Abstract
The invention provides a rotary blade. The rotary blade solves the problem that an existing rotary blade is short in service life. The novel rotary blade comprises a blade shank, a bended portion, a blade body and a cutting head, wherein a blade hole which is used for fixing is formed in the blade shank, and the bended portion is provided with a protrusion. The blade body comprises a blade back, a transition region and a cutting edge. According to the novel rotary blade, under the condition that the amount of metal is not increased, the bearing capacity of the rotary blade is increased through arrangement of a protruding reinforcing rib on the bended portion which bear larger force, the service life of the novel rotary blade is prolonged, and the novel rotary blade is simple in structure and suitable for commercialized popularization.
