Background technique

Cutter is also commonly called as icking tool or wallpaper knife, is a kind of fine arts and the knife for doing artifacts, is mainly used to cut matter The softer thing in ground, mostly modeling knife handle and blade two parts composition, are drawing and pulling type structure.Also having a small number of is knife handle of metal, blade Mostly angle can be fractureed along the scribing line of piece body with blunt, the new knife edge occurs, be easy to use, cutter has size Multiple Type.

Often seem unable to do what one wishes when cutting harder object, so needing the new edge of a knife and being able to solve these The scheme of problem.

Utility model content

The defect and deficiency of the utility model prior art of being solved provide a kind of flexible sawtooth cutter, increase spiral shell It is also easier than common cutter using the higher object of serrated knife blade cutting hardness while stud structure improves firmness degree It is laborsaving.

The utility model is achieved through the following technical solutions:

A kind of flexible sawtooth cutter, including blade, knife rail, knife handle, screw and sliding fixator；The blade cutting edge First half be saw, it is latter half of be blade, and it is described saw and blade in the same side；The zigzag fashion of the saw is that right-angle side is vertical In the right angled triangle of blade, and the right-angle side is towards the blade；The tail portion of the blade is provided with aperture；The sliding is fixed Device is provided with screw hole, and the blade is mounted on sliding fixator by screw, which includes push handle, fixing card, The fixing card is welded in push handle；The sliding fixator is mounted in knife rail, is provided on the knife rail and fixing card phase The card slot matched；The knife handle is mounted on knife rail.The usually used cutter of people mainly cuts more soft object, right Just seem that comparison is weak when paying coarse hard object, which uses jagged blade, more holds Coarse hard object is easily cut, and is connected using screw with screw hole in the design of connection type, more stable and stronger；And it is fixed Card is more reliable and more stable than general riveting using welding with push handle.

Further, the blade face is provided with several dents being parallel to each other, can be along recessed in cutter head rust Trace break it is disconnected, to obtain new cutter head.

Further, the knife handle surface is provided with several grooves, increases hand to the frictional force of knife handle, makes to take when holding more Add stabilization.

Further, the pad of the push handle and fixing card is solder joint.

Further, the mounting means of the knife handle and knife rail is to be bolted.

Further, the sliding fixator can slide in knife rail.

The utility model compared with prior art, has the following advantages and benefits:

1, a kind of flexible sawtooth cutter of the utility model is improved between blade, knife handle and knife rail using bolt and welding Solidness；

2, a kind of cutting that the serrated knife blade of flexible sawtooth cutter can be more convenient of the utility model；

3, a kind of flexible sawtooth cutter simple structure of the utility model, manufacturing cost is low, cost performance is high.
