Abstract

The utility model relates to a pair of scissors used by the left hand, which is formed by that two pieces of identical blades with handles and fasteners are connected. The utility model is characterized in that the shapes of the planar section and the convex section of the blades of the scissors are contrary to the shapes of the corresponding parts of the blades of the scissors in the prior art. When the left hand uses the scissors, the left hand can naturally flex fingers like the right hand to open or close the blades; two blades are staggered to produce shearing force to shear objects. The utility model has the advantages of labor saving and indefatigability and the utility model can exert the natural functions of the left hand.

Description

Scissors for left hand use

The utility model relates to a kind of scissors.

Usually people are accustomed to using scissors with the right hand, and existing scissors also is convenient to the right hand and is used.It is made up of two identical band handle blade and fixtures, and the staggered face of its blade is the plane, and another side is the convex surface that inclined-plane and plane constitute.During use, right thumb heel is pushed down the handle of scissors top, to lower left, the centre of the palm firmly, promotes blade and moves to the upper right side; All the other four fingers are held the handle of scissors below, and to upper right side, the centre of the palm firmly, the below is mobile left to promote blade, makes the blade two-edged staggered, and the two sides is close to, and produces shearing force, cuts off object.Yet, when left hand when the mode of counting on one's fingers is used scissors naturally according to the right hand, its result, the active force of generation separates the two sides blade, and two-edged is staggered, can not cut off object.For the blade two sides is adjacent to, two-edged is staggered, and left thumb must promote down the sheet blade and move to upper right side, the centre of the palm, and all the other four fingers promote last slice blade and move to lower left, the centre of the palm.This factitious force method of counting on one's fingers is relatively required great effort, and is tired easily, can not give full play to the advantage of left-handed person.

The purpose of this utility model is the version that will change existing scissor blade, and a kind of scissors that left hand uses of being convenient to is provided.

For achieving the above object, be that the one side on plane becomes convex surface with the blade of prior art scissors; The one side complanation of convex surface, promptly just in time the shape with the prior art scissor blade is opposite, and remainder is constant.During assembling, the planar portions phase-splitting of two identical band handle blades is pasted, fuse by fixture.

Characteristics: when left hand used the scissors of the utility model design, naturally count on one's fingers the same with the right hand just can make the blade two sides be adjacent to, and the staggered shearing force that produces of two-edged is cut off object.Laborsaving, indefatigability can be brought into play the natural functions of left hand.

The utility model is described in further detail below in conjunction with accompanying drawing.

Figure (1) is the front view that the utility model is convenient to the scissors of left hand use;

Figure (2) is the front view that the utility model is convenient to the scissor blade of left hand use;

Figure (3) is the rearview that the utility model is convenient to the scissor blade of left hand use;

Figure (4) is the front view of prior art scissors.

Referring to figure (1), the scissors that the utility model is convenient to the left hand use is that the planar portions phase-splitting of two identical band handle blades 1 is pasted, and is formed by connecting by the perforate in the middle part of two blades by the rivet 2 as fixture.

Described blade 1 is shown in figure (2), and its one side is the convex surface that inclined-plane and plane constitute, and the another side of this face is depicted as the plane as figure (3), and the middle part of blade 1 has hole 1-1, and handle 1-2 is arranged at the bottom.

The utility model is convenient to the scissors that left hand uses and is compared with the existing scissors shown in the figure (4), and difference is: blade 1 is the convex surface that has scissor blade 3 now for the one side on plane; The one side of convex surface is the plane of existing scissor blade.

Claims

1, a kind of scissors of being convenient to the left hand use, it is to be connected into by two identical band handle blade 1 and fixtures 2, it is characterized in that: the one side of described blade 1 is the plane, another side is the convex surface that inclined-plane and plane constitute, the shape of this plane and the convex surface just in time shape with existing scissor blade appropriate section is opposite, there is perforate 1-1 at the middle part of blade, and handle 1-2 is arranged at the bottom.
