Abstract
The invention discloses a bionic bone-chopping knife and belongs to the technical field of metal cutting appliances. A knife handle is fixedly connected at the upper end of one side of the knife body, and a blade is fixedly connected at the lower end of the knife body. The blade is provided with cutter teeth of characteristics of badger teeth, length H2 of a single cutter tooth is 2.6-7.5mm, width d of a large end of the single cutter tooth is 2-3mm, the ratio of the length H2 of the single cutter tooth and the width d of the single cutter tooth is 1.3:1-2.5:1, length L1 of the blade and the knife body are both 160-170 mm, length L2 of the knife handle is 140-150mm, width H1 of the knife body is 70-80mm, and thickness b of the knife body is 2-3mm. The single cutter tooth comprises a front curve face and a back curve face, and front faces of the cutter teeth and back faces of the cutter teeth are arranged in a stagger mode. The cutter teeth curve is provided with an expansion angle theta of 70 DEG to 0 DEG, and the expansion angle theta gradually decreases from the start point k of the cutter teeth to the end point M of the cutter teeth. Compared with an ordinary stainless steel knife, the bionic bone-chopping knife is longe in service life, labor-saving and highly-efficient.
