Description

knife sharpener

The invention relates to a sharpening device, in particular to a sharpener capable of adjusting the distance between sharpenings.

The tool is a common cutting tool in daily life. After a certain tool is used for a period of time, the blade will be worn or passivated due to frequent cutting. Therefore, in order to restore the sharpness of the blade, the sharpening stone is usually used. Grinding tools such as sharpeners are used to grind the blade to restore the sharpness.

The traditional block whetstone needs to operate the blade surface in a hand-held manner to reciprocate on the surface of the sharpening stone to achieve the function of the grinding blade. Therefore, the user must control the angle and force of the sharpening blade, and the grinding angle of the blade surface is very good. Difficult to obtain smooth control, and a little careless, easy to cut the hand, but also has the disadvantage of not easy to collect.

There is a knife sharpener, which mainly installs a set of grinding blades on a body, and the set of grinding blades is formed with a V-shaped groove, so that the cutting edge of the cutter can be directly placed in the V-shaped groove of the sharpener, and The blade and the sharpener are moved relative to each other and rubbed against the grinding blade. With this type of sharpener, the volume of the grinding blade can be reduced, and the angle of the sharpening blade can be controlled without using the blade, and the blade can be restored more easily. To the sharp state; however, this type of sharpener still has the following disadvantages: 1. This sharpener is only suitable for cutters whose blade thickness is similar to that of the V-shaped groove; 2. The grinding blade will also be produced after use. Wear, causing the gap of the V-shaped groove of the grinding blade to become large and affecting the effect of sharpening.

In view of the above, the main object of the present invention is to provide a sharpener capable of adjusting the gap size of a sharpening groove, comprising: a base comprising a sharpening portion, a slitting groove and two receiving grooves, the sharpening knife a portion is disposed at one end of the base, and a side of the sharpening portion away from the base is a top end. The slit is formed on the sharpening portion, and an opening is formed at a top end and opposite sides of the sharpening portion. The grooves are disposed in the sharpening portion and are respectively located on opposite sides of the cutting groove, and each of the receiving grooves is in communication with the groove, and the surface of the second receiving groove away from the groove is defined as a limiting surface, and The at least one accommodating groove is provided with a through hole extending from the accommodating groove limiting surface to the outer side of the sharpening portion; a sharpening unit comprising two grinding blocks, wherein the two grinding blocks are respectively disposed in a receiving portion In the slot, the two-grinding block forms a V-shaped grinding groove at the slot of the base, and the side of the second grinding block away from the sharpening groove is defined as the adjusting side, and the adjusting sides of each sharpening block are Relying on a limiting surface of the accommodating groove provided therein; and, at least one adjusting unit, each adjusting unit includes a through shaft, each The adjusting unit is respectively disposed in a through hole of the base by the axially movable shaft.

In the sharpener as described above, preferably, the two sharpening blocks of the sharpening unit are pivotally connected to each other at the bottom end.

In the sharpener as described above, preferably, the sharpening unit is pivoted at a pivot and fixed to the base.

By the above technical means, the sharpener of the present invention can use the adjusting unit to change the angle of the V-shaped sharpening groove formed by the two-grinding block, so that the sharpener of the present invention can be used for different specifications of the blade; When the blade is worn out for a long period of time, the adjustment unit can also be used to maintain the gap of the sharp groove at a preset size.
