Description
Technical field
This utility model is related to a kind of accessaries of sewing machine, and in particular to a kind of use in sewing machine moving knife.
Background technology
With the development of industrialization sewing machine, hammer-shears is cut sewing machine thread and is gradually replaced by automatic tangent apparatus, existing
Sewing machine moving knife blade in cutting thick line on the market, exist and be difficult cutting line, the easy bifurcated in tangent line end cross section, injustice,
The problems such as frequently changing moving knife is needed when tangent line is frequent.
The content of the invention
Not enough for existing structure, this utility model patent provides a kind of use in sewing machine moving knife small volume, and simple structure is made
Valency is low, and the technical scheme taken is：
A kind of use in sewing machine moving knife, including fixed part and tangent line portion, it is characterised in that the bottom in the fixed part and tangent line portion
Face is arc surface, and the tangent line portion includes cutting edge and crossed beam trunking, and the cutting edge inclines an angle A, the cutting edge relative to Z axis
An angle B is inclined relative to Y-axis, the fixed part is provided with screw hole.
Further, the fixed part and the arc surface in tangent line portion are decentraction circular arc.
Further, the cutting edge inclines an angle A relative to Z axis, and the angle is between 10 and 20 degree.
Further, the cutting edge inclines an angle B relative to Y-axis, and the angle is between 3 and 8 degree.
Further, the quantity of the screw hole is two.
Compared with prior art, advantage of the present utility model：Moving knife is changed to plane cutting edge by traditional convex cutting edge, is lifted
Cutting edge sharpness, improves trimming effect, extends the service life of product；The fixed part of moving knife is with the arc surface in tangent line portion for not
Isocentric circular arc, improves the trimming effect of product；Moving knife cutting edge inclines an angle relative to Z axis, Y-axis, improves trimming effect
Rate；Moving knife after special thermal treatment, possesses good wearability and sharpness, it is ensured that tangent line is totally neat, service life
It is long.
A kind of use in sewing machine moving knife of this utility model is described further with reference to specific accompanying drawing.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the front view of Fig. 1.
Specific embodiment
As illustrated, a kind of use in sewing machine moving knife, including fixed part 1 and tangent line portion 2, it is characterised in that the fixed part 1
It is arc surface with the bottom surface in tangent line portion 2, the tangent line portion 2 includes cutting edge 3 and crossed beam trunking 4, and the cutting edge 3 is inclined relative to Z axis
One angle A, the cutting edge 3 inclines an angle B relative to Y-axis, and the fixed part is provided with screw hole 5.
Fixed part 1 is decentraction circular arc with the arc surface in tangent line portion 2.
Cutting edge 3 inclines an angle A relative to Z axis, and the angle is 13.5 degree.
Cutting edge 3 inclines an angle B relative to Y-axis, and the angle is 5 degree.
The quantity of screw hole 5 is two.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of without departing from design spirit of the present invention, technical side of the those of ordinary skill in the art to the present invention
Various modifications and improvement that case is made, all should fall in the protection domain of claims of the present invention determination.
