders of the human body and the shoulder inclination angle is adopted, so that the planar neck root circumference obtained through plate making is matched with the neck root circumference of the human body; and the shoulders around the three-dimensional neck root circumference can be attached to the shoulders of a person. The platemaking method determined according to the relation between the neck root girth plane and the three-dimensional space is scientific, standard, high in precision and high in operability.
