Auxiliary straight line is cut
Technical field
The present invention relates to a kind of hardware & tools, is a kind of scissors particularly.
Background technology
Scissors is one of common hardware & tools, and it can be used for cutting out cloth, paper and iron sheet;Cut using scissors
During sanction, because material is mostly flexible, pliable material, therefore in tailoring process, cloth, which is bent, make it that the person of cutting out can not be accurate
Along straight line tailoring material, it is irregular that this causes material to cut out, and causes the waste of raw material;In addition, material can be downward after cutting out
Hang, the sheared edge to scissors applies cross component force, also easily causes and cuts out not straight, this not only waste of materials, also to be follow-up
Work make troubles.
The content of the invention
To be cut in view of the above-mentioned problems, the present invention provides a kind of auxiliary straight line, the scissors can realize that more accurately straight line is cut out,
Effectively improve and cut out efficiency, while improve and cut out precision.
To solve the above problems, the technical solution adopted in the present invention is:This auxiliary straight line, which is cut, includes two shear blades,
Shear blade includes front end and pommel;The shear blade is symmetrically installed in rotating shaft, and dead ring is provided with the both ends of rotating shaft;
It is arranged on the dead ring and calibrator is installed;The calibrator includes two groups of holders, two groups of holders
Between connected by expansion link;Every group of holder includes pole and depression bar, and pole and depression bar are parallel to each other towards shear blade
Front end extends;Roller is installed on the side relative with pole of the depression bar, the axis of each roller is vertical with shear blade;Respectively
The roller is made by elastomeric material;
The calibrator also includes calibration plate, and the calibration plate pommel towards shear blade parallel with shear blade extends.
The beneficial effects of the invention are as follows:Between material is placed in into two separated two shear blades, while material is placed
Between depression bar and pole;Pull open expansion link so that two holders are parallel to space out;What material to be cut out was straightened
It is placed in scissors, reciprocal closure shear blade realizes cutting out for material;Direction is cut out in control so that the edge of materials after cutting out is tight
Paste calibration plate to slide, you can ensure that material moves along the direction parallel with calibration plate;Material is by between depression bar and pole, roller
With material rolling friction, resistance is smaller, does not interfere with material along rectilinear movement.
The present invention is simple in construction, easy to operate, while can realize that the straight line of material is cut out so that material cuts out rule
Whole, standard, waste of raw materials is effectively reduced, while facility is improved for follow-up operation.
Preferably, the pole is made by ferrimagnet, depression bar is made by permanent-magnet materials;Under magneticaction,
Depression bar clamps material with pole, and then improves and cut out stability and the degree of accuracy.
Preferably, offering anti-slip ring on the roller, the anti-slip ring is parallel with the plane where shear blade;With
It is easy to prevent material from breakking away, valiant fighter, which reduces, cuts out error.
Preferably, offering the parallel groove of a row on calibration plate, each groove is parallel with depression bar;In order to make to cut out
Edge of materials afterwards is slided along groove, prevents material from hanging too early, applies side force to scissors mouth, and then is influenceed material and cut out.

Embodiment
Embodiment
In the embodiment shown in Fig. 1, Fig. 2, this auxiliary straight line, which is cut, includes two shear blades 1, before shear blade 1 includes
End and pommel;The shear blade 1 is symmetrically installed in rotating shaft 11, and dead ring 12 is provided with the both ends of rotating shaft 11;
It is arranged on the dead ring 12 and calibrator 2 is installed;The calibrator 2 includes two groups of holders 3, two groups of folders
Connected between gripping member 3 by expansion link 4;Every group of holder 3 includes pole 31 and depression bar 32, and the pole 31 is by ferromagnetism material
Material is made, and depression bar 32 is made by permanent-magnet materials;Pole 31 and the front end parallel to each other towards shear blade 1 of depression bar 32 extend;
Roller 321 is installed, the axis of each roller 321 is vertical with shear blade 1 on the side relative with pole 31 of the depression bar 32;
Anti-slip ring is offered on the roller 321, the anti-slip ring is parallel with the plane where shear blade 1;Each roller 321 is by bullet
Property material is made;
The calibrator 2 also includes calibration plate 5, and the pommel towards shear blade 1 parallel with shear blade 1 of calibration plate 5 extends;
The parallel groove 51 of a row is offered on calibration plate 5, each groove 51 is parallel with depression bar 32.
Between material is placed in into two separated two shear blades 1, at the same by material be positioned over depression bar 32 and pole 31 it
Between;Pull open expansion link 4 so that two holders 3 are parallel to space out;What material to be cut out was straightened is placed in scissors,
Reciprocal closure shear blade 1 realizes cutting out for material;Direction is cut out in control so that the edge of materials after cutting out is close to calibration plate 5
Slide, you can ensure that material moves along the direction parallel with calibration plate 5;Material is by between depression bar 32 and pole 31, roller 321
With material rolling friction, resistance is smaller, does not interfere with material along rectilinear movement.
The present invention is simple in construction, easy to operate, while can realize that the straight line of material is cut out so that material cuts out rule
Whole, standard, waste of raw materials is effectively reduced, while facility is improved for follow-up operation.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
