Description

558478 V. Description of the invention (1) The present invention relates to a sharpener, more specifically, a driving group installed in the sharpener, and the driving group can be adjusted according to the thickness of the blade Designer of the angle between sharpening blades. Generally, the sharpeners (as shown in the first picture) seen on the market are mainly equipped with a set of sharpening blades (11) on the main frame (1), and V is provided on the sharpening blades (11). Shaped groove (1 2), and the inner wall surface (1 3) of the V-shaped groove (1 2) is made of a harder material than the tool; therefore, once the tool is used for a long time, its The knife edge will inevitably become passivated and cannot be used. At this time, the blade of the knife is placed in the V-shaped groove (1 2) of the sharpener, and the main body (1) is fixed at the same time, and then the knife is moved. The cutter is moved in the V-shaped groove (12) and caused to rub against the wall surface (13), thereby the blade of the cutter can be restored to a sharp state, so that the cutter can be used again; from the above-mentioned conventional sharpener Structure and use. The method shows that the sharpener seems to be enough to restore the sharpened edge of the passivated tool, but after in-depth discussion and research, it is not difficult to find that there are still defects. The drawback is that the general sharpener is only suitable for For thinner and thinner knives, such as utility knives and engraving knives, they are suitable for a sharpener, but cooking knives, fruit knives and kitchen knives are thicker than other knives. Each knife used in the family has a different blade thickness, so it is necessary to have multiple sets of sharpeners to use together, and the purchase of multiple different sets of sharpeners is relatively high in cost. Therefore, This defect, in the pursuit of ideals, practicality and progress, is an extremely urgent task to strive for improvement.

558478 V. Description of the invention (2) In view of this, the inventor of this case has carefully considered and accumulated many years of research experience in improving the sales of various sharpener structures and related products, and has developed an adjustable sharpener . The main object of the present invention is to provide an adjustable sharpener, which utilizes a driving group installed in the sharpener, and after the driving group is actuated, the included angle formed by the two grinding blades can be changed.
