AI Technical Summary
Technical Problem
Existing sewing machine presser feet are difficult to adapt to fabrics with seams, leading to fabric shifting, poor feed, jamming, and even the risk of needle breakage.
Method used
A sewing machine presser foot was designed, including a main presser foot, a secondary presser foot, a limiting component, and an elastic component. The height difference between the secondary presser foot and the main presser foot is adjusted by the limiting component to adapt to changes in the thickness of the ribs on the fabric and ensure a tight pressing effect.
Benefits of technology
It achieves stable fabric feeding and aesthetically pleasing stitches during sewing, reduces the risk of fabric shifting and jamming, and improves sewing quality.

Abstract
The application relates to the technical field of sewing machines, in particular to a sewing machine presser foot and a sewing machine. The sewing machine presser foot comprises a main presser foot, auxiliary presser feet and a limiting piece. Guide grooves are arranged on opposite sides of the main presser foot. The auxiliary presser feet are arranged on the opposite sides of the main presser foot, and each auxiliary presser foot can be inserted into the corresponding guide groove and is in sliding cooperation with the guide groove. The limiting piece is arranged on the same side of each auxiliary presser foot along the extension direction of the guide groove, and the limiting piece is adjustably connected to the main presser foot, so that the limiting piece can synchronously prevent the movement of each auxiliary presser foot along the extension direction of the guide groove. The sewing machine presser foot and the sewing machine provided by the application solve the problem that the existing sewing machine presser foot is difficult to adapt to the cloth with a bone position.
