The knife sharpener comprises a shell formed by splicing a first half shell and a second half shell, the shell comprises a knife sharpening part and a handlepart, the first half shell and the second half shell are positioned and fixed through a positioning column structure, and the positioning column structure comprises a first positioning column, a second positioning column, a third positioning column and a fourth positioning column; the knife sharpener further comprises a first knife sharpening support arranged on the first positioning column and the fourth positioning column in a sleeving mode, a second knife sharpening support arranged on the second positioning column and the third positioning column in a sleeving mode, a first knife sharpening strip and a second knife sharpening strip, and the first knife sharpening support and the second knife sharpening support are distributed in a crossed mode to form an X-shaped included angle structure capable of clamping a knife edge; a first rail groove is formed in the upper end of the first knife sharpening support, a first spring cavity is formed in the lower end of the first knife sharpening support, and a first spring is arranged in the first spring cavity; and a second rail groove is formed in the upper end of the second knife sharpening support, a second spring cavity is formed in the lower end of the second knife sharpening support, and a second spring is arranged in the second spring cavity.

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. And the blade of cutter generally comprises three parts of knife back, blade body, blade, and the included angle of blade is different, and blade included angle is ...

AI Technical Summary

Problems solved by technology

And the blade of cutter generally comprises three parts of knife back, blade body, blade, and the included angle of blade is different, and blade included angle is often specifically set according to purpose etc., and the sharpening angle of the sharpening edge of existing knife sharpener Generally, it is a fixed sharpening angle, which does not have an adjustment function, and cannot adapt to different angles of blades. Often it is only hard to grind the angle of the blade into the sharpening angle of the sharpener, which cannot retain the angle of the blade itself. The effect of using the blade

In addition, the internal structure of the existing knife sharpener is relatively cumbersome and complicated, the processing and assembly processes are time-consuming, and the assembly efficiency is low, which makes it difficult to improve production efficiency and reduce production costs
