[0002] Leather is the animal skin that has been denatured and is not easily perishable after physical and chemical processing such as hair removal 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. When leather is processed and dried, it needs to be tightened and fully stretched before being placed in the drying device. Generally, the leather stretching machine fixes both ends of the leather directly for tightening. In this way, the non-tightened side of the leather is not flattened and misaligned. The existing leather stretching machines are not convenient for stretching and tightening the leather in multiple directions, and the method of directly pulling the ends of the leather is not convenient for effectively stretching all parts of the leather.
[0003] Therefore, a double-track rotating four-way mechanism for stretching cowhide sofa leather boards is needed to solve the problems that the existing leather stretching machines are not convenient for stretching in multiple directions and stretching efficiently in the prior art.

[0033] In summary: The height of the stretching roller 19 above the leather can be adjusted. The pulling force generated by the reciprocating downward pressing of the stretching roller 19 on the leather surface can achieve the effect of efficiently stretching the leather. The two stretching rollers 19 in the initial state can stretch the leather in the front-back direction, and after rotating the direction adjustment disc 9 to adjust the orientation of the stretching roller 19, the extrusion of the stretching roller 19 can stretch the leather in the left-right direction; during use, the positions and distances of the two stretching rollers 19 can be adjusted to adapt to the application scenarios of squeezing and stretching different parts of the leather.
