Description
本新型關於一種裁切工具,特別關於一種容易施力的曲線剪刀。The present invention relates to a cutting tool, in particular to a kind of curve scissors which are easy to apply force.
剪刀,主要為一種裁切工具,其主要包含互相樞接的兩刀體,以及分別連結於該兩刀體尾端的兩柄部,使用者操作該兩柄部,以控制該兩刀體相對開閉,而對物件進行裁切或修整。Scissors are mainly a cutting tool, which mainly includes two knife bodies pivotally connected to each other, and two handles respectively connected to the tail ends of the two knife bodies. The user operates the two handles to control the relative opening and closing of the two knife bodies to cut or trim objects.
然而,現有的剪刀在使用時,往往由於兩刀體的刃部皆呈直線延伸,因此,如果利用兩刀體的刀刃末端進行剪裁時,往往會因為相對兩刀體的刀刃之間的開口角度過小,而比較難施力。However, when the existing scissors are used, the blades of the two blades extend in a straight line. Therefore, when cutting with the ends of the blades of the two blades, it is often difficult to apply force because the opening angle between the blades of the two blades is too small.
為了改善利用現有的剪刀的刀刃末端進行剪裁,比較難以施力的問題,本新型的主要目的在於提供一種比較容易施力的曲線剪刀。In order to solve the problem that it is difficult to apply force when cutting with the blade end of the existing scissors, the main purpose of the present invention is to provide a curved scissors that is relatively easy to apply force.
為了達到上述的目的,本新型的曲線剪刀,其包含有互相樞接的一第一刀體及一第二刀體,其中: 該第一刀體具有一第一刀刃部,該第一刀刃部具有一第一刀緣、一第一平刀面,及一第一研磨面,該第一刀緣呈彎弧曲線,該第一平刀面朝向該第二刀體,該第一研磨面沿著該第一刀緣形成於該第一刀刃部,並且與該第一平刀面之間形成一第一刃角,該第一刃角的角度為15度至40度;以及 該第二刀體具有一第二刀刃部,該第二刀刃部具有一第二刀緣、一第二平刀面,及一第二研磨面,該第二刀緣呈彎弧曲線,該第二平刀面朝向該第一刀體,該第二研磨面沿著該第二刀緣形成於該第二刀刃部,並且與該第二平刀面之間形成一第二刃角,該第二刃角大於該第一刃角,該第二刃角的角度為45度至85度。 In order to achieve the above-mentioned purpose, the curved scissors of the present invention include a first cutter body and a second cutter body pivotally connected to each other, wherein: The first blade body has a first blade portion, the first blade portion has a first blade edge, a first flat blade surface, and a first grinding surface, the first blade edge is curved, the first flat blade surface faces the second blade body, the first grinding surface is formed on the first blade portion along the first blade edge, and forms a first edge angle with the first flat blade surface, and the angle of the first edge angle is 15° to 40°; The second blade body has a second blade portion, the second blade portion has a second blade edge, a second flat blade surface, and a second grinding surface, the second blade edge is curved, the second flat blade surface faces the first blade body, the second grinding surface is formed on the second blade portion along the second blade edge, and forms a second edge angle with the second flat blade surface, the second edge angle is greater than the first edge angle, and the angle of the second edge angle is 45° to 85°.
較佳的是,該第二刀體的第二刀刃部具有一第三研磨面,該第三研磨面與該第二研磨面鄰接,並且位於該第二研磨面遠離該第二平刀面的一側,該第三研磨面沿著該第二刀緣延伸,並且與該第二平刀面之間形成一研磨角,該研磨角的角度為10度至70度。Preferably, the second blade portion of the second cutter body has a third grinding surface, the third grinding surface is adjacent to the second grinding surface, and is located on a side of the second grinding surface away from the second flat blade surface, the third grinding surface extends along the second blade edge, and forms a grinding angle with the second flat blade surface, and the angle of the grinding angle is 10° to 70°.
較佳的是,該第二研磨面的厚度大於0.2公釐並且小於該第二刀刃部的厚度的2/3倍。Preferably, the thickness of the second grinding surface is greater than 0.2 mm and less than 2/3 times the thickness of the second blade portion.
較佳的是,該第一刀緣及該第二刀緣皆為單一曲率,且該第一刀緣及該第二刀緣具有相同的曲率半徑。Preferably, both the first knife edge and the second knife edge have a single curvature, and the first knife edge and the second knife edge have the same curvature radius.
較佳的是,該第一刃角的角度為23度至27度。Preferably, the angle of the first edge angle is 23 degrees to 27 degrees.
利用上述的技術特徵,本新型的曲線剪刀具有以下的功效增進:Utilize above-mentioned technical characteristic, the curve scissors of the present invention has the following effect enhancement:
1. 由於該第一刀刃部的第一刀緣及該第二刀刃部的第二刀緣皆為彎弧曲線,因此,即使利用該第一刀刃部及該第二刀刃部前端的位置進行剪裁時,該第一刀刃部及該第二刀刃部之間仍可以維持較大的開口角度,而方便使用者施力剪裁。1. Since the first blade edge of the first blade portion and the second blade edge of the second blade portion are curved curves, even when cutting with the positions of the front ends of the first blade portion and the second blade portion, a large opening angle can still be maintained between the first blade portion and the second blade portion, which is convenient for the user to apply force to cut.
2. 該第二刃角的角度較大,可以做為剪刀的靜止刀刃,在剪裁物件時支撐物件,該第一刃角的角度較小,較鋒利,可以做為剪刀的活動刀刃,提供較佳的切割力,因此,第一刀體及第二刀體相對閉合而裁切物件時,可提升剪裁的穩定度,而讓使用者更好施力,裁切厚度較薄的物件時,可覓免物件位移,並且更容易裁斷物件。2. The angle of the second blade angle is relatively large, which can be used as the stationary blade of the scissors to support the object when cutting the object. The angle of the first blade angle is small and sharp, and can be used as the movable blade of the scissors to provide better cutting force. Therefore, when the first blade body and the second blade body are relatively closed and the object is cut, the cutting stability can be improved, allowing the user to apply force better.
