Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

As shown in fig. 1 and 2, the utility model provides a tooth-pushing and grinding backward device, which comprises a bracket 1, a steel wire 2, a push spring 3 and a compression spring 4. The bracket 1 is provided with a plurality of brackets which are connected in series in sequence through steel wires 2 and fixed on the molar to be pushed by the bracket 1. Wherein, the size and the shape of the bracket 1 are selected according to the condition of the tooth. The push spring 3 is sleeved on the steel wire 2, the steel wire 2 between two adjacent brackets 1 is taken as a backward push section, and the push spring 3 is arranged on each backward push section respectively. The compression spring piece 4 is connected to the steel wire 2 at the rear pushing section, the compression spring piece 4 is located on the front side of the pushing spring 3, and teeth on the rear side of the pushing spring 3 are pushed backwards after the pushing spring 3 receives the compression force of the compression spring piece 4. Wherein, pressure spring spare 4 is connected for dismantling with steel wire 2, is both ends open-ended columnar structure including pressure spring spare 4, has seted up along the length direction of pressure spring spare 4 on the outer wall of pressure spring spare 4 and has put into mouth 41, and the both ends of putting into mouth 41 extend to the tip that pressure spring spare 4 corresponds the side respectively to in with pressure spring spare 4 through putting into mouth 41 cover on steel wire 2. Based on the detachable structure of the pressure spring piece 4, the pressure spring piece 4 is sequentially assembled on each backward pushing section from inside to outside, specifically, in the fixed correction, the pushing spring 3 is assembled at one time, and then in the re-diagnosis, the position of the pressure spring piece 4 is periodically changed according to the molar to be backward pushed. Preferably, the inner edge of the inlet 41 of the pressure spring 4 is rounded to avoid the damage of the pressure spring 4 to teeth or oral cavity. In addition, the compression amount of the push spring 3 can be accurately controlled by arranging the compression spring pieces 4 with different sizes.

The embodiment of the utility model provides a support groove 1 through combining traditional unscrambler, steel wire 2 and push away spring 3, will need to push away the position of molar, all adorn and push away spring 3, get two adjacent steel wire 2 of holding between the groove 1 promptly and push away the section for the back, and be provided with respectively on every back pushes away the section and push away spring 3, utilize the setting of compression spring spare 4, by pushing away spring 3 behind the compressive force that receives compression spring spare 4, will push away the molar back-push of 3 rear sides of spring, thereby in fixed the rescue, it is disposable to pushing away spring 3 assembly, only need regularly change compression spring spare 4 the position can, need not regularly to tear open the silk, trade and push away operations such as spring 3, convenient operation, and the compression volume that accurate control pushed away the spring.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
