The axis of the first lever body and the axis of the second lever body are eccentrically arranged, all kinds of fabrics with different thicknesses can be met through more than two plane grooves formed in the second lever body, generality is enhanced, the convenience of the operation is improved, and the take-up lever eccentric pin is suitable for all kinds of lockstitch sewing machines.
Description
Technical field:
The utility model belongs to Sewing machines accessory technical field, refers in particular to a kind of thread take-up tension lever cam pin.
Background technology:
The effect of thread take-up tension lever assembly is in each work period of stitching forming process, controls the thread take-up tension lever supply and reclaims an amount of upper thread, and the stitching that upper thread and bottom line are formed tightens up, and extracts the needed line amount of using of stitching out from spool.It is the stroke of regulating thread take-up tension lever by the offset of change thread take-up crank in the prior art.When making the fabric of different-thickness, the stroke of thread take-up tension lever is also different, just needs to regulate to realize by changing thread take-up crank, and it is very inconvenient to operate.
Summary of the invention:
The purpose of this utility model provides a kind of highly versatile, applicable to the thread take-up tension lever cam pin of different-thickness fabric.
The utility model is achieved in that
A kind of thread take-up tension lever cam pin includes the body of rod one and the body of rod two, and an end of the body of rod one is connected with an end of the body of rod two, and the eccentric axis setting of the axis of the body of rod one and the body of rod two is provided with the plane of orientation groove that two above intervals arrange at the outer surface of the body of rod two.
Above-mentioned plural plane of orientation groove arranges along the face of cylinder spiral of the body of rod two.
The other end of the above-mentioned body of rod one is provided with the convex edge.
The advantage that the utility model is given prominence to compared to existing technology is:
The body of rod one of the present utility model is set for the eccentric with the axis of the body of rod two, can satisfy by the plural planar slot that arranges on the body of rod two fabric of various different-thickness, has strengthened versatility, has improved the simplicity of operation, is applicable on the various flat seam machine.
Description of drawings:
Fig. 1 is one of schematic diagram of the present utility model;
Fig. 2 is two of schematic diagram of the present utility model.
The specific embodiment:
The below is further described the utility model with specific embodiment, referring to Fig. 1-2:
A kind of line-choosing connecting rod cam pin, include the body of rod 1 and the body of rod 2 20, one end of the body of rod 1 is connected with an end of the body of rod 2 20, and the eccentric axis setting of the axis of the body of rod 1 and the body of rod 2 20 is provided with the planar slot 30 that two above intervals arrange at the outer surface of the body of rod 2 20.
Above-mentioned plural planar slot 30 arranges along the face of cylinder spiral of the body of rod 2 20.Angle between the setting of planar slot 30 and the planar slot 30 can be regulated and make the required thread take up lever stroke of various fabrics.Form anchor point at planar slot 30.During use, on the sewing machine case corresponding to the plane between air line distance be provided with one to one adjustment screw, when selecting different thread take up lever stroke, realize at corresponding planar slot 30 by screw-driving.
The other end of the above-mentioned body of rod 1 is provided with convex edge 40.Convex edge 40 and the body of rod one 10 axis conllinear.
Above-described embodiment only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
