What the present invention relates to is a kind ofly not only to can be used for cutting out paper, cloth, pruning plant and hair and can be used to cut off multi-purpose shears cutter wiry.
When using traditional scissors, by the thinner or harder material cut often owing to the rotation of a shear blade described scissors that is pushed out or slips away.In addition, resemble usually between two shear blades, folding of paper or hair and so on than thin or flexible material.
In the manner described above, when the chucking power of shear blade is not enough, the centrifugal force that the shear blade that is rotated produces will be cut material and be released scissors.
That is to say that when scissors was cut an object B according to shear blade E1 of usefulness shown in Figure 10 and another shear blade E2, the point of contact e on the shear blade E2 rotated around scissors crossing point O, thereby cause the cosine α of radius oe to increase.In other words, when cutting object B, the thrust that applies along shear line makes object B move towards the direction that deviates from crosspoint o.
In order to improve the chucking power of shear blade, crosspoint and scissors handle all will have sizable bias with the extended line of shear blade, and be perhaps that shear blade is inwardly curved so that prune plant.Yet, because the shear blade of this scissors departs from direction of operating, thereby operation inconvenience.
In addition, when when hair-cutting, because the slip on the scissors of very thin hair, thereby to be trimmed to equal length and need repeatedly repeat to shear.
In addition, the sliding surface of scissors is arranged on contiguous fulcrum place.Thereby, behind this surface wear, must sharpen scissors with quite high technology.And, because sliding surface is quite big, thereby usually needs to change scissors behind this surface wear, thereby reduced the service efficiency of scissors.
The objective of the invention is to,, any object of a kind of clamping tightly, its how hard, thin or soft haircut scissors no matter are provided, thereby can prune exactly by overcoming above-mentioned defective.
In addition, the present invention also provides a kind of nimble barber's shears of operation that has, to eliminate around the wearing and tearing of fulcrum and to prevent the scissors that very thin hair slips away.
Barber's shears of the present invention keeps in repair easy and does not have rattle.
For achieving the above object, scissors of the present invention comprises one first shear blade, lower limb at this blade has a shear blade, be respectively arranged with a first handle part and a second handle part in the bottom of shear blade, a pivot is supporting shear blade rotationally, the axis of this pivot is arranged on the top of the blade of second shear blade, and the support that is used to insert described pivot is arranged on the upper limb of first and second shear blades.
According to this configuration, first shear blade will be sheared object and inwardly draw when rotating, thereby will make shear blade bite this object securely, so that shear.
As shown in figure 11, when shearing object B with a shear blade E1 and another shear blade E2, the shearing point e of shear blade E rotates around scissors crossing point O.So the cosine α of radius oe shortens.Promptly, there is a power that object is pulled to above-mentioned some O along the edge of shear blade E1.
There is one to be separately positioned on first and second support sections shear blade edge part, evagination and a sliding surface on the barber's shears of the present invention around pivot.Because this sliding surface is detachable, thereby the maintenance of scissors is very easy.
In addition, sliding surface can be made with lubricious material, so that shear smoothly.
