Description

The cutter that the knife back is whetted a knife

Technical field

This utility model relates to a kind of cutter, especially relate to a kind of can the cutter whetted a knife of the knife back.

Background technology

Cutter is the instrument that in daily life, every day is required for use, and the material of the chopping board owing to having is harder, cutter The number of times that sword directly contacts with chopping board is too much, or the food that hardness is bigger often cut by cutter, the most so makes Obtain the easy rust of blade of cutter；Now after cutter rust, in order to make blade recover sharp, it is common that will Cutter is ground on hone and instruments sharpenning bar；Owing to hone and instruments sharpenning bar need individually to buy and account for According to bigger space, being also inconvenient to carry, the most traditional hone or instruments sharpenning bar are in actually used process In have a lot of inconvenience.

Therefore, the most also there is the knife back of the cutter of minority to be provided with sharpening tooth, due to the narrower in width of the knife back, The sharpening tooth arranged on knife back surface, it is possible to the region of sharpening is the narrowest；Cause the scope whetted a knife little, whet a knife Weak effect, sharpening odontotripsis is fast, and cannot repair sharpening tooth；And other cutter is at this cutter When whetting a knife on the knife back of tool, this cutter hand-held is needed to carry out whetting a knife or need to be hung down by this cutter Whet a knife again after the most fixing, it has not been convenient to operation of whetting a knife, and be all can only to play instruments sharpenning bar to cutter now The effect that tool is simply polished, it is impossible to enough cutter is finely polished, and cutter is the most inconvenient Vertically being fixed, the most vertical fixed cutting tool is whetted a knife again, and the abrasion to this cutter blade is big.

Utility model content

For the problems referred to above of the prior art, the utility model proposes the cutter that a kind of knife back is whetted a knife, this Utility model solve sharpening weak effect on the knife back of present cutter in-convenience in use etc. technical problem.

The technical solution of the utility model is: the cutter that the knife back is whetted a knife, including cutter hub and handle of a knife, described handle of a knife With cutter hub is anterior or cutter hub rear portion is connected, described cutter hub is integrally formed with the knife back and blade；On the described knife back one Body is provided with bossy body, and the outer surface of described bossy body is provided with sharpening tooth, and described sharpening tooth is along the length of cutter hub Degree direction extends.

Further, described bossy body is circular in cross-section or polygonal list structure.

Further, the cross section of described bossy body is circular configuration, described bossy body and knife back edge intersection point The tangent line at place is a with the angle of cutter hub side, 90 ° < a < 180 °.

Compared with prior art, the beneficial effects of the utility model are:

1. this utility model is by arranging bossy body on the knife back, is provided with sharpening tooth on the outer surface of bossy body, So making the scope whetted a knife increase, this also makes sharpening odontotripsis slow, and therefore people can hold this cutter Other cutter is polished, is equivalent on instruments sharpenning bar, polish roughly other cutters；Can also will be somebody's turn to do Cutter is set level, then is polished by other cutters, is equivalent to other cutters are carried out careful polishing；So make Effect of must whetting a knife is more preferable, also makes to use more convenient to operate, also the blade of self cutter will not be caused mill Damage.

Detailed description of the invention

Below in conjunction with the accompanying drawings and the technical scheme in this utility model is further illustrated by embodiment.

Referring to the drawings 1,2, this utility model includes cutter hub 1 and handle of a knife 2, handle of a knife 2 anterior with cutter hub 1 or Cutter hub 1 rear portion connects, and cutter hub 1 is integrally formed with the knife back and blade 3；Bossy body 4 it is integrally formed with on the knife back, The outer surface of bossy body 4 is provided with sharpening tooth 5, and sharpening tooth 5 extends along the length direction of cutter hub 1；Protrude The setting of body 4 adds the area arranging sharpening tooth 5, thus increases the scope of sharpening, the most indirectly subtracts Delay the abrasion of sharpening tooth 5 so that cutting-tool's used life is longer.

Bossy body 4 is circular in cross-section or polygonal list structure, polygon can be pentagon, Hexagon, octagon and dodecagon etc., the surface area so making bossy body 4 is relatively big, arranges sharpening tooth 5 Area relatively big, the profile of kitchen knife is more attractive in appearance.

Referring to the drawings 3, the cross section of bossy body 4 is circular configuration, so makes the convenient manufacture of cutter, convex Go out and sharpening tooth 5 is conveniently set on body 4, the tangent line of bossy body 4 and knife back edge point of intersection and cutter hub 1 side Angle is a, Also ensure that and on bossy body 4, have enough areas that sharpening tooth 5 is set；When on the one hand so making cutter keep flat, Whet a knife more stable, will not shake during whetting a knife；When on the other hand making to whet a knife, it is to avoid other Cutter comes in contact with the sidewall of the cutter hub 1 of this cutter and collides so that the sidewall of this cutter hub 1 will not be damaged Wound.
