Abstract

The invention discloses a unidirectional-stitch sewing machine which comprises a rack, a sewing machine head comprising multiple parts like a sewing needle and a needle plate, and a transmission mechanism controlling the machine head to sew. Mounting holes and cloth passing grooves are formed in the needle plate, an alcove is formed in the needle plate, an annular sewing needle hole is formed in the alcove, one side of the needle plate is connected with an arc-shaped retaining plate which is positioned beside the sewing needle hole, and the retaining plate and the needle plate are in fixedly threaded connection through an inner-hexagonal screw. The retaining plate is additionally arranged beside the sewing machine needle, so that when the sewing machine starts to sew, only one sewing thread is needed to perform sewing with an annular stitch, huge convenience is brought to threading, the sewn stitch is attractive in appearance, and production efficiency is improved.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a sewing machine with one-way stitches.
