Double-groove self-ligating bracket with anchorage effect

The invention discloses a double-groove self-ligating bracket with an anchorage effect, and relates to the technical field of self-ligating brackets, the double-groove self-ligating bracket comprises a clamping mechanism, a supporting mechanism is arranged at the lower end of the clamping mechanism, a fixing mechanism is arranged at the right end of the supporting mechanism, and a butt joint mechanism is arranged at the lower end of the supporting mechanism. The motor drives the movable plate to move upwards, then the movable plate drives the lifting block at the upper end of the connecting column to move upwards, and the orthodontic steel wire is fixed through the notch and the clamping groove in the inner side of the lifting block, so that the energy loss caused by excessive friction force on the orthodontic steel wire is reduced, and the orthodontic rate of the self-ligating bracket is increased; the main body part and the adsorption part of the self-ligating bracket are fixed through the bolt, so that the self-ligating bracket can be conveniently replaced when the device is locally damaged, the friction force between the tool and the bolt is improved through the thread head and the hexagonal groove, the bolt can be conveniently mounted and dismounted, and the service life of the device is prolonged.
