Problems solved by technology

[0002] According to the mechanism used in the sewing machine, there are many mechanisms that move back and forth, including: the structure of the needle, the feeding teeth and the thread shuttle, all of which are in the form of a back and forth movement, or a back and forth rotary motion converted into a back and forth linear motion stroke; And the mechanism of these strokes, in the sewing machine, in order to avoid unnecessary loosening after use due to the adjustment, which will cause inaccurate movement, so there are few adjustable structures in the back and forth movement mechanism of the sewing machine. Or in the mechanism, there is an adjustable structure, the adjusted structure or its adjustment is not stable enough or it is easy to cause unnecessary displacement or loosening after adjustment, so there is still a need for improvement

Abstract

The invention discloses a motor-driven mechanism stroke start / end adjusting and positioning structure of a sewing machine. The structure comprises a fixing position, a positioning member and an adjusting device and is mainly characterized in that: the position of the center of a motor rotation member relative to a control shaft is adjusted by the adjusting device, so that a control member on the control shaft shifts and the mechanism at the other end of the control shaft also shifts to different stroke start / end points. Therefore, if the control member is driven by a motor, the mechanism at the other end of the control shaft acts on different stroke start / end points to achieve the aim of stroke adjustment so as to meet the practical needs.
