Description

For the polymer scissors of paper-cut

Technical field

The utility model relates to a kind of scissors, especially relates to a kind of polymer scissors for paper-cut.

Background technology

Scissors is the twolip instrument of the sheets such as cutting cloth, paper, steel plate, rope, round steel or thread-shaped body, and two-edged interlocks, can folding.Traditional scissors main part is all metal material substantially, and conventional is irony.The handle portion of some scissors adopts plastic handle.

China Patent No. is that No. 200920291964.0 utility models disclose a kind of lace scissors, comprise scissors main body, and the blade of wavy edge is housed in the cutter groove of scissors main body.Which disclose the scissors for paper-cut.

China Patent No. is that No. 200620000747.8 utility models disclose a kind of tool scissors, comprise the left blade of cross-articulation and right blade, the epimere of left blade and right blade is with blade, hypomere is handle, hinge, with hinge axis hole, is installed in hinge axis hole in the junction of handle and blade, is connected with spring between handle, one of them handle upper end thereof of left blade and right blade has locking key, the keyway that the correspondence position of another blade adapts with the shape with locking key.Scissors can open by spring between handle automatically when in use, reduces labor intensity, and when not using, locking key can by blade locking at closure state.

The spring of traditional child's paper-cut scissors is arranged on handle part, and the weak point of existence is: 1, user's hand easily encounters spring, has potential safety hazard.2, spring exposes in the environment, gets rusty easily or drops, and the overall vision of scissors is not succinctly attractive in appearance simultaneously.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of reliable and secure polymer scissors for paper-cut.

The utility model solves the problems of the technologies described above adopted technical scheme: for the polymer scissors of paper-cut, comprise scissors main body, described scissors main body comprises two scissors single component, two scissors single component are coupling by pivot pin and are combined into chi structure, have between two scissors single component and be close to closed area centered by pivot pin, scissors main body is made of plastics, described being close in closed area is placed with torsion spring, torsion spring comprise annular ring and with from annular ring one two torsion bars of drawing, described annular ring is enclosed within the place that is coupling, two described torsion bars are embedded in the medial surface of corresponding scissors single component respectively.

Two described scissors single component comprise the first scissors single component and the second scissors single component, joint pin is provided with inside the first described scissors single component, second scissors single component is provided with through hole, and pivot pin is fixed on described joint pin through described through hole.By pivot pin, two scissors single component are combined into scissor construction.

Described annular ring is enclosed within outside described joint pin.

Two described torsion bars are respectively the first torsion bar and the second torsion bar, the madial wall of the first scissors single component is provided with the first groove holding described first torsion bar, the madial wall of the second described scissors single component is provided with the second groove holding described second torsion bar.Do not having under External Force Acting, the tension force of the first torsion bar and the second torsion bar makes scissors be in open configuration.When there being clamping to make every effort to overcome the torsion taking torsion spring, scissors can close up makes shear action.

The inner side of two described scissors single component is provided with the depressed area for placing annular ring.

The arranged outside of the second scissors single component has the block covering described pivot pin.

Scissors single component comprises body portion and handle portion, is provided with latch components between the handle portion of two scissors single component, and latch components comprises the locating dowel be arranged on rotating hook part on one of them handle portion and another handle portion.

Described torsion spring is that metal material is made.

Compared with prior art, what the utility model has the advantages that torsion spring puts into two scissors single component is close to closed area, and torsion spring is hidden in the inner side of scissors main body, eliminates the torsion spring security risk in use procedure, prevents torsion spring from hooking user or dropping.When torsion spring is in closed area, avoid because malaria gets rusty.Torsion spring is hidden in scissors main body, and the overall appearance of scissors is cleaner and tidier.Torsion spring is arranged on the place that is coupling, and the lever force of torsion bar is less, and it is applicable to the scissors of plastic material, because plastics scissors is lighter.This structure cannot be applied to metal scissors, and the weight of metal scissors is comparatively large, and spring can only be arranged between two handles.
