[0002] Sofas have become a must-have piece of furniture in many homes. There are generally three types of sofas available on the market: low-back sofas, high-back sofas, and ordinary sofas somewhere in between. These three types of sofas can be further categorized as leather sofas, fabric sofas (actually fabric sofas), bentwood sofas, and rattan sofas.

[0003] Due to production needs, factories often encounter the situation where leather of different shapes needs to be cut from a piece of leather. This also makes it difficult for the pressing mechanism to press the pattern to be cut inch by inch along the cutting point, causing the cut pattern to shift when it is about to be finished, resulting in cutting failure.

[0007] By adopting the above technical solution, the laser cutting machine cuts the leather, and then the mounting plate moves with the material frame. Here, the movable end of the cylinder contracts, causing the pressure rope to slowly descend, and then press on the path traveled by the laser cutting machine. In this way, the pattern to be cut can be firmly pressed until the pattern cutting is completed, eliminating the possibility of displacement of the cut pattern and improving the cutting yield.

[0008] In a preferred example, the present invention can be further configured as follows: the conduit is arranged to be curved, and the inner wall is polished with sandpaper.

[0009] In a preferred example, the present invention can be further configured as follows: the diameter of the pressure rope is equal to half of the inner diameter of the catheter tube, and the pressure rope is made of metal material.
