Description

Sewing-machine foot

The utility model relates to the accessory of Sewing machines, specifically is sewing-machine foot, and it is particularly suitable for multineedle sewing machine.

In the prior art, Sewing machines has the branch of single needle and spininess, and the spininess machine is custom-designed in order to satisfy some special sewing occasions to require.For example, two-needle sewing machine can be finished adjacent two-wire simultaneously and make, its presser feet is a whole plate body, the below correspondence that is every pin is offered a strip hole, this presser feet only is suitable for same block of cloth needs two-wire to make the occasion use, when two blocks of different clothes need adjacent making, wherein piece of cloth material should stay the cloth of certain width to collect mouth, its width is greater than the width between two sutures, this situation is present in the garment pocket place very at large, at this moment, presser foot of the prior art can't satisfy making of above-mentioned occasion.

The purpose of this utility model is to design the satisfied multi-thread stitching with the piece cloth of a kind of energy, can satisfy the cloth that is reserved with certain width again and collect the sewing-machine foot that the cloth of pig's tongue is made synchronously.

For achieving the above object, the technical solution adopted in the utility model is: a kind of sewing-machine foot, have two independently tool pillars at regular intervals at least, the pillar lower end is hinged with pressure foot, the level of pressure foot is provided with strip hole or gap to the plate face, the oblique perk of pressure foot front end, pillar upper end are connected with each other, and the member of connecting place links to each other with presser bar on the Sewing machines.

Because every group of pressure foot and pillar are independent of each other in the utility model, pillar is with suitable spatial separation is arranged, there is no special feature when making with the piece cloth, and when making the cloth that is reserved with volume pig's tongue, volume pig's tongue erects and passes from the space of an intercolumniation gradually, collect pig's tongue like this and be retained effectively, the cloth that contains volume pig's tongue is made again on corresponding cloth.
