Abstract

The invention discloses a sewing machine foot pressing and lifting device and belongs to the technical field of sewing machines. The sewing machine foot lifting device comprises a drive as well as a foot pressing mechanism, wherein the drive is fixedly arranged on one side of a sewing machine shell; the foot pressing mechanism comprises a pull rod base which is fixedly arranged on one side of thesewing machine shell and is used for adjusting a foot pressing height; an adjusting groove is formed in the pull rod base; a lifting connecting rod is arranged at the lower end part of the drive; a propping part and an adjusting part are respectively formed at two ends of the lifting connecting rod; the drive is propped against the propping part; an adjusting component is arranged between the adjusting part and the pull rod base; the adjusting component is hinged with the adjusting part; the adjusting component is matched with the adjusting groove and is clamped inside the adjusting groove; apressure regulator is arranged on one side of the adjusting part in a lifting manner; the pressure regulator is propped against the upper end part of the adjusting part. As the lifting height of a sewing machine foot pressing part is adjusted in a stepless manner, a common sewing machine can be transformed into an automatic thread cutting sewing machine conveniently.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, in particular to a sewing machine presser foot lifting device. Background technique [0002] At present, the interlock sewing machine: commonly known as the interlock sewing machine, uses two kinds of sutures, needle and shuttle, to make the shuttle thread form a single-sided covering chain stitch on the bottom of the sewing material, or add a covering line to the front of the sewing material to form a double-sided covering chain. Stitch, an industrial sewing machine that sews two or more layers of material. It is also an industrial sewing machine that can sew two or more layers of sewing materials. The covering line on the front is mainly for aesthetic decoration. Interlock sewing machine has greater elasticity due to the covered chain stitches sewn, which can be stretched when the garment is worn and restored after wearing, so it is suitable for sewing knitted garments that are worn n...
