Angle adjustable cutting apparatus

The utility model relates to a cutting apparatus with adjustable angles. The tip of a V-shaped groove is used as a center by a concentric circle principle. A movably fixed point of an electric motor is surrounded on a plurality of concentric circumferential tracks. Thus, the utility model achieves the principle that the center is not changed when the cutting angle is changed, the surface (and the side surface) of plate material is cut into a V-shaped groove (sloped edge) with different included angles from 60 DEG to 135 DEG by fast adjusting the cutting angles. The plate material is folded to form a box body of a special shape. The utility model has the advantages of simple structure, convenient operation, durability and high precision.
