Description

The durable cutter of special type

The utility model system at Chinese style cut the dish, meat cutting or cut bone and improved with the knife back of cutter and the shape of cutter root junction so that blade is more suitable for operator's gripping and the facility of transporting cutter.

Cut vegetables fruit, meat cutting food or cut bone with cutter (following general designation kitchen knife), different according to its blade and cutter root juncture generally are divided into the integrally formed person of steel plate; Or the cutter root is with two kinds of forging welding mode and blade bonders.The general used cutter of dining room cook is the latter, this kind kitchen knife, and its cutter root and knife back joint are almost the level and smooth shape (as shown in Figure 1) with knife back uniform thickness.Only represent: be used for cutting or cutting when cutting food in order to make kitchen knife according to the cook, preferable blade stability is arranged, removing needs by palm, thumb meat pad and middle finger, nameless, little finger of toe is to grip outside the handgrip, more need to buttress the knife back of cutter root and knife back joint with thumb and forefinger, in the use following disappearance must take place: because blade is thin, and cutter root and knife back joint are almost the level and smooth shape of uniform thickness, the knife back reaches and the joint of cutter root so must firmly pinch with thumb and forefinger, thus, easily make operator's thumb, forefinger and tiger muscular rigidity, and be unfavorable for long gripping; Moreover, since thumb, forefinger and tiger muscle firmly, cause transporting the wrist of cutter can not be neatly up and down or about transport cutter, benefit makes operator's arm tired and think that knife is heavy.

The problem that the utility model institute desire solves is: the shape of a kind of knife back of kitchen knife and cutter root joint is provided, makes the more demand of match operation person when operation of kitchen knife.

One of the utility model purpose is its structure of mat, cuts vegetables and fruits or meat product cutter making, easier support for thumb and forefinger, and after preventing long-time operation, thumb, forefinger and tiger muscle stiff.

Another its structure of purpose mat of the utility model, the gripping mode of this kitchen knife is identical with present, but thumb, forefinger only need gently hold up the cutter root projection below and the adjacent knife back to get final product, because thumb forefinger and tiger muscle do not need to exert oneself again, so can make the wrist of fortune cutter more flexible, be beneficial to long operation.

The another purpose of the utility model is its structure of mat, because the center of gravity of cutter is slightly shifted to the handgrip side, and is easy to the application of force, thus cut osteotome or other heavy cutter adopts this structure, but its blade thickness attenuate, and blade weight is being alleviated in 20%, still do not lose original effect.

According to the utility model, its principal character is: the knife back of blade and cutter root joint, this cutter root forms the projection that is suitable for pointing support in the both sides of the knife back, so that kitchen knife more meets the demand of ergonomics in the use.

According to the utility model, its another feature is: the cutter root of blade existing person widens, thickeies, and after the cutter root is engaged with knife back forging welding and being installed on handgrip, the center of gravity of this whole kitchen knife is slightly shifted to the handgrip side, so that kitchen knife is more agile in the use.

Fig. 1 engages the shape of back with the cutter root for the blade of existing kitchen knife;

Fig. 2 is the three-dimensional exploded view of the utility model;

Fig. 3 helps schematic diagram for the shape after the forging welding and thumb, forefinger.

1: the knife back 11: breach 2: cutter root 21: projection

" when utilizing thumb and forefinger, we tightly mediate the stalloy of 2～6m/m (2 to 6 millimeters), and up and down or when swinging, because the cause of exerting oneself, the muscle of thumb, forefinger and tiger is very easily stiff as can be known by the theory of ergonomics; And then causing the not nimble of wrist swinging, this is the puzzlement of general cook maximum when the fortune cutter.By being, the utility model is to cut vegetables and fruits and meat product cutter, its knife back 1 (sees also Fig. 2 with breach 11 increasings of cutter root 2 joints, for asking the diagram homogeneous, shape after blade system in the diagram has processed), simultaneously, this cutter root 2 is also widened, thickening, when making cutter root 2 and the knife back 1 forging welding be one, this cutter root 2 forms respectively in the both sides of the knife back 1 and is beneficial to the projection 21 (consulting Fig. 3) that finger is helped, again, for being suitable for thumb, the forefinger circle closes the back and helps the knife back 1 directly to see, the thickness after these cutter root 2 forging welding machine with 2t again 0～1m/m (2t adds 0～1 millimeter) be good (t is the thickness of the knife back); Moreover because of the thickening of cutter root 2, it is heavy that then the weight of cutter root 2 is not also comparatively commonly used person's summary, is installed in the handgrip so work as cutter root 2, can make the center of gravity of whole cutter slightly shift to the handgrip side, makes the hand of holding cutter more feel nimble.Gripping of the utility model or mode of operation: still be with palm, thumb meat pad and middle finger, nameless, little finger of toe grips kitchen knife handgrip (this part is identical with the person of commonly using), and thumb and forefinger circle close, and help when the knife back 1, the right position is in the lower edge of this cutter root projection 21, be that the thumb first knuckle is posted by on the knife back 1 and cutter root projection 21 of homonymy, and the opposite side of the knife back 1 and cutter root projection 21, then be respectively forefinger first knuckle and forefinger second knuckle recline (signal of consulting Fig. 3), thus, thumb and forefinger almost not too firmly can be held blade, again because of thumb, forefinger need not exerted oneself, then tiger muscle also can be not nervous, and then wrist is more flexible when the fortune cutter.

In sum, mat the utility model really can make cut vegetables and fruits or meat product with cutter grip and operation on more light, and before application, do not see openly, apply for a patent in accordance with the law the whence.
