Multifunctional efficient protective tool

Abstract

The present invention is a new-type kitchen cutting tool suitable to be used in households, canteens, restaurants etc. It is an entirely-new multi-edge protective tool consisting of several blade units and the supporting tool holder for holding the blade unit, used for cutting the food material into slices, shreds and dices. The blade unit and the tool holder may be securely connected through the fitting between the “convex” and “reverse concave” slide rails as well as the “nut-type” or the “bolt-type” structure, and the blade unit may be changed so that the food material may be cut into slices, shreds and dices with different sizes and thicknesses. The tool edge, the thin thread functioning as the tool edge and the chopping board may be protected through the combination of the protective plate and the elastic blade or the thin thread, greatly extending their service life. The present invention is featured as easy operation, convenient, safe, high efficiency, raw material-, energy- and time-saved, wide application range and good quality of processed products.

1 . The new-type tool is composed of tool handles ( 1 ), took holder ( 2 ) and blade units ( 3 ), with the tool handles ( 1 ) and they took holder ( 2 ) installed on the blade unit ( 3 ). 
     
     
         2 . The features of the new-type tool mentioned in  claim 1  include: the mentioned blade unit ( 3 ) is composed of the mentioned peripheral protective plate ( 7 ) and several blades or thin threads, and it works through the combination of the protective plate ( 7 ), the elastic tool edge and the thin thread ( 4 ); each of the mentioned blades or thin threads has a certain elastic deformation capability when desired, and the range of such elastic deformation is just required to ensure the protective plate ( 7 ), the elastic blade and the thin thread ( 4 ) can play the protection role; the mentioned thin thread which is used to work instead of the tool edge is made of special material. Besides, the width of the tool edge or the circumscribed circle diameter of the cross section of the thin thread is less than 3 mm; there are some small holes ( 10 ) in each of the mentioned blades, and the obtuse face of the tool back is more than 1 mm lower than the protective plate ( 7 ); the upper part of the mentioned protective plate ( 7 ) is “convex”, outside which, there is a “nut” ( 6 ) that may be inserted, and the height of the protective plate ( 7 ) is within 3 cm; the food material may be cut into slices, shreds or dices quickly only through 1 to 3 times of cutting; the sharp face may be in the same plane with the lower part of the protective plate, or the sharp face is up to 5 mm longer than the lower part of the protective plate, or up to 5 mm shorter than the lower part of the protective plate. The sharp face may be made into different two-dimensional or three-dimensional shapes. 
     
     
         3 . The features of the new-type tool mentioned in  claim 1  include: the side face of the lower part of the mentioned tool holder is ±-shaped (“±” is a Chinese character) or t-shaped)), the upper transverse short line of the ±-shaped structure stands for the reverse concave-shape sliding chute ( 8 ), the lower transverse short line in such structure stands for the “bolt” ( 9 ) used for inserting, and the vertical short line in the same structure stands for the tool holder. 
     
     
         4 . The features of the new-type tool mentioned in  claim 1  include: if only one tool edge is used, then the present invention will be a new-type kitchen cutting tool with a very small blade.
