5. SPECIFIC EMBODIMENT OF THE INVENTION

[0016] The invention is further described in detail below according to the attached figures.

[0017] During the specific implementation of the invention, embodiment 1 is as follows.

[0018] As shown in FIG. 1-3, a knife sharpener that can sharpen knives simultaneously on rough and fine grinding position of the knife sharpening seat comprises a knife sharpening seat (1), a cover plate (2), a knife sharpening groove (3) and a fine grinding column (5). The upper end of the knife sharpening seat (1) is provided with the cover plate (2). The lower end of the sharpening seat (1) is provided with a bottom fixing column (4). The inner bottom surface of the cover plate (2) is provided with two sets of connecting columns (8). A connecting groove (7) is arranged between the connecting column (8) and the knife sharpening seat (1). The center position of the knife sharpening seat (1) and the cover plate (2) is correspondingly provided with a knife sharpening groove (3) with notches (9) on both sides. The fine grinding column (5) is installed on the inner side of the sharpening groove (3) on the sharpening seat (1). A rough grinding plate (6) is set at a position symmetrical to the fine grinding column (5) based on the center of the cover plate (2).

[0019] Preferably, the fine grinding column (5) and the rough grinding plate (6) are inlaid on the cover plate (2). There are two fine grinding columns (5) and two the rough grinding plates (6) and the angle between them is 25-30. The angle between the fine grinding columns (5) and the rough grinding plates (6) is on the same horizontal line. The fine grinding column (5) is used for fine grinding the tool, and the rough grinding plate (6) is used for the rough grinding the tool. They are installed on the inner side of the same sharpening seat (1), which improves the convenience of use. The sharpening groove (3), the bottom fixing column (4) and the connecting groove (7) are integrally formed on the sharpening seat (1). The one-piece form ensures stability. In addition, the bottom fixing column (4) facilitates the connection of the external wooden base. The connecting column (8) is integrally formed on the cover plate (2). The connecting column is used for connection. The fine grinding column (5) is made of ceramic bars, and the rough grinding plate (6) is made of diamond or cemented carbide. Different materials can be used to achieve different sharpening effects.

[0020] Working principle: The device has two gears: the fine grinding position composed of the fine grinding column (5) and the rough grinding position composed of the rough grinding plate (6). The two gear grinding positions are kept on the same horizontal line. They can be used simultaneously, or can be used separately. The friction direction of the blade is kept at 45 from the horizontal direction. The knife can be pulled back from the tail of the blade. At the same time, two notches (9) are added to the sharpener, which can increase the integrity of sharpening blade of the tool and increase the applicability of the device. It is suitable for all kinds of knives to be sharpened. The function of the fine grinding position of the fine grinding column (5): finely sharpen the blade, repair the scratches on the blade, smooth the surface, and eliminate the small burrs on the blade. The function of the rough grinding position of the rough grinding plate (6): quickly shape the cutting edge, suitable for blunt knives. When in use, put the end of the knife into the sharpening edge to keep the blade perpendicular to the table and do not sway left and right. Press down with the usual sharpening force and then pull back from the tail of the blade.
