Problems solved by technology

[0002] The metal cutting knives used in daily life often slip when cutting soft meat, which causes certain difficulties for raw meat processing
When cutting bone products with hard texture, the service life of the tool will be greatly shortened due to the increased force on the knife when chopping the bone

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.

Description

Technical field [0001] The invention belongs to the technical field of metal cutting appliances, and specifically relates to a bionic bone chopping knife. Background technique [0002] Metal cutting knives used in daily life often have slippery cuts when cutting softer meats, which causes certain difficulties in raw meat processing. When cutting hard bone products, the service life will be greatly shortened due to the increase of the force used on the knife when cutting the bone. Summary of the invention [0003] The purpose of the present invention is to provide a bone-chopping knife with a structure of imitating badger teeth, which can cut vegetables and meat, but also chop bones, save physical energy, can cope with various food materials, and solve many inconveniences in life. [0004] The bionic bone chopping knife of the present invention is composed of a handle 1, a knife body 2 and a knife edge 3. The handle 1 is fixed to the upper end of one side of the knife body 2, and th...
