Sharpening blade and sharpener using sharpening blade

Abstract

The invention provides a sharpening blade and a sharpener with a detachable sharpening blade manufactured by the blade. The sharpening blade is characterized in that four seamed edges are equal in length, and bulges or sags for fixing are arranged at two ends of the sharpening blade. The sharpener comprises the sharpening blade, a sharpening blade fixing device and a sharpening knife holder, wherein a sharpening blade fixing groove is directly formed in the sharpening knife holder or is formed through a sharpening blade support. The sharpening blade is detachably arranged in the sharpening blade fixing groove. The sharpening blade support is axially connected to the sharpening knife holder; and two same sharpening blade assemblies are arranged on the sharpening knife holder in a way of being crossed in an approximate 'X' shape so as to form a 'V'-shaped sharpening knife port. Handrail parts and the sharpening blade assemblies on the sharpening knife holder are symmetric with regard toone same center shaft. The sharpening blade and the sharpener with the sharpening blade provided by the invention has the beneficial effects that the sharpening blade is easy to disassemble, assembleand replace; the four seamed edges can be used for sharpening a knife, so that the utilization rate of the sharpening blade is improved; and with the symmetric structure, knife sharpening can be carried out on two sides, and the sharpening blade assemblies are elastically connected, so that the knife sharpening angle can be changed, and a cutting edge is smooth.

Description

Technical field: [0001] The invention relates to the field of knife sharpeners, in particular to a knife sharpener and a knife sharpener using the knife sharpener. Background technique: [0002] At present, the knife sharpener that uses cemented carbide as the sharpening blade all uses the super hardness of cemented carbide to cut both sides of the blade with the edge of the grinding blade, thereby making the knife sharper. The structure of the double sharpening blade sharpener is roughly as follows: the two sharpening blades are placed crosswise one after the other, and fixed on the sharpening frame. When in use, hold the sharpener with one hand and hold the knife with the other. Press the blade of the knife against the bottom of the "V" shape formed by the two grinding blades and pull it. The edges of the left and right grinding blades can cut both sides of the blade like this. This type of knife sharpeners on the market now all fixes the sharpening blade on the knife s...
