Knife sharpener that selects different sharpening angles or different sharpening forms by rotating sharpening component disc boyd with knob

Abstract

The utility model provides a knife sharpener that selects different sharpening angles or different sharpening forms by rotating a sharpening component disc body with a knob. The knife sharpener has a variety of grinding angles and sharpening components for sharpening different types of knives, which are concentrated and evenly distributed in one sharpening component disc body in the form of a disc. Through the axis rotation of gears on the knob and the gear transmission method, the disc body of the sharpener is driven to rotate to realize the function of selecting sharpening slots with different sharpening angles or different sharpening forms for sharpening.

         2 . The knife sharpener that selects different sharpening angles or different sharpening forms by rotating a sharpening component disc body with a knob according to  claim 1 , wherein a gear is fixedly designed on the knob assembly ( 16 ), and a gear is fixedly designed on the sharpening component disc body ( 17 ); the sharpening component disc body ( 17 ) is provided with a positioning post hole ( 23 ). 
     
     
         3 . The knife sharpener that selects different sharpening angles or different sharpening forms by rotating a sharpening component disc body with a knob according to  claim 1 , wherein the knob assembly ( 16 ), the sharpening component disc body ( 17 ) and the gear ( 10 ) are engaged with each other. 
     
     
         4 . The knife sharpener that selects different sharpening angles or different sharpening forms by rotating a sharpening component disc body with a knob according to  claim 1 , wherein the sharpening disc positioning bead positioning groove ( 24 ) is designed with a plurality of evenly distributed positioning slots around an axis, which are matched one-to-one with the sharpening disc positioning bead ( 19 ) mounted on the sharpening component disc body ( 17 ). 
     
     
         5 . The knife sharpener that selects different sharpening angles or different sharpening forms by rotating a sharpening component disc body with a knob according to  claim 1 , wherein the sharpening component disc body ( 17 ) is provided with a plurality of slots, and a range of the slots available is 3-10; the slot ( 25 ) provided on the sharpening component disc body ( 17 ) are correspondingly assembled with the sharpening component ( 7 ) with different angles; an angle of the sharpening component ( 7 ) may be designed such that a range of the angle on one side is 12°-30°, and a range of an included angle is 24°-60°; a sharpening material of the sharpening component ( 7 ) may be tungsten steel, ceramics or other various other sharpening materials. 
     
     
         6 . The knife sharpener that selects different sharpening angles or different sharpening forms by rotating a sharpening component disc body with a knob according to  claim 3 , wherein the knob assembly ( 16 ), the sharpening component disc body ( 17 ) and the gear ( 10 ) are engaged with each other so that under the rotation of a toggle wheel and the transmission of the gear ( 10 ), for the sharpening component disc body ( 17 ), the positioning bead ( 19 ) inside the sharpening component disc body ( 17 ) is matched with the slot on the sharpening disc positioning post ( 14 ) on the inner component support bracket right cover ( 11 ), thereby realizing the function of one-to-one pairing of the slots with different angles on the sharpening component disc body ( 17 ) and the notches on the main body upper cover ( 1 ).
