Description
Technical field
The utility model relates to a kind of weaving presser feet, is specifically related to a kind of flatcar noose presser feet.
Background technology
At present, in fabrication processes, the phenomenon such as the flatcar noose under general presser feet exists rim of the mouth, limit inhomogeneous, crooked.For above-mentioned situation, manufactured a kind of presser feet with location structure, but because location structure is fixedly connected with presser feet, relatively limit in actual use, the scope of application is less, and presser feet is all fixedly connected with head of sewing machine, can not up-down adjustment, need often to change and use, so both reduced operating efficiency, also improved production cost.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, provide a kind of can free activity orientation, integral body can up-down adjustment, increase work efficiency, the Novel flatcar noose presser feet of realistic instructions for use.
Technical scheme: in order to solve the problems of the technologies described above, a kind of Novel flatcar noose presser feet described in the utility model, it comprises depression bar and briquetting, they are flexibly connected by alignment pin, between the depression bar at described alignment pin rear portion and briquetting, be provided with linking springs, at described briquetting front end, be provided with left tongue piece and right tongue piece, between described left tongue piece and right tongue piece, it is the needle tray that falls, in described briquetting bottom, be provided with location chimb, in described briquetting side, be provided with control button, described location chimb stretches by control button, on described depression bar top, be provided with presser feet tunable component, described presser feet tunable component comprises contiguous block, on described contiguous block, be provided with connecting hole, on described contiguous block, have degree of tightness groove, on the contiguous block at described degree of tightness groove place, be provided with fastener hole, on the other contiguous block face of described fastener hole, be provided with fixed bar.
Described location chimb is provided with two altogether, is separately positioned on briquetting two bottom sides.
Described left tongue piece is longer than right tongue piece.
Described briquetting is arc briquetting, and its front-end and back-end are all bent upwards.
Described location chimb is arranged on the length direction of described briquetting bottom.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model is controlled location the flexible of chimb by control button and positioned, location is reliable, easy to use, can meet various instructions for uses, adopt presser feet tunable component, can make the whole up-down adjustment of presser feet, the scope of application increases greatly, without changing presser feet, improved production efficiency, realistic instructions for use.
