Description

technical field

[0001] The invention relates to the technical field of sewing machines, in particular to a novel sewing machine. 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 material.

[0003] Today's sewing machines generally have thread trimming, thread loosening and reverse sewing functions. The thread trimming and thread loosening functions are used together, and the reverse sewing functions operate independently of each other, which leads to the need for multiple driving sources. This will cause the volume of the sewing machine to increase, the structure will become complicated, and it will be inconvenient for later maintenance and maintenance. At the same time, the synchronization cannot be guaranteed, which will affect the sewing effect of the sewing machine. Moreover, the function of adjusting the pressure of the p...
