Abstract
The invention discloses a sewing machine which comprises a machine body, a pair of presser feet, cutters and pins, wherein the presser feet are fixedly arranged at the bottom of the machine body; the cutters are slidably arranged at the bottom of the machine body and correspond to a plurality of leak holes which are arranged on connecting sheets connected with the middles of the presser feet; and the pins are arranged at the two sides of the cutters; one side of the machine body is also provided with two retractable expansion bars; the expansion bars are fixed by virtue of a first fixed bar and a second fixed bar, and slide synchronously; the first fixed bar is provided with a fixed part connected with the ends of the pins; and the second fixed bar is provided with positioning holes which can be used for positioning the pins. The sewing machine disclosed by the invention has the advantage that the positioning holes are arranged, thus the problem that because pins in the traditional sewing machine can be deflected, fabrics prepared through sewing have a deviation phenomenon can be solved.
Description
Technical field
The present invention relates to a kind of Sewing machines.
Background technology
Traditional dress makes that operator's qualification is very important in the process, faces machinist's famine, the raising of sewing device performance, and the dependence that garment production is broken away from operator's qualification is very important.Also be the problem always studied of sewing device expert for many years, tradition is made the dependence to operator's qualification, is mainly reflected in gimmick and the consummate degree of operator's material processed in the process of making, and this also is the key that improves sewing output.The contents such as the attachment to a sewing machine of the introduction of our large length of front, Special presser foot, operation model are important supplement to sewing device.Everything all is the standard sewing operation, make the result of study of operational standardization, sequencing, the appearance of automation, semi-automatic equipment is exactly the performance of these achievement in research mechanizations.But Sewing machines is owing to use for a long time, and pin can get loose because of some parts, and is fixing insecure, tends to like this cause the stitching of some fabrics to deflect.
Summary of the invention
For overcoming above-mentioned shortcoming, the object of the present invention is to provide a kind of can be so that the Sewing machines that sewing needle location does not deflect.
In order to reach above purpose, the technical solution used in the present invention is: a kind of Sewing machines, it comprises body, be fixedly installed on a pair of presser feet of the bottom of described body, slip be arranged at described body the bottom and with described presser feet in the middle of the pin that has the corresponding cutting knife of a plurality of small openings and be positioned at described cutting knife both sides on the brace that is connected with, one side of described body also is provided with two telescopic expansion links, described telescopic rod fixes and synchronous slide by the first fixed bar and the second fixed bar, and be provided with the fixed part that is connected with the end of described pin on described the first fixed bar, be provided with the locating hole that to locate described pin on described the second fixed bar, described telescopic rod is fixed in a side of described body by fixed cover, and described the second fixed bar two ends are fixedly connected by the end of connecting portion and described expansion link.
Preferably, also be provided with tension adjustment section on the described body, and described tension adjustment section comprises that the tension adjustment sheet that Gong the yarn that is oppositely arranged passes, the threaded connecting rod of tool, the screw thread that is arranged at described tension adjustment sheet one side are arranged at the nut of the end of described connecting rod, and be sheathed on the described connecting rod and be positioned at spring in the middle of described tension adjustment sheet and the nut.
Preferably, also be provided with a plurality of adjacent guide parts on the described body, be formed with the groove that can supply yarn to pass on the described guide part.
Owing to adopted technique scheme, be not difficult to find out that the setting of Sewing machines of the present invention by locating hole solves that pin in traditional Sewing machines can deflect and so that the problem of seam fabric generation deviation out.
