Abstract

The utility model relates to a pair of scissors with equal force, which belong to scissors. The pair of scissors with equal force is composed of two scissor blades, wherein, the lower part of a tip-shaped scissor head is provided with a scissor handle, and a scissor shaft hole is arranged between the scissor head and the scissor handle. The two scissor blades are fixed by a scissor shaft in the scissor shaft hole after folding, wherein, cutting edges of the scissors form an arc shape, and scissor blades on the periphery of the scissor shaft are provided with a plurality of through holes. The upper part of the scissor handle and the lower part of the scissor shaft are provided with uneven vice jaws. The arc-shaped cutting edges ensures that scissored objects are always at an optimal scissoring point, which saves labor for users to scissor objects. The utility model saves labor especially in scissoring iron sheets, and can be used as a pair of cutting pliers, so that the utility model has the advantage of multiple functions.

Description

Etc. the strength scissors

Strength scissors such as the utility model relates to a kind of scissors, and is particularly a kind of.

At present, the scissors that people use is made of two shear blades, and scissors has a pointed scissors bit, in the bottom of pointed scissors bit the scissors handle is arranged, scissors bit and scissors between cut axis hole, with two shear blades superimposed after, fix with scissors shaft in cutting axis hole, the edge of a knife of scissors is a linear.This scissors is in shear history, cut the object distance scissors shaft when near, it is the most laborsaving to be that the scissors mouth is sheared object when all opening, but be difficult to exert all one's strength, being cut object is easy to go to the place ahead of scissors mouth cunning from the rear of scissors mouth, this skidding mainly is owing to excessive the making of angle between two scissors mouths, when sliding into to a certain degree, certain a bit on the scissors cause for gossip execute shearing to object, this phenomenon is the most obvious when shearing iron sheet, this point of shearing object is best shearing point, and is at this moment the most laborsaving, and has only this point the most laborsaving; When surpassing this, cut the object distance scissors shaft when far away gradually, at this moment the angle between two scissors mouths is more and more littler, effort more during shearing.

The purpose of this utility model is that a kind of strength scissors such as labour-saving when shearing object using equal strength and shear object on whole scissors edges of a knife will be provided.

The purpose of this utility model is achieved in that the edge of a knife of scissors is a curved edge.

The radian of curved edge be two shear blades in shear history, be changed to 21 degree by 12 degree gradually from the angle of scissors shaft between pointed scissors bit place two shear blades.

Curved edge is to be an arc from the edge of a knife of scissors shaft between the pointed scissors bit, and the radian of this arc is that to keep angle between two edges of a knife in shear history be 21 to spend to two shear blades.

Shear blade in the scissors shaft periphery has a plurality of through holes; Irregular jaw on the position of the top of scissors handle, scissors shaft bottom.

Because having adopted such scheme, the edge of a knife of scissors is arc, when the scissors mouth opens entirely, the angle minimum between two edges of a knife; When the scissors mouth when closed, the shearing angle maximum between the two scissors mouths, thus use same strength when having guaranteed on whole edges of a knife of scissors, to shear object because the edge of a knife of scissors is a radian shape, when shearing object, it is non-slip at the edge of a knife to be cut object; To shear angle in whole shear histories between two edges of a knife be 21 when spending when adopting, the object that is sheared always is being on the sheared edge of whole scissors on the best shearing point (shearing angle), so it is the most laborsaving when shearing object, on scissors, there are a plurality of through holes to be used to cut off iron wire, on scissors, there is jaw can work as pliers and uses, reached the purpose of this utility model.This scissors is incited somebody to action the linear edge of a knife since the dawn of human civilization, invents to be curved edge, and the object that is sheared always is on the best shearing point, the most laborsaving when shearing object, best embody out its laborsaving performance when particularly using this scissor cut iron sheet, can also use one-object-many-purposes as combination pliers simultaneously.

Be described further in conjunction with the embodiments with reference to the accompanying drawings below.

Accompanying drawing is a structure chart of the present utility model.

Embodiment 1: scissors is made of two shear blades, scissors has a pointed scissors bit 4, scissors is arranged 3 in the bottom of pointed scissors bit 4, between pointed scissors bit 4 and scissors are 3, cut axis hole, with two shear blades superimposed after, fixing with scissors shaft 5 in cutting axis hole, shear blade in scissors shaft 5 peripheries has a plurality of through holes 2, at scissors 3 top, irregular jaw 6 on the position of scissors shaft 5 bottoms, the edge of a knife of scissors is a curved edge 1, the radian of curved edge 1 be two shear blades in shear history, be changed to 21 degree by 12 degree gradually from scissors shaft 5 to the angle between pointed scissors bit 4 places two shear blades, this scissors such as is at the strength scissors.

Embodiment 2: curved edge 1 is to be an arc from scissors shaft 5 to the edge of a knife between the pointed scissors bit 4, the radian of this arc be two shear blades to keep the angle between two edges of a knife in shear history be 21 degree, this scissors is the equal angles scissors.Other and embodiment 1 omit together.

Claims

1, strength scissors such as a kind of, be to constitute by two shear blades, scissors has a pointed scissors bit, in the bottom of pointed scissors bit the scissors handle is arranged, between scissors bit and scissors handle, cut axis hole, with two shear blades superimposed after, in cutting axis hole, fix with scissors shaft, it is characterized in that: the edge of a knife of scissors is a curved edge.

2, strength scissors such as according to claim 1 is characterized in that: the radian of curved edge be two shear blades in shear history, be changed to 21 degree by 12 degree gradually from scissors shaft to the angle between pointed scissors bit place two shear blades.
