[0002] Leather is a denatured and non-perishable animal skin obtained through physical and chemical processes such as dehairing and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster, and feels comfortable. Some plant juices or mineral oils have certain tanning properties for leather. The raw leather is soaked in juice, making it more breathable and anti-corrosive, thus making the board have physical and chemical properties such as softness, tear resistance, and bending resistance.

[0003] During the leather cutting process, the entire leather needs to be cut at equal distances. Existing leather cutters mostly use the principle of pressing and cutting. Due to the high toughness of leather, pressing and cutting requires great force and slow speed, which greatly reduces the leather cutting speed and low processing efficiency. Utility Model Content
