Abstract
The utility model discloses a kind of sewing-machine foot, including presser feet bottom plate, the hinged presser feet handle with the presser feet bottom plate, it is characterized by: the rear of the upper surface of the presser feet bottom plate, hole of threading a needle opens up cutter groove, oblique blade is placed in the cutter groove, pushing broach is compressed above the oblique blade, and setting conductor strip is compressed above the pushing broach.Compared with prior art, the utility model automatically can cut line with oblique knife after sewing finishing and the end of a thread is short, and structure is simple, can be transformed upgrading to existing sewing machine.
Description
Technical field
The utility model relates to sewing machine, specifically a kind of sewing-machine foot.
Background technique
Existing sewing-machine foot does not have automatic shearing function, but since sewing machine line number is more, artificial trimming efficiency
Low, the end of a thread is long, needs second pruning, low efficiency.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies that existing sewing machine is unable to automatic shearing, disclose a kind of energy automatic shearing
Sewing-machine foot, adopt the technical scheme that:
A kind of sewing-machine foot, including presser feet bottom plate, the hinged presser feet handle with the presser feet bottom plate, it is characterised in that: institute
State the upper surface of presser feet bottom plate, the rear in hole of threading a needle opens up cutter groove, the oblique blade of placement, the top of the oblique blade in the cutter groove
Pushing broach is compressed, setting conductor strip is compressed above the pushing broach.
Further, the oblique blade is the seperated oblique knife equal with the number of perforations of threading a needle, the sword of each seperated tiltedly knife
The direction of motion of mouth and line forms acute angle.
Further, it opens up equal with the number of perforations of threading a needle on the conductor strip and manifests thread a needle hole and the oblique knife
The oblong needle passing hole of piece cutting edge.
Further, the conductor strip extends to the outside of parabasal plate by folding ear and is fixed by pressing plate.
Compared with prior art, the utility model automatically can cut line with oblique knife after sewing finishing and the end of a thread is short,
Structure is simple, can be transformed upgrading to existing sewing machine.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment 1.
Fig. 2 is the explosive view of Fig. 1.
Fig. 3 is the partial enlarged view of Fig. 2.
Specific embodiment
Embodiment 1, referring to attached drawing, a kind of three line sewing machine presser feets, including presser feet bottom plate 1, it is hinged with the presser feet bottom plate 1
Presser feet handle 2,1 two sides of presser feet bottom plate pass through respectively torsional spring 3 be clamped parabasal plate 4, the upper surface of the presser feet bottom plate 1,3
The thread a needle rear in hole 12 opens up cutter groove 11, places oblique blade 5 in the cutter groove 11, the top of the oblique blade 5 compresses pushing broach
6, the top of the pushing broach 6 compresses conductor strip 7, and 3 are opened up on the conductor strip 7 can manifest thread a needle hole and the oblique blade
The slotted hole 71 of cutting edge, the conductor strip 7 extend to the outside of the parabasal plate 4 by folding ear 72 and are fixed by pressing plate 8.Institute
Stating oblique blade 5 is 3 oblique knives of fission, and each seperated tiltedly direction of motion of the cutting edge of knife and line forms 25 degree of angles.The pressing sole
Vertical sliding slot 13 is arranged in the two sides of plate 1, and the parabasal plate 4 has vertical guide rod 41, the guide rod 41 and the sliding slot 13
It is slidably matched.Card slot 14 is arranged in the two sides of the presser feet bottom plate 1, and through-hole 42, the torsional spring 3 is arranged in the upper end of the guide rod 41
One end be caught in the card slot 14, the other end penetrates in the through-hole 42.
