Abstract

The utility model discloses a multi-purpose lace and buttonhole stitching apparatus, comprising a forked lever (1), a ratchet pawl (2), a casing (3), a ratchet wheel (4), and a balance wheel (5). The utility model is characterized in that the multi-purpose lace and buttonhole stitching apparatus is designed with a machine frame (6) having the supporting function. The multi-purpose lace and buttonhole stitching apparatus overcomes the shortcoming that the functions of an existing hole locking apparatus and an existing buttonhole stitching apparatus is single. The multi-purpose lace and buttonhole stitching apparatus can used for making lace as well as sewing buttonholes; also, the structure is simple, the cost is low, and the service is long; so the utility model is an ideal appliance for countrysides, towns, unions, individuals, and familiies.

Description

Multi-purpose lace and buttonhole stitching apparatus

The utility model is to belong to process the utensil that lace, buttonhole are used on a kind of Sewing machines.

The various locking devices of using on the existing Sewing machines can only be made lockhole usefulness, and the edge of lockhole is energy line not, and grenadine occurs easily that phenomenon, mass effects such as hook line, bouncing pilotage are not good in actual applications; And button holing machine equally also can only be made lockhole usefulness, and costs an arm and a leg, and investment greatly can only be fit to large-scale producer, is not suitable for family's sewing.

The purpose of this utility model be for overcome above-mentioned shortcoming provide a kind of can be used for lace, again can buttonhole use many with lace buttonhole devices.

Technical solution of the present utility model is that frame, pendulum plate, adjustable plate, jaw lever, ratchet pawl, ratchet, escapement etc. are processed into structure as shown in the figure, is assembled into many with lace buttonhole device.Earlier presser feet on the Sewing machines is taken off during use, load onto this lace buttonhole device, drive the jaw lever by the shank dog on the Sewing machines and move up and down, realize rotating by ratchet pawl, ratchet and escapement.

Owing to adopted the technical program, compared with the prior art the utility model has tangible advantage, can lace, can be used for buttonhole again, and simple in structure, cheap, easy to use, the life-span is long, is present rural area, market town, association, individuality and home-use desirable utensil.

Embodiment:

Below in conjunction with accompanying drawing the utility model is described in detail.What proposed is many with lace buttonhole device, it comprises jaw lever (1), ratchet pawl (2), case (3), ratchet (4), escapement (5), and design has the frame (6) that play supporting role, be equipped with escapement (5) in the centre of frame (6), be equipped with jaw lever (1), ratchet (4) on one side, on jaw lever (1), be equipped with the ratchet pawl (2) that matches with ratchet (4); To be equipped with pendulum plate (7) in the bottom of frame (6), to control width in order regulating in the use, the tail end top of frame (6) is equipped with adjustable plate (8).The said pendulum plate in front (7), in order to make this utensil can lace, again can buttonhole, its pendulum plate (7) is provided with two kinds, first kind is that lace is used, as Fig. 5, shown in Figure 6, the front portion offers control cloth breach (9) and lead piece (10), and the middle part is equipped with roller (11), so that link to each other with escapement (5), when escapement (5) rotated, roller drove pendulum plate (7) and swings in the curved groove of escapement (5), and the rear portion is " V " shape prong; Using for buttonhole for second kind, as Fig. 7, shown in Figure 8, is to have the rule hole on the rule sheet (12) of front end perk with first kind of institute's difference.

The course of work, earlier presser feet on the Sewing machines is taken off during use, load onto this lace buttonhole device, driving jaw lever (1) by the shank tailor's cushion head on the Sewing machines moves up and down, ratchet (4) stirred by ratchet pawl on the jaw lever (2) and escapement (5) rotates simultaneously, therefore roller (11) drives in the curved groove of escapement (5) and puts plate (7) and swing, and reaches the requirement of various font needle trackings required on the cloth; During as buttonhole,, promptly change the pendulum plate (as Fig. 7, pendulum plate shown in Figure 8) of buttonhole,, can reach the purpose of buttonhole with last same principle as long as change pendulum plate (7).
