[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. It can sew cotton, hemp, silk, wool, Man-made fibers and other fabrics and leather, plastic, paper and other products, the stitches are neat and beautiful, smooth and firm, the sewing speed is fast, and it is easy to use, and the sewing thread is an important factor connecting such products. In order to facilitate the sewing thread on the sewing machine In use, the sewing machine is fixedly provided with a thread frame for fixing the sewing coil at a specific position. On the one hand, the thread frame of this sewing machine is not convenient for the random placement of the sewing coil, and the overall height of the thread frame cannot be adjusted, and on the other hand , only one sewing machine coil can be used at a time, and the flexibility is not high, which is far from meeting the current people's requirements for this product. Therefore, how to design a sewing machine thread frame has become a problem we need to solve at present
