CN202702269U - Scissors with handles running above cutting line - Google Patents

Abstract

The utility model relates to a pair of scissors with handles running above a cutting line, short for upper scissors. The back ends of scissor blades are vertically connected with one end of a curved arm, the other end of the curved arm is vertically connected with the front ends of the scissor blades, and the corner part formed by the vertical connection of the curved arm and the scissor handles is provided with a rivet which is movably connected with the two scissor blades. The pair of scissors has the beneficial effects that only one curved arm is added on the basis of the traditional scissors, so the structure is simple and the design is easy to realize; when the large hard objects, such as cartons, metal scales and the like, are cut, the operation is convenient, the hand clamping is avoided, the force can be normally applied in cutting, the cutting quality is ensured and the cutting efficiency is enhanced; the fine cutting is realized; and various functions of the traditional scissors are maintained.

Description

Handle operates in the scissors of shear line top

Technical field

The utility model belongs to a kind of worker and uses or Scissors.Be particularly related to the scissors that one handle operates in the shear line top.

Background technology

At present, the handle of known scissors generally is distributed in the both sides of knife edge part, when reducing object, owing to hold handle portion and move along the shear line direction, therefore, when the length of cutting object during greater than knife edge length, if continue to reduce in same direction, will be sheared thing and clamp hand.Such as, when shearing long paper shell, this phenomenon often occurs.Like this, not only cause easily staff injured, and, because people are forced to cutting, so that Cutting Edge is not straight.Therefore, affected the cutting quality.The special-purpose fabric dividing scissors that occurs at present, although handle tilts to the same side, curved boom is too short, tong still when cutting hardboard or iron plate.

The utility model content

The utility model purpose provides the scissors that a kind of handle operates in the shear line top, existing scissors easy tong and the not high defective of shearing quality when shearing long hardboard or sheet iron have been overcome, the utility model when shearing long hardboard or sheet iron handle in the same direction of shear line, like this, just avoid cutting tong and defective of low quality, and kept the various functions of conventional scissors.Compare with traditional scissors, can shear easily the hard surplus such as hardboard, iron sheet and also can carry out meticulous reduction.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of handle operates in the scissors of shear line top, it is characterized in that: the rear end of scissor blade vertically connects an end of curved boom, the other end of curved boom vertically connects the front end of scissors handle, and there is the rivet that is flexibly connected two shear blades curved boom and scissors handle corner connected vertically.

The beneficial effects of the utility model are,

This programme has only increased a curved boom to conventional scissors.Therefore, simple in structure, realize easily.When shearing long hard object such as hardboard, iron sheet, can avoid hand to be pressed from both sides, can normally exert oneself when making cutting, and guarantee to improve shear efficiency by shearing quality.And the various functions that kept conventional scissors.

Compare with traditional scissors, can shear easily the hard surplus such as hardboard, iron sheet and also can carry out meticulous reduction.

Description of drawings

Fig. 1 is the scissor construction schematic diagram that handle operates in the shear line top

Among the figure: 1. curved boom, 2. rivet, 3. rivet hole, 4. scissors handle, 5. scissor blade,

The specific embodiment

A kind of handle as shown in Figure 1 operates in the scissors of shear line top, the rear end of scissor blade vertically connects an end of curved boom, the other end of curved boom vertically connects the front end of scissors handle, and there is the rivet that is flexibly connected two shear blades curved boom and scissors handle corner connected vertically.

Handle operates in the scissors of shear line top, and the embodiment that is called for short ' cut the top ' is consistent with the embodiment of conventional scissors.Rivet is passed from the drift bolt hole of cutter and bottom knife, and cutter is upper, and then bottom knife, uses closing-up lower, can make.

Handle is above shear line when guaranteeing cutting, and the length of curved boom must be greater than the width of bottom knife handle.

This scissors is when shearing object, and handle operates in the top of shear line all the time.Namely in the scissors that assembles, on two blades with the part of the knife edge all from handle to same lateral bend, and arm akimbo span is from the height h1 with knife edge part lower limb, greater than the height h2 of handle perigee distance band knife edge part lower limb.

The knife edge of two blades part to same lateral bend, is connected the knife edge part of blade with long curved boom.Like this, just guaranteed that handle avoids hand to be pressed from both sides and guarantee shearing quality all the time in the outside of cutting object when shearing object.

Claims (1)

1. a handle operates in the scissors of shear line top, it is characterized in that: the rear end of scissor blade vertically connects an end of curved boom, the other end of curved boom vertically connects the front end of scissors handle, and there is the rivet that is flexibly connected two shear blades curved boom and scissors handle corner connected vertically.
