Knife sharpener

Abstract

The invention discloses a knife sharpener. The knife sharpener comprises a vacuum sucker capable of being adsorbed on a plane and provided with a linkage rod, a linkage pin fixedly arranged on the linkage rod and capable of driving the linkage rod to longitudinally move, a base arranged outside the linkage rod in a sleeving manner and located above the vacuum sucker, a reset spring arranged outside the linkage rod in a sleeving manner and clamped between the base and the vacuum sucker to reset the vacuum sucker, a rotary seat arranged on the base, arranged outside the linkage rod in a sleevingmanner and capable of driving the linkage pin to longitudinally move, a rotary disc mounted above the base and linked with the rotary seat, a knife sharpening bottom plate located above the rotary disc and connected and fixed to the base, a knife sharpening structure fixedly arranged on the knife sharpening bottom plate, and a knife sharpening cover arranged on the knife sharpening bottom plate in a covering manner. The vacuum sucker comprises a sucker in a hollow cone shape, and the linkage rod arranged at the upper end of the sucker. The rotary seat rotates along with rotation of the rotarydisc, an arc-shaped bevel edge capable of driving the linkage pin to move is arranged at the upper end of the rotary seat, and an arc-shaped positioning groove clamped with the linkage pin is formedin the highest position of the arc-shaped bevel edge.

Description

technical field [0001] The invention relates to the technical field of knife sharpeners, in particular to a knife sharpener. Background technique [0002] Compared with traditional knife sharpeners, modern knife sharpeners have the advantages of fast sharpening speed, simple operation, convenient portability, and beautiful appearance. It is a scientific, practical, efficient and convenient sharpening tool, suitable for kitchen knives Outdoor knives, Damascus knives, ceramic knives and other knives are characterized by changing the traditional single-sided sharpening to double-sided sharpening, so that the method, angle, and efficiency of sharpening have undergone fundamental changes, and the sharpening efficiency has improved. Greatly improved, modern knife sharpeners are more and more widely used in daily life. The function of the existing knife sharpener is relatively simple, generally only has the function of sharpening the knife, the existing knife sharpener does not ha...

AI Technical Summary

Problems solved by technology

The function of the existing knife sharpener is relatively simple, generally only has the function of sharpening the knife, the existing knife sharpener does not have the functions of hanging plate, hook, suction cup, etc., and cannot meet the various needs of users, and the existing sharpener All knives need to take up storage space, which is inconvenient to store

In addition, the sharpening specifications of existing knife sharpeners are relatively single. Usually, a knife sharpener is only equipped with a sharpening structure of one specification, and can only perform grinding operations of a single mesh. When users need different sharpening requirements, , only different types of sharpeners can be purchased at the same time, which greatly increases the purchase cost of users. At the same time, too many sharpeners are not convenient for users to carry and use

In addition, the existing sharpening edge is generally provided with two sharpening bars, and the two sharpening bars are cross-displaced to form angled grooves. In this way, the number of parts is large, the assembly process is cumbersome and complicated, and the production efficiency is difficult to improve. Once one of the sharpening bars is displaced, it will affect the sharpening effect and affect the service life of the sharpener
