The invention discloses a four-star twisting cutter. The four-star twisting cutter comprises a sleeve; a chamfering groove is formed in the outer edge of the front side of the sleeve; a slot around the circle center of the sleeve is formed in the inner side of the chamfering groove; a butt joint groove is formed in the inner side of the slot; a shaft hole is formed in the center of the sleeve; spline grooves are formed around the shaft hole; a butt joint key is arranged on the outer edge of the back side of the sleeve; a butt joint ring is arranged on the inner side of the butt joint key; fourblades are arranged at the periphery of the sleeve; the butt joint key is corresponding to the butt joint groove; the butt joint ring is corresponding to the butt joint groove; edge sides of the blades are perpendicular to the circle center of the sleeve; and the back sides of the edges are tangential to the outer circle of the sleeve. The four-star twisting cutter has the following beneficial effects: cutters are tighter in bonding to prevent shredded meat from entering cutter gaps; the vertical fixation of the cutters is reinforced through the slot and the butt joint groove to further prevent vertical displacement of the cutters to bite the shredded meat; and the outer edge angles are chamfered to prevent hooking of the shredded meat, so that sanitation and safety are achieved, and thehuman health is guaranteed.
