Abstract

The invention relates to a pair of auxiliary straight scissors. The auxiliary straight scissors comprise two scissor blades. Each scissor blade comprises a front end and a handle end. The scissor blades are symmetrically installed on a rotary shaft. Fastening rings are installed at the two ends of the rotary shaft. Calibrators are installed on the fastening rings in a sleeving mode. Each calibrator comprises two sets of clamping pieces, and the two sets of clamping pieces are connected through a telescopic rod. Each set of clamping piece comprises a supporting rod and a pressing rod, and the supporting rod and the pressing rod extend towards the front ends of the scissor blades in parallel. Idler wheels are installed on the side faces, opposite to the supporting rods, of the pressing rods, and the axes of the idler wheels are perpendicular to the scissor blades. All the idler wheels are made of elastic materials. Each calibrator further comprises a calibration plate. The calibration plates extent towards the handle ends of the scissor blades in the way of being parallel to the scissor blades. By the adoption of the scissors, accurate straight shearing can be achieved, the shearing efficiency is effectively improved, and meanwhile, the shearing precision is improved.

Description

Auxiliary straight line is cut

Technical field

The present invention relates to a kind of hardware & tools, particularly, be a kind of shears.

Background technology

Shears is one of common hardware & tools, and it can be used for cutting out cloth, paper and iron sheet；When using shears to be cut out, owing to material mostly is flexible, pliable material, therefore in tailoring process, cloth bending make the person of cutting out cannot the most linearly tailoring material, it is irregular that this makes material cut out, and causes raw-material waste；Additionally, material can hang downwards after cutting out, applying cross component force to the sheared edge of shears, also easily cause and cut out straight, this not only wastes material, also makes troubles for follow-up work.

Summary of the invention

For the problems referred to above, the present invention provides a kind of auxiliary straight line to cut, and this shears is capable of straight line more accurately and cuts out, and is effectively improved and cuts out efficiency, improves simultaneously and cuts out precision.

For solving the problems referred to above, the technical solution adopted in the present invention is: this auxiliary straight line is cut and included two shear blades, and shear blade includes front end and pommel；Described shear blade is symmetrically installed in rotating shaft, is provided with dead ring at the two ends of rotating shaft；

Sheathed on described dead ring aligner is installed；Described aligner includes two groups of holders, is connected by expansion link between two groups of holders；Often group holder includes the front end extension towards shear blade that pole and depression bar, pole and depression bar are parallel to each other；Being provided with roller on the side relative with pole of described depression bar, the axis of each roller is vertical with shear blade；Each described roller is made by elastomeric material；

Described aligner also includes calibration plate, the pommel extension towards shear blade that calibration plate is parallel with shear blade.

The invention has the beneficial effects as follows: material is placed between two separate two shear blades, material is positioned between depression bar and pole simultaneously；Pull open expansion link so that two parallel spacing out of holder；What material to be cut out was straightened is placed in shears, and reciprocal Guan Bi shear blade realizes cutting out of material；Control to cut out direction so that the edge of materials after cutting out is close to calibration plate and is slided, can ensure that material moves along the direction parallel with calibration plate；Material is by between depression bar and pole, and roller and material rolling friction, resistance is less, does not interferes with material and linearly moves.

Present configuration is simple, easy to operate, and the straight line that simultaneously can realize material is cut out so that cutting out of material is regular, standard, effectively reduces waste of raw materials, is that follow-up operation improves facility simultaneously.

As preferably, described pole is made by ferrimagnet, and depression bar is made by permanent-magnet materials；Under magneticaction, material is clamped by depression bar with pole, and then stability and accuracy are cut out in raising.

As preferably, offering anti-slip ring on described roller, described anti-slip ring is parallel with the plane at shear blade place；So that preventing material from breakking away, error is cut out in valiant fighter's reduction.

As preferably, offering the groove that string is parallel on calibration plate, each groove is parallel with depression bar；So that making the edge of materials after cutting out slide along groove, preventing material from hanging too early, shears mouth being applied side force, and then affects material and cut out.

Detailed description of the invention

Embodiment

In the embodiment shown in Fig. 1, Fig. 2, this auxiliary straight line is cut and is included two shear blades 1, and shear blade 1 includes front end and pommel；Described shear blade 1 is symmetrically installed in rotating shaft 11, is provided with dead ring 12 at the two ends of rotating shaft 11；

Sheathed on described dead ring 12 aligner 2 is installed；Described aligner 2 includes two groups of holders 3, is connected by expansion link 4 between two groups of holders 3；Often group holder 3 includes pole 31 and depression bar 32, and described pole 31 is made by ferrimagnet, and depression bar 32 is made by permanent-magnet materials；Pole 31 and depression bar 32 parallel to each other towards shear blade 1 front end extend；Being provided with roller 321 on the side relative with pole 31 of described depression bar 32, the axis of each roller 321 is vertical with shear blade 1；Offering anti-slip ring on described roller 321, described anti-slip ring is parallel with the plane at shear blade 1 place；Each described roller 321 is made by elastomeric material；

Described aligner 2 also includes calibration plate 5, the pommel extension towards shear blade 1 that calibration plate 5 is parallel with shear blade 1；Offering the parallel groove of string 51 on calibration plate 5, each groove 51 is parallel with depression bar 32.

Material is placed between two separate two shear blades 1, material is positioned between depression bar 32 and pole 31 simultaneously；Pull open expansion link 4 so that two parallel spacing out of holder 3；What material to be cut out was straightened is placed in shears, and reciprocal Guan Bi shear blade 1 realizes cutting out of material；Control to cut out direction so that the edge of materials after cutting out is close to calibration plate 5 and is slided, can ensure that material moves along the direction parallel with calibration plate 5；Material is by between depression bar 32 and pole 31, and roller 321 and material rolling friction, resistance is less, does not interferes with material and linearly moves.

The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
