[0002] With the improvement of people's living standards, knife sharpeners have become an essential tool in daily life. Knife sharpeners have completely changed traditional sharpening methods, transforming single-sided sharpening into simultaneous double-sided sharpening, greatly increasing sharpening speed. Their unique sharpening angles also make knives exceptionally sharp. However, existing knife sharpeners generally only offer a single sharpening mode, such as coarse or fine sharpening, with relatively fixed functions. Some multi-functional sharpeners require manual replacement of sharpening components to achieve different sharpening functions, which is inconvenient and results in a poor user experience. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

A positioning ball is installed inside the right side of the outer casing. The switching wheel has several positioning slots corresponding to the positioning ball. The right end of the handle is hinged to the outer casing, and a push block is hinged to the middle of the handle. A spring plate is installed inside the handle, pressing against the lower end of the push block. A drive rod corresponding to the ratchet teeth is installed at the upper end of the push block. In use, pressing the handle upwards causes the drive rod on the push block to drive the ratchet to rotate clockwise. The positioning ball positions the switching wheel after rotation. The sharpening component aligns with the sharpening groove, allowing for sharpening. Different mounting slots accommodate different sharpening components, enabling coarse grinding, fine grinding, precision grinding, shearing, and single-sided grinding. Switching between different functions is achieved with a simple press, eliminating the need for manual replacement of parts. This expands the applicability of the sharpener.
