Detailed Description

The invention will be further described with reference to specific embodiments. However, the present invention is not limited to the following examples.

As shown in figures 1 and 2, the universal groove bracket comprises a base plate 1 and a bracket parent body 2 with an arch wire groove A. The bracket parent body 2 can also be provided with a self-locking plate 4, and the self-locking form of the self-locking plate 4 is not limited in the embodiment. As shown in fig. 3, the working wing at the gingival end of the bracket parent body is provided with a rolling shaft hole 24, and as shown in fig. 4, a rolling shaft 25 is arranged in the rolling shaft hole 24. Correspondingly, as shown in fig. 7, the locking blind hole 41 is disposed on the locking plate 4 and is engaged with the roller 25. As shown in fig. 3, a sliding groove 26 for arranging a locking plate is further arranged on the working wing at the gingival end of the bracket parent body, and a slide way 27 and a slide way 28 are arranged on two sides of the sliding groove 26.
