Abstract

A knife sharpener comprises a knife fixing device, a grinding tool device, an angle adjusting device and a supporting device, the knife fixing device is used for fixing a knife to be ground, the grinding tool device comprises a driving mechanism and a grinding mechanism, and the driving mechanism is used for driving the grinding mechanism to rotate; the gravity of the driving mechanism can act on the cutting edge part of the to-be-ground knife through the grinding mechanism, so that the grinding surface of the grinding mechanism can be kept in contact with the cutting edge part of the to-be-ground knife at least in a working state; and under the driving of the driving mechanism, the grinding mechanism generates a grinding function on the cutting edge part of the to-be-ground knife through rotary friction motion, and the angle adjusting device is used for adjusting the included angle between the grinding surface and the to-be-ground knife. In the grinding process, even if the grinding surface of a grinding piece and the to-be-ground cutting edge part of the to-be-ground knife are abraded in the grinding process and / or the to-be-ground cutting edge surface of the to-be-ground knife is not smooth enough, the grinding surface and the to-be-ground surface of the to-be-ground knife can be always in close contact.

Description

technical field [0001] The invention belongs to the technical field of tool processing, and in particular relates to a knife sharpener. Background technique [0002] Knives, especially kitchen knives, are indispensable tools in the daily life of residents. Knives will passivate during use, which is commonly known as "not sharp". Therefore, the blades of knives need to be ground and repaired regularly to ensure their sharpness. Spend. Taking a kitchen knife as an example, the sharpeners in the prior art are generally divided into the following two types: [0003] A common knife sharpener includes two sharpening wheels. Each sharpening wheel has a sharpening surface and two sharpening surfaces are oppositely arranged, and a V-shaped groove is formed between the two sharpening wheels. When grinding the tool, place the blade of the tool to be ground in the V-shaped groove, and use the driving mechanism to drive the two grinding wheels to rotate to grind the blade. In this wa...
