[0002] Fabric, one of the three key elements of clothing, not only defines a garment's style and character but also directly influences its color and shape. Fabric processing requires sewing machines. Sewing, historically, referred to women engaged in textile, sewing, and embroidery work. The term "female worker" is more commonly used to refer to women engaged in textile, sewing, and embroidery work. During sewing, a tension adjustment device is used to stretch the fabric to prevent wrinkles that could affect the quality of the sewing process.

[0003] The prior art discloses an anti-wrinkle fabric composite forming device with application number 202310494489.1, which includes a tension balancing mechanism for adjusting the tension of the fabric being transmitted; the tension balancing mechanism includes: a tension roller movably mounted on a main body, the tension roller being used to transmit and pull the fabric outward; a cylinder assembly for pushing the tension roller to move, the cylinder assembly including a cylinder body and a cylinder rod; and a tension detector for detecting the tension roller. The pneumatic tension roller and the angle position meter are combined and connected to a composite machine with multi-frequency synchronous operation control. When the tension of the fabric is too small, the cylinder assembly is started to move the cylinder rod upward, and the cylinder rod drives the tension roller upward, and the tension roller pulls the fabric, thereby increasing the tension of the fabric. The tension of the fabric surface can always be kept basically balanced, so that the fabric surface always runs flat, wrinkles are prevented, and the product authenticity rate is improved. However, it is not convenient to clamp and fix one end of the fabric to be sewn and then tension pull and lay it flat, and the laying effect is generally good. Utility Model Content
