[0002] As a textile material, cloth is increasingly used in industrial production, and its usage is increasing. In the past, cloth cutting and cutting were done manually, but the process efficiency of manual cloth cutting was low and the dimensional accuracy was poor, which could not meet the growing usage. With the development of industry, cloth cutting machines came into being; cloth cutting machines are machines for cutting cloth, which are mainly used for cutting a large number of small-sized samples or products;

[0003] In the existing cloth cutting machine, a guide rail that can move up and down is generally arranged on the workbench, and a cutting part is slidably connected to the guide rail. The guide rail is first lifted manually, and after a certain length of cloth is pulled out, the guide rail is lowered, and the cutting part is pushed to cut the cloth;

[0004] The Chinese patent application number CN202123060470.1 discloses a cloth cutting machine, including a workbench and a cutting tool. The workbench is provided with a clamp 1 for clamping the cloth, a clamp 2 for clamping the cloth, and a clamp 3 for clamping and bringing out the cloth. The clamp 1 includes two clamps 1 and a cylinder 1 for driving the two clamps 1 to clamp together. The edges of the two clamps 1 away from the roller are provided with a plurality of aligned grooves. The clamp 2 includes two clamps 2 and a cylinder 2 for driving the two clamps 2 to clamp together. The clamp 3 includes a moving frame, a driving mechanism for driving the moving frame to approach or move away from the clamp 1, two clamps 3, and a cylinder 3. The moving frame is slidably connected to the workbench. The cylinder 3 is fixedly connected to the moving frame and is used to drive the two clamps 2 to move in the opposite direction. The edges of the two clamps 3 close to the roller are provided with a plurality of aligned protrusions, and the protrusions and the grooves correspond one to one.
