Abstract

The utility model relates to a shear, in particular to a shear with a trajectory line shear edge. An upper shear blade and a lower shear blade which are matched with each other are interconnected together through a pin roll; and the upper shear blade and the lower shear blade are provided with a handle and a shear edge respectively. The shear is characterized in that the shear blades of the upper shear blade and the lower shear blade adopt the trajectory line shear edges and are in movable fit through the pin roll; and a shearing angle between the upper shear blade and the lower shear blade is between 21 and 26 degrees. The upper shear blade and the lower shear blade are formed by a shear element with the shear edge and the handle respectively through combined mould pressing. The shear has the advantages of novel concept, reasonable design, simple structure and convenient manufacture. In addition, the shear well solves practical problems met by people in the daily life.

Description

The scissors that trajectory line cutting edge is arranged

Technical field

The utility model relates to a kind of scissors, and the scissors of trajectory line cutting edge is particularly arranged.

Background technology

Existing scissors, it no matter is the scissors that the scissors used of tailor or paper-cut are used, it is with all using the staight scissors sword, be that people usually see the scissors that two one side that handgrip is arranged of mating mutually have the single face cutter of sword to make by the bearing pin commissure together, no matter its shape size is different, but mostly is the staight scissors sword.As Chinese patent literature 200510066425.3 disclosed " scissors ", its basic structure is: have two scissors elements and an armature assembly, two scissors elements are respectively equipped with a countersunk, run through this scissors element, and this armature assembly has a bolt and a nut.The daily cutter of certain some special use, as Chinese patent literature 200420095377.1 disclosed " a kind of multi-purpose cutter ", this novel multi-purpose cutter comprises that the tail end of handle of a knife, handle of a knife articulates multiple blade by bearing pin, the other end of handle of a knife is provided with rotating shaft and cutter anvil, connect an end rotationally by rotating shaft and be provided with the lever that arrives, the other end is provided with the scissor body of scissors cutting edge, and the cutter anvil outside is provided with blade, and described blade is an arc.The arc blade of two scissors cutting edges that cooperatively interact is one protruding one recessed.The different arcs of recesses blades of its effect separately are in order fixedly to be sheared thing, and the convex blade is for convenience of applying shearing force to being sheared thing.It is that special use is cut, and the scissors cutting edge is shorter for the handle of exerting oneself usually.It is heavy that scissor body seems, it is comparatively painstaking to use.Chinese patent literature 200320124462.1 disclosed " electric shear ", it is made up of supply unit, power set, transmission decelerating device, set of blades and housing.When connecting power supply, motor drives power transmission shaft by change-speed gearing, and power transmission shaft drives two staggered circular shear blades by deviator again and rotates simultaneously and realize cutting out.This device is applicable to industrial production cutting metal sheet material usefulness, and use need be taked safeguard procedures also, otherwise can cause security incident.Chinese patent literature 200520082808.5 disclosed " arc scissors " is a kind of medical tool, it comprises the handle that shear blade, lower scissors sheet, rotating shaft and shear blade up and down are connected separately, describedly goes up shear blade and the lower scissors sheet is 60-120 degree to the radian of the same side bending.It is in order to solve the situation that common scissors and scalpel use inconvenience and the broken ends of fractured bone is irregular, influence coincide healing.Reduce operator doctor work difficulty.Make and scope too narrow.

Summary of the invention

The purpose of this utility model is, improves row at the deficiencies in the prior art, proposes the scissors that also design has trajectory line cutting edge.

Technical solution of the present utility model is, adopt two last shear blades that mate mutually to be in the same place by the bearing pin commissure with the lower scissors sheet, last shear blade and lower scissors sheet all have handle separately, cutting edge separately, it is characterized in that, cutting edge on last shear blade and the lower scissors sheet adopts trajectory line cutting edge, both pass through bearing pin movingly, and the shearing inclination of Gou Chenging is between 21 °-26 ° between the two.

It is characterized in that last shear blade and lower scissors sheet form by scissors element that cutting edge is arranged and handle combination mold pressing.

Scissors is that two lever cross actions on the fulcrum are in an object.The shearing inclination of scissors is very important, and angle is big, and the power of shearing is smaller, but cuts incessantly, cut object and can slide into the less position of shearing inclination and just can cut to such an extent that live, but from fulcrum far away the shearing force increasing, when shearing harder objuct body such as sheet metal, the scissors easy deformation.Operation principle of the present utility model is, the characteristics of joining according to symmetric double trajectory line are littler than the two straight lines angle of joining when it is joined in opposite directions, changes and wants slow, so during this in use scissors that trajectory line cutting edge arranged of people, just can shear material at leisure.Shear blade and lower scissors sheet are when bearing pin rotates on the shearing material is in certain length, and the opening of cutting edge remains unchanged on certain angle, and often adjusts sheared edge when not required, the shearing work that so just is convenient for people to.

The scissors of two trajectory line cutting edges of the utility model design (the approximate parabola cutting edge of promptly two shapes of winding up) has good performance, and it does not change people's usefulness and cuts custom.In fact, if all various scissors (fulcrum shaft) as long as mix trajectory line cutting edge, just can obtain between the self-designed best shearing inclination (21 °～26 °).Concrete preparation method is: as long as move or relax or shortens the trajectory line arc that winds up, just can reach oneself needed shearing inclination.Conception of the present utility model has prolonged the cutting edge that effectively cuts of scissors, and during use, if be sheared the more close fulcrum shaft of thing, shearing will be lighter.Make any one shearing point can both obtain best shearing inclination, such scissors not only makes well also can be durable.Two trajectory line cutting edges that the utility model adopts make up this structure, can be displaced on the scissors of multiple structure, cut as short mouth Nail scissors, family expenses point mouth scissors, kitchen multi-purpose shears, Haircutting scissors, sewing scissors, tinsmith snips, medical operation etc.

The utility model has the advantages that, novel, reasonable in design, simple in structure, be convenient to make.Solved the practical problem that people run in daily life well.

The specific embodiment

Below, describe embodiment of the present utility model with reference to the accompanying drawings in detail.

As shown in Figure 1, the utility model adopts two last shear blades that mate mutually to be in the same place by bearing pin 2 with the lower scissors sheet, last shear blade and lower scissors sheet all have handle, cutting edge separately 3 separately, cutting edge 3 on last shear blade and the lower scissors sheet adopts trajectory line cutting edge, both pass through bearing pin 2 movingly, and the shearing inclination of Gou Chenging is between 21 °-26 ° between the two.Last shear blade and form by the 4 combination mold pressings of the scissors element that cutting edge 3 is arranged and handle.The lower scissors sheet is formed by scissors element that cutting edge 3 is arranged and handle 1 combination mold pressing.
