knife sharpener

Abstract

The invention relates to a knife sharpener. The knife sharpener is provided with a main supporting rod, wherein the two ends of the main supporting rod are respectively connected with height adjusting rods, the outer ends of the height adjusting rods are connected with wheels, the inner ends of the height adjusting rods are connected with the main supporting rod through height adjusting rod fixing screws, the middle section of the main supporting rod is connected with an auxiliary supporting rod, the rear end of the auxiliary supporting rod is connected with the main supporting rod, a knife fixing opening is formed in the front end of the auxiliary supporting rod and the knife fixing opening is connected with a knife fixing opening screw. Since the knife sharpener ingeniously realizes the fixed-angle fixation of a cutting edge which moves in parallel through indirect fixation between the wheels and the cutting edge, the knife sharpener has the advantages that the structure is simpler, the knife sharpener is convenient to use, the flat cutting edge at a proper angle can be more easily sharpened, longitudinal arc-shaped cutting edges which are needed by kitchen knives and the like can be easily sharpened and the like.
