Description

technical field [0001] This application proposes a multifunctional driving device for a sewing machine, specifically relating to the technical field of sewing machines. Background technique [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. The sewing machine can sew cotton, hemp, silk, wool , artificial fiber and other fabrics and leather, plastic, paper and other existing sewing devices. With the development of sewing machine technology, many manufacturers have technically improved the sewing action of the sewing machine, and some have proposed to use only one motor to control multiple sewing actions, which further improves the level of programmed control of the sewing machine and reduces the cost of the sewing machine. However, in actual production, the motor adopts a dual-head output power mode, which makes it difficult to install the...
