Abstract

The invention discloses bracket removing pliers which comprise plier handles hinged together. The front ends of the plier handles extend to form clamping arms. The upper surfaces of the clamping arms are inclined faces inclined downwards, and the lower surfaces of the clamping arms are inclined faces inclined upwards. Plier heads are arranged at the front ends of the clamping arms, and a V-shaped connecting structure is formed by the plier heads and the clamping arms. The projection of the appearance contours of the plier heads on the perpendicular face is internally arranged in the appearance contours of the plier handles. The plier heads are of a uniform section wedge-shaped structure with arc-shaped cutting edges. The arc-shaped cutting edges of the plier heads are arranged towards the inner side and protrude out of the inner side faces of the clamping arms. When the plier handles are completely closed, the preset clearance distance is kept between the arc-shaped cutting edges. The force applying angle perpendicular to a tooth face and a shearing removal mode adopted in the traditional technology are avoided, and operation flexibility is improved, so that the force applying angle and force are easy to control, the operation comfort level of orthodontic doctors is improved, and the fatigue feeling and pain feeling of a patient are relieved.
