Description

A kind of sewing-machine foot

Technical field

The utility model relates to sewing machine, specifically a kind of sewing-machine foot.

Background technique

Sewing-machine foot is an essential components in the feeding mechanism of sewing machine, various various forms of sewing Machine presser feet plays very important effect in process of production, such as seizing open-wire line, implicit type zipper sewing machine special presser feet, is pleated Sewing-machine foot etc. selects different sewing-machine foots extremely important in different sewing operations.

The applicant discloses a kind of anti-Bird's Nest device of flat seam machine previously with publication number CN105544098A, and specifically discloses Shallow slot is set at the middle part of presser feet bottom plate, dise knife is inlayed in shallow slot, setting can hold suture between two presser feets of presser feet bottom plate The gap penetrated, the circumferential blade covering part gap of dise knife.But there is also the spaces of improvement for this structure: holding what suture penetrated Gap is located at the side stitched with presser feet bottom plate bipod toe needle, so that the end of a thread entrance is not smooth enough, in addition for cutting line in dise knife The place that head actually works occupies dise knife seldom a part but occupies presser feet bottom plate larger area, and processing technology is caused to waste, In addition, the blade front for being transmitted through the suture and dise knife come from gap is mutually met, the movement of broken string is " cutting ", compared to needed for " cutting " Strength it is larger and dise knife is worn very fast.

Summary of the invention

The purpose of this utility model is the sewing-machine foot that open one kind is capable of overcome the deficiencies in the prior art, is taken Technical solution is:

A kind of sewing-machine foot, including presser feet bottom plate, the presser feet handle hinged with presser feet bottom plate, the presser feet bottom plate include a left side Toe and right toe, between the left toe and right toe be arranged needle stitch, it is characterised in that: on the presser feet bottom plate, the needle seam extension Setting holds suture and passes through, stitches the crossed beam trunking for communicating and seamlessly transitting with the needle on line, is arranged in the middle part of the presser feet bottom plate shallow Slot, the shallow slot is interior to place semicircular ring blade, is placed with hold(ing)-down clip on the semicircular ring blade.

Further, round rectangle shallow slot, the bottom setting of the round rectangle shallow slot are set in the middle part of the presser feet bottom plate The shallow slot, the shallow slot are semi-circular shape, and the string of the shallow slot is overlapped with a long side of the round rectangle shallow slot, described The hold(ing)-down clip is placed in round rectangle shallow slot

Further, it meets to setting metallic channel at the angle of the presser feet handle of the crossed beam trunking.

Compared with prior art, the utility model improves place where troops were originally stationed Bird's Nest presser feet, by blade tangent position by original Middle position be changed to be placed on side, change to be cut to and cut, former crossed beam trunking is changed to center by original side, it is ensured that secant It is smooth, stable, edge wear is reduced, secant the end of a thread is shorter.
