Description

Multifunctional knife sharpener

Technical field

The utility model relates to a kind of knife sharpener that is used for the various daily lifes of grinding with cutter.

Background technology

People need often to use multiple cutters such as kitchen knife, fruit knife and scissors in the daily life, these cutters its cutting edge rust after use a period of time, need grinding once more, the most original method for grinding is to adopt whetstone or frotton to carry out, this mode not only wastes time and energy, and household comparatively is particular about other be unwelcome.

The patent No. a kind of tool grinding device that has been " knife sharpener " patent disclosure of 97204304.7, be by the two emery wheel axles that are positioned on the same horizontal plane at least two emery wheels to be installed on the knife sharpener seat, knife sharpener can be on the emery wheel axle rotates with the knife sharpener seat relatively, and some is overlapped on the emery wheel axis direction for two emery wheels, offer the sharpening notch on the pairing knife sharpener seat of two emery wheel overlappings, during grinding knife tool, blade is put into from the sharpening notch between the periphery of two emery wheel overlappings and back and forth and twitched, can be fast that the cutting edge roundness grinding is sharp.

This kind knife sharpener can make things convenient for grinding to kitchen knife, fruit knife, but because its width (along the emery wheel axis direction) size is bigger, so can not carry out grinding to scissors easily, and when grinding knife tool, must hold the knife sharpener seat with palm, if use this kind knife sharpener to whet a knife, when the cutter accident when the sharpening notch skids off, the handwritten visiting card that is easy to hold the knife sharpener seat is hindered.

The utility model content

The purpose of this utility model provides a kind of multifunctional knife sharpener, can carry out grinding to the various cutters that use in the daily life that comprises scissors in safe ready ground.

Function knife sharpener described in the utility model comprises the knife sharpener seat and is installed in two pairs of emery wheels on the knife sharpener seat, offer the sharpening notch on the pairing knife sharpener seat of two emery wheel overlappings in the every pair of emery wheel, described knife sharpener seat is a strip, two pairs of emery wheels lay respectively at the two ends of knife sharpener seat, laterally offer the V-type notch at knife sharpener seat middle part along the knife sharpener seat, the both sides of V-type notch are fixed with abrasive disc, are set with the safety screen with knife sharpener seat matched in clearance on the knife sharpener seat.

One end of two emery wheels in the every pair of emery wheel is provided with chamfering, and this end is the abutting end of two emery wheels, and this end end face of two emery wheels is in the same plane.

The cross section of described knife sharpener seat is an isosceles triangle.

The knife sharpener seat is a strip, can make palm hold the knife sharpener seat easily knife sharpener is fixed; And the safety screen of suit on the knife sharpener seat can be separated the cutter of grinding with the hand of holding the knife sharpener seat, deviates from Shi Buhui in the cutter accident from the sharpening notch handwritten visiting card is hindered, and makes to have good safety guarantee when grinding knife tool.The abrasive disc that the V-type notch both sides of knife sharpener seat are fixing can carry out grinding to scissors and other daily life with cutter easily.

Because emery wheel is installed in knife sharpener seat inside, the thickness of emery wheel again can not be too small, so the installation of emery wheel need take the bigger horizontal space of knife sharpener seat, each of the utility model knife sharpener is in the same plane to the end face that two emery wheels in the emery wheel have chamfered end, thereby make two emery wheels go up no gap at its axis direction (being the horizontal of knife sharpener seat), can farthest reduce the lateral dimension of knife sharpener seat like this, so that the gripping of hand.And the setting of two emery wheel chamferings can make two emery wheels be separated by at the periphery infall of its overlapping necessarily to meet the space, crack, thereby the cutting edge of cutter can not damaged when grinding knife tool.

The cross section of knife sharpener seat is an isosceles triangle, can be convenient to hold the knife sharpener seat and feel good.

Knife sharpener described in the utility model can carry out grinding to the various cutters that use in the daily life that comprises scissors easily owing to have this kind structure, and safe and reliable when using.
