Moving cutter tool of crusher

The utility model provides a moving cutter tool of a crusher, which comprises a moving cutter body, a cutter head and a cutter head, the first face and the second face of the moving cutter body are each provided with at least one cutter shearing angle. The inclined arc groove is formed in the position of the cutting angle of the cutter and is inclined relative to the first surface and the second surface; two adjacent edges of the inclined arc groove and the cutting angle of the cutter respectively form two cutting edges with different heights and lengths; and when the rotor rotates for cutting, the two cutting edges with different heights on the first surface of the movable cutter body are in contact fit with a fixed cutter of the crusher in sequence, so that an object to be crushed is sheared. According to the movable cutter provided by the utility model, the shearing efficiency of the crusher is improved, and meanwhile, the equipment operation and maintenance cost is reduced. 本实用新型提供一种破碎机的动刀刀具，包括：动刀刀体，具有相互平
