Description

The undaform fancy edge scissors

The utility model relates to a kind of daily life instrument class, is a kind of undaform fancy edge scissors.

At present, it is two plain films that the scissors that people generally use mostly adopt blade, can shear paper etc. smoothly when this scissors use, and its sheared edge is a straight line, but in that to shear cloth or special requirement certain attractive in appearance when waiting material, has many defectives during its shearing:

1, to shearing cloth, as silk flosssilk wadding, cotton cloth, chemical ﹠ blended fabric, light fleece etc., its sheared edge exist tear, plucking, cause waste of material, and influence the flatness of cloth, be unfavorable for making and process various article;

2, can not shear the material that needs special requirement, as when utilizing straight snips to shear lace, the user is difficult to grasp, its sheared edge is on average even, and lace is also unintelligible and regular;

3, can not shear its lace to cladding, increase its attractive in appearance and machining functions.

In addition, people have proposed the many technologies that can shear various laces according to above-mentioned situation and have cut, and sheared edge adopts the scissors of semicircle camber, two shear blades of these class scissors are inconsistent, in the processing and fabricating more complicated, in case it is not high to add mouthful precision, backguy easily in use, shearing is inhomogeneous to making.

The purpose of this utility model is to provide a kind of undaform fancy edge scissors with undaform edge of a knife at above-mentioned situation.

Fancy edge scissors of the present utility model includes two blades up and down that have handle respectively, and two blades are hinged by screw and nut, and the edge of a knife of two blades is the wave profile of tooth up and down, and the edge of a knife of two blades coincide mutually,

This fancy edge scissors can be sheared the undaform lace, can not tear and collude line in use, can be used for shearing cloth or some claddings.

Below in conjunction with accompanying drawing technology contents of the present utility model and architectural feature thereof are further described:

Fig. 1 is the structural representation of facing of the present utility model;

Fig. 2 is the left TV structure schematic diagram of Fig. 1;

Fig. 3 is the plan structure schematic diagram of Fig. 1;

Fig. 4 is the A-A sectional structure schematic diagram of Fig. 1;

Fig. 5 is the B-B sectional structure schematic diagram of Fig. 1.

Referring to Fig. 1, Fig. 2 and Fig. 3, undaform fancy edge scissors of the present utility model, include and comprise two blades 1 and 2 up and down that have handle 3 and 4 respectively, two blades 1 and 2 are hinged by screw 5 and nut 6, two blades 1 and 2 the edge of a knife are the wave profile of tooth up and down, and two blades 1 and 2 the edge of a knife coincide mutually, when two blades are closed gradually up and down, two blade profiles of tooth can be coincide smoothly, and the seaming phenomenon does not take place.

Referring to Fig. 4, the wave profile of tooth of two blades can be selected the different tooth pitch that cooperatively interacts as requested for use up and down, and its tooth pitch can be 2～40MM, maybe can select other size for use.

Referring to Fig. 5, last bottom knife is hinged by screw 5 and nut 6, so that two blades can open or closure smoothly by its hinged screw, about the structure of this respect and the structure basically identical of existing scissors, no longer elaborates at this.

Referring to Fig. 1, on the handle 3 of cutter, have card article 7 again, have with card article at the handle of a knife 4 of bottom knife and be furnished with block 8 mutually, in case when using, last bottom knife excess enthalpy misplaces.

Referring to Fig. 1 and Fig. 2, on the handle of cutter, be equipped with spring leaf 11 again, so that can open scissors flexibly when using by pin 9 and screw 10.
