Abstract

The utility model discloses scissors. Two blades of the scissors are hinged with an estimate rod through a pin, one side of the pin is provided with a limit column, an extension projection at the lower end of the estimate rod is matched with the limit column, the estimate rod can only rotate towards one side, and the top end of the estimate rod and the endpoints of the two blades are positioned on a concentric circle. Cutting positions can be accurately estimated, efficiency is improved, and materials are saved.

Description

A kind of scissors

Technical field

The utility model relates to a kind of hand cutting tool, is specifically related to a kind of scissors.

Background technology

Scissors is the common tool of people's cutting object.When the scissors of prior art opened cutting object, people were generally through feeling to estimate the clipped position that when two blades are closed, can arrive.When estimating when far away, cause the excessive irreversible result of cutting than reality.Cause the waste of material like this, reduce the efficient of work.

Comprehensively above-mentioned, present scissors also has further improved space.

The utility model content

The utility model technical problem to be solved is that the deficiency that is directed against prior art provides a kind of scissors that can estimate clipped position.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of scissors, comprise first blade, first handle of a knife, and second blade, second handle of a knife and bearing pin, bearing pin is hinged with two blades, and said bearing pin also is hinged with one and estimates bar.

The top of the said top of estimating bar and two blades is on a concentric circles.

Bearing pin one side has a limited post.

There is a protuberance the said rear end of estimating bar, and bearing pin one side is provided with and can keeps off the limited post of joining with said protuberance, and bar is estimated in restriction can only be to a sideway swivel.

Prior art is compared, and the advantage of the utility model is: can estimate clipped position accurately.Raise the efficiency, save material.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Shown in Figure 1 for a kind of scissors that can estimate clipped position, comprise first blade 1, first handle of a knife 7, the second blades, 2, the second handle of a knifes 4 and the bearing pin 6, bearing pin 6 is hinged with two blades.The top of the said top of estimating bar 5 and two blades is on a concentric circles.Bearing pin 6 one sides have a limited post 3.There is a protuberance the said rear end of estimating bar 5, and bearing pin 6 one sides are provided with and can keep off the limited post 3 of joining with said protuberance 8, and bar 5 is estimated in restriction can only be to a sideway swivel.

When using the present embodiment scissor cut, bar 5 is estimated in rotation earlier, when the extension protuberance of estimating rod rear end 8 and limited post 3 retaining timings, estimates bar 5 and is positioned in the middle of two blades, and estimate bar 5 and be in positioning states this moment.To estimate the object that bar 5 touch required cutting afterwards, it is corresponding with the target clipped position to estimate the masthead end simultaneously, and completion is estimated.Both hands are held handle and are sheared required cutting object, two blade cuts target piece, when two blade tops when estimating the masthead end and coincide, accomplish shear action.

Claims (4)

1. scissors; Comprise first blade (1), first handle of a knife (7), second blade (2), second handle of a knife (4) and bearing pin (6); Bearing pin (6) is hinged with two blades, it is characterized in that: also be hinged with one on the said bearing pin (6) and estimate bar (5).

2. scissors according to claim 1 is characterized in that: the top of the said top of estimating bar and two blades is on a concentric circles.

3. scissors according to claim 1 and 2 is characterized in that: said bearing pin (6) one sides be provided with one with the said adaptive limited post (3) in rear end of estimating bar.

4. scissors according to claim 3 is characterized in that: the said rear end of estimating bar (5) is provided with a protuberance (8), and this protuberance and described limited post retaining is joined, thus restriction estimate bar (5) can only be to a sideway swivel.
