Description

Technical Field

[0001] The utility model relates to a sewing machine accessory, in particular to an adjustable gauge. Background Art

[0002] In the process of sewing clothes, in order to make the openings such as collars, sleeves, and trouser legs look beautiful, it is generally necessary to sew a sideline at a certain distance from the opening. The function of the gauge is to make the sideline go in a straight line, which has the function of precise positioning. Most of the existing gauges are fixed gauges, such as the Chinese utility model patent with application number CN201720848882.6 and the name of Sewing Machine Presser Foot Gauge and Sewing Machine. This gauge has a single function. When used, it can only sew straight sidelines with fixed margins. It also has certain requirements for the thickness of the fabric. Fabric that is too thick cannot be stuffed into the gauge's pressure plate, and fabric that is too thin cannot have the function of flattening the fabric. The fabric is prone to wrinkling during the sewing process, resulting in a relatively low sewing efficiency of the sewing machine, which brings great inconvenience to the user. Utility Model Content
