The present invention provides a cutting unit which comprises a circular cutter chassis having a coupling aperture provided at the center thereof, a plurality of cutting members evenly distributed along the circumference of the cutter chassis each of which comprises a pedestal disposed at the circumference of the cutter chassis having a first inclined plane extended upward from the cutter chassis and a second inclined plane extended outward from the cutter chassis, and a cutter connected to the first inclined plane and being perpendicular to the first inclined, and having an inner blade element and an outer blade element relative to the center of the cutter chassis. The top surfaces of the inner blade element and the outer blade element are in a square-shape and positioned on a same plane. The cutting unit of the invention is of a better elasticity and the efficiency than that in the prior art, and difficult to be damaged.
