AI Technical Summary
The traditional presser foot has a fixed distance from the needle drop position of the sewing machine and cannot be adjusted. As a result, different specifications of presser feet need to be replaced when sewing different margins. This operation is cumbersome and it is difficult to control the alignment of the ribbon and the base fabric.
A presser foot with adjustable sewing margin is designed, which includes a presser plate assembly, a movable edge retainer and a fastener. The position of the presser foot is adjusted and fixed through the combination of margin adjustment holes and positioning holes, providing a guiding and positioning function for the webbing.
There is no need to change presser feet of different specifications. It can automatically adjust the position of the ribbon and the base fabric when sewing different margins, simplifying the operation and improving sewing efficiency and accuracy.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textiles, in particular to a presser foot with adjustable sewing margins. Background Art
[0002] A sewing machine generally consists of four parts: the machine head, the base, the transmission, and accessories. The machine head is the primary component of the machine, comprising four mechanisms: the material insertion, thread hooking, thread take-up, and material feeding, along with auxiliary mechanisms such as the thread winding, material pressing, and material removal. These mechanisms coordinate their movements in a coordinated, cyclical manner to sew the material together. The presser foot is an essential component for both pressing and feeding the material. During sewing, the presser foot works in conjunction with the teeth on the feed dogs to move the material forward and hold it in place, preventing wrinkles and bulging. It also collaborates with the needle and other mechanisms to form the seam and ensure a perfect seam.
[0003] The traditional presser foot includes a mounting base and a presser foot plate. The mounting base is fixed to the presser foot rod of the sewing machine by a fixing screw, and the presser foot plate is connected to the mounting base by a connecting shaft. There is a needle hole on the presser foot plate. Once the existing presser foot is fixed to the presser foot rod, the distance between the presser foot plate and the needle drop position of the sewing machine is fixed and cannot be adjusted, that is, one presser foot can only be used to sew one margin, and the margin refers to the distance from the needle drop position to the side wall of the presser foot. When sewing different margins, it is often necessary to replace presser feet of different specifications, resulting in the need to prepare a variety of presser feet of different specifications, and the frequent replacement of presser feet is also troublesome. When sewing the ribbon and the base fabric, manual alignment is required and the relative position of the ribbon and the base fabric needs to be controlled during sewing. The control is difficult and it is easy to cause problems such as skewed and twisted ribbons. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a presser foot with adjustable sewing margin, which can directly adjust the margin on a sewing machine and has a ribbon sewing guide function.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a presser foot with adjustable sewing margin, including a pressure plate assembly, a movable edger and a fastener, one end of the pressure plate assembly is provided with a connecting part for connecting to a sewing machine, the middle part of the pressure plate assembly is provided with a sewing hole, the other end of the pressure plate assembly is provided with a positioning hole, the movable edger is provided with a margin adjustment hole and a edge baffle, and the fastener passes through the margin adjustment hole and is locked with the positioning hole.
[0006] Furthermore, an extension boss is provided at the other end of the pressure plate assembly, and the positioning hole is provided on the extension boss.
