Abstract

The utility model provides a fan -shaped kitchen knife, includes fan -shaped cutting edge, and fan -shaped cutting edge is fixed on the blade holder, is equipped with the arc guide rail that link up on the blade holder, and the handle of a knife inboard is fixed with the pivot, and the pivot is located in the arc guide rail. The arc guide rail is seted up along fan -shaped cutting edge direction, holds the handle of a knife, can come pushback to move the cutting edge and carry out the parallel lines cutting, and the effect direction of the power of cutting off is downwards perpendicular, labour saving and time saving.

Description

A kind of fan-shaped kitchen knife

Technical field

This utility model relates to a kind of hand cutting tool, particularly to a kind of fan-shaped kitchen knife.

Background technology

At present, the kitchen knife on market is sheet mostly, and shape has square or taper etc., it does not have movable part.

And cut the dish on chopping block, the route cut the dish is parallel segment in fact, cutting off from top to bottom with existing kitchen knife, effort and easily hinder hands, efficiency are not high yet, want efficiently to cut out the skilled cutter work that well-balanced dish slice dish sheet need to rely on we daily described cook to practise for a long time.

The kitchen knife of existing end strips handle of a knife, the active force cutting off downwards dish fails all to act on blade, and major part is all lost on handle of a knife, waste of manpower.

Summary of the invention

In order to solve, prior art kitchen knife structure is simple and crude, inefficient problem of cutting the dish, it is provided that a kind of fan-shaped kitchen knife, this kitchen knife is rational in infrastructure, efficiency of cutting the dish height.

For achieving the above object, this utility model is by the following technical solutions:

A kind of fan-shaped kitchen knife, including fan blades, fan blades is fixed on tool rest, and the arc-shaped guide rail that tool rest is provided with through is fixed with rotating shaft inside hilt, rotating shaft is located in arc-shaped guide rail.

Above-mentioned a kind of fan-shaped kitchen knife, the outer sheath of hilt rotating shaft is provided with cylinder.

Above-mentioned a kind of fan-shaped kitchen knife, the upper surface of hilt and tool rest has through hole, the transverse section of hilt through hole offers axis hole, the short axle at throw-out lever two ends is fixed in axis hole, back-moving spring it is provided with between throw-out lever and hilt, after the press-side of throw-out lever is pressed, the thrust end of throw-out lever is by the rotating axis locking inside hilt.

Above-mentioned a kind of fan-shaped kitchen knife, hilt and offer through arc on tool rest and hold hole, when throw-out lever blocks the rotating shaft inside hilt, the hole of holding of hilt overlaps with the hole of holding of tool rest.

Arc-shaped guide rail is offered along fan blades direction, holds hilt, and blade can be promoted back and forth to carry out parallel lines cutting；And cut off the action direction of power vertically downward, time saving and energy saving.

Cylinder is set, in order to reduce the frictional force of rotating shaft and arc-shaped guide rail outside hilt rotating shaft.

The installation of throw-out lever, can make blade and hilt not produce relative motion, make whole cutter keep stationary state, it is simple to chop and cut.

Arc through on hilt and tool rest holds offering of hole, when pressing for throw-out lever borrow power: thumb pressing throw-out lever time, all the other four refer to through holding hole；So that press pressure larger.

Figure is labeled as: 1 blade, 2 tool rests, 3 hilts, 4 throw-out levers, 41 perforates holding cylinder outside hole, the short axle of 42 throw-out levers, the thrust end of 43 throw-out levers, 5 rotating shafts, 6 rotating shafts, 7 arc-shaped guide rails, the perforate of 8 tool rest upper surfaces, 9 hilt upper surfaces.

Detailed description of the invention

With reference to accompanying drawing, a kind of fan-shaped kitchen knife, including fan blades 1, fan blades is fixed on tool rest 2, the arc-shaped guide rail 7 that tool rest is provided with through, and is fixed with rotating shaft 5 inside hilt, and rotating shaft is located in arc-shaped guide rail, and the outer sheath of hilt rotating shaft is provided with cylinder 6；The upper surface of hilt and tool rest has through hole 8,9, the transverse section of hilt through hole offers axis hole, the short axle 42 at throw-out lever two ends is fixed in axis hole, back-moving spring it is provided with between throw-out lever and hilt, after the press-side of throw-out lever is pressed, the thrust end 43 of throw-out lever is by the rotating axis locking inside hilt；Offering through arc on hilt and tool rest and hold hole, when throw-out lever blocks the rotating shaft inside hilt, the hole of holding of hilt overlaps with the hole of holding of tool rest.

Holding hilt, promote hilt back and forth, rotating shaft fixing on hilt promotes blade to cut food materials along parallel lines track in arc-shaped guide rail.

When needs are cut and are chopped, throw-out lever on thumb pressure hilt, all the other four fingers insert the through hole of holding of hilt, tool rest, and throw-out lever rotates downwards along short axle, rotating shaft on hilt is stuck in the end of arc-shaped guide rail by the thrust end of throw-out lever, keeps blade, tool rest and hilt to be relatively fixed.Unclamping the throw-out lever of pressing, throw-out lever can be returned to horizontal level by back-moving spring so that the rotating shaft inside hilt can continue to slide in arc-shaped guide rail.
