Description

Concave arc fruit knife

The arcs of recesses fruit knife that the utility model relates to belongs to domestic life cutting-tool engineering field.

In the prior art.The fruit knife cutting edge shape mostly is linear or convex, as shown in Figure 1.The blade of this shape is that line contacts with fruit surface, so during the cutting fruit skin, contact area is little, uses inconvenience.

The purpose of this utility model.Being to provide a kind of blade is the arcs of recesses fruit knife, increases the contact-making surface of blade and fruit surface, thereby improves the fruit knife cutting effect and save fruit knife manufacturing metal.

Arcs of recesses fruit knife, its key technology that the utility model provides are: the fruit knife blade is an arcs of recesses, and its corresponding hilt also can be thereupon to become arcs of recesses.

Arcs of recesses fruit knife of the present utility model, through evidence: because of the arcs of recesses blade cooperates with the fruit profile, thereby the area of cut is big when cutting fruit, cutting speed improves, and saving metal, reduce manufacturing cost, the hilt that it cooperates usefulness also can change arcs of recesses into, and is whole the light practicality of cutter, quick novel, not only can be used for fruit cutting, also can be used for the melon processing of vegetables, especially in the fruit cutting machines, if cutting blade is changed into arcs of recesses, its process velocity will be accelerated greatly, not only economical and practical but also high efficiency.

The embodiment of arcs of recesses fruit knife of the present utility model is shown in accompanying drawing 2,3, and the blade of fruit knife can be processed into arc shape with metal, and then puts the first edge on a knife or a pair of scissors.Its radian can be selected according to made chi overall length and width, and ratio is moderate to get final product, and the hilt of adapted also can get final product to place the suitable fit shapes of concave arc cutter, and it can save metal equally.

Claims (1)

1, a kind of arcs of recesses fruit knife it form by cutter and hilt, it is characterized in that: the blade of fruit knife is a concave arc shape.
