Abstract

The utility model relates to an arc whetstone, the whetstone is whole to be convex, and the face of whetting a knife that it was used for whetting a knife is the circular arc sector, and this circular arc sector occupies a fourth ring, and along the tangential direction of circular arc sector, its both ends are whetting a knife and hold the whole story. The adoption arc has increased the friction surface the when whetstone uses as the whole shape of whetstone for whetstone difficult appearance when using is slided, the face of whetting a knife of circular arc sector is and along tangential direction as whetting a knife the direction for cutter superiors more is easier.

Description

A kind of arc hone

Technical field

This utility model relates to hone, especially a kind of arc hone.

Background technology

Hone is conventional household goods, it mostly is strip, there is multiple problem in use in this hone, first be the hone of strip in use, easily mobile, so supporting underframe is fixed, secondly it is subject to width restriction in sharpening superiors's process and repeatedly to whet a knife and just can complete the complete superiors of blade, and cause between the senior middle school of two ends low in the process of continuing on, cause relatively larger waste.

Utility model content

The utility model proposes a kind of arc hone, make sharpening superiors be more prone to, not easily moveable during sharpening.

To achieve these goals, this utility model adopts the following technical scheme that a kind of arc hone, and hone is circular arc generally, its sharpening face being used for whetting a knife is circular arc covering of the fan, this circular arc covering of the fan occupies 1/4th annulus, and along the tangential direction of circular arc covering of the fan, its two ends are end at the whole story of whetting a knife.The global shape of hone is improved to circular arc, and sharpening face is also correspondingly improved as circular arc covering of the fan, and is as the criterion with quadrant ring, because along the tangential direction of circular arc covering of the fan, the most easily whet a knife superiors in the sharpening face of quadrant ring.Relatively long bar shaped hone, circular arc hone friction area increases, and not easily slides.

As preferably, the width of described circular arc covering of the fan is 40 millimeters to 50 millimeters.The width of 40 millimeters to 50 millimeters is enough for domestic knife.

As preferably, hone thickness is 20 millimeters to 30 millimeters.From angle hone thickness durable and easy to use.

As preferably, the inner arc radius of hone is 140 millimeters, and width is 45 millimeters.

As preferably, the bottom surface of hone is fixing connects skid resistant course.Skid resistant course is set further, it is ensured that hone does not slide in use.

Compared to existing technology, advantage of the present utility model essentially consists in: adopts arc as the global shape of hone, increases rubbing surface when hone uses, further preferably arrange skid resistant course in bottom surface so that hone does not have slip in use；The sharpening face of circular arc covering of the fan and along tangential direction as sharpening direction so that cutter superiors more be more prone to.

Fig. 2 is the left view of Fig. 1.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is further described.

Referring to Fig. 1 and Fig. 2, a kind of arc hone, hone is circular arc generally, its sharpening face 1 being used for whetting a knife is circular arc covering of the fan, this circular arc covering of the fan occupies 1/4th annulus, and when whetting a knife, cutter is whetted a knife along the tangential direction of this circular arc covering of the fan, so along the tangential direction of circular arc covering of the fan, its two ends are end at the whole story of whetting a knife.Preferred as the present embodiment, the width of described circular arc covering of the fan is 40 millimeters to 50 millimeters, namely the difference of circular arc covering of the fan inner circle radius and exradius is 40 millimeters to 50 millimeters, wherein inner circle radius can be 120 millimeters to 160 millimeters, the circular arc covering of the fan often flexibility that inner circle radius is too big is less, be not suitable for this utility model, and the width of circular arc covering of the fan be 40 millimeters to 50 millimeters enough for domestic knife sharpening superiors.

One as the present embodiment is preferred, and the inner arc radius of hone is 140 millimeters, and width is 45 millimeters.Hone under this preferred size, it is easy to deposit, once whetting a knife substantially along sharpening face for existing domestic knife can complete superiors.

Preferred as the present embodiment again, hone thickness is 20 millimeters to 30 millimeters.Hone it is also contemplated that durable process and moves conveniently, and 20 millimeters is proper to 30 millimeters.

The global shape of hone is improved to circular arc, sharpening face is also correspondingly improved as circular arc covering of the fan, and it is as the criterion with quadrant ring, because the tangential direction along circular arc covering of the fan, the sharpening face length and width of quadrant ring is all the superiors that the most easily whets a knife, relatively long bar shaped hone, circular arc hone friction area increases, not easily slide, in order to be further ensured that hone does not slide in use, the bottom surface of hone is fixing connects skid resistant course 2, and this skid resistant course can select rubber to be pasted on hone ground.

Except above preferred embodiment, this utility model also has other embodiment, those skilled in the art can be variously modified according to this utility model, without departing from spirit of the present utility model, all should belong to the scope that this utility model claims are defined.
