Abstract

Device for sharpening the blade of the knife includes a stand on which the mechanisms for adjusting the angle of sharpening and fixing of the knife, a mechanism for fixing the abrasive element connected to the mechanism for adjusting the angle of sharpening. Additionally equipped with a rotary mechanism, rotatable around its axis, which is connected by screws to the stand and the mechanism of fixing the knife.

Description

The utility model belongs to metalworking, in particular to a hand tool for sharpening the cutting edges of knives and can be used for sharpening kitchen knives.

A known device for sharpening the cutting edges of kitchen knives, which contains: a mechanism for fastening the knife, a mechanism for fastening an abrasive element, as well as a mechanism for adjusting the sharpening angle (US Patent Mo 4538382, IPC 8248 3/52, publication date 09.3.19851|.

The disadvantage of this device is the impossibility of precise adjustment of the sharpening angle of the knife blade on both sides, since to sharpen the blade from the other side, you need to move the mechanism for attaching the abrasive element to the other side of the sharpening angle adjustment mechanism - which greatly complicates the sharpening process and affects the cutting edge of the knife.

The closest analogue is a professional cutlery sharpener, which contains: a stand (base), a mechanism for adjusting the sharpening angle, a mechanism for attaching an abrasive element (a bar), as well as a mechanism for fixing a knife. US patent

Mo 5185958, IPC B248B 7/00, publication date 02/16/1993).

However, this device has a significant drawback; to sharpen the knife from the other side, it must be removed from the clamping mechanism and turned over to the other side, which causes additional difficulties when sharpening the knife, related to the correctness of the sharpening angle.

The useful model is based on the task of improving the device for sharpening the knife blade by changing its design, which allows: to sharpen the knife blade from both sides, without removing the knife from the clamping mechanism, which will ensure the uniformity of sharpening the knife blade from both sides, and will simplify and reduce labor intensity sharpening process.

The task is solved by a device for sharpening a knife blade, which contains a stand (base) on which mechanisms for adjusting the sharpening angle of fixing the knife are installed, the mechanism for fixing the abrasive element, connected to the mechanism for adjusting the sharpening angle, according to the useful model, is additionally equipped rotary mechanism, made with the possibility of rotation around its axis, which is connected with the help of screws to the stand and the mechanism for securing the knife.

The use of a device for sharpening a knife blade in combination with all essential features, including excellent allows you to sharpen a knife blade from both sides, without removing the knife

Zo from the clamping mechanism, excluding additional difficulties in sharpening the knife, associated with the correctness of the sharpening angle, which ensures uniformity of sharpening of the knife blade on both sides, and simplifies and reduces the laboriousness of the sharpening process.

The essence of the useful model is explained by the drawing, which shows the general view of the device for sharpening the knife blade.

The device for sharpening the knife blade includes a mechanism 1 for fixing the abrasive element, a mechanism 2 for adjusting the sharpening angle, a stand (base) C, a rotary mechanism 4, and a mechanism 5 for fixing the knife, screws (not shown in the drawing)

The mechanism 1 for fixing the abrasive element is connected to the mechanism 2 for adjusting the sharpening angle by a threaded connection, the internal thread is made in the rod of the mechanism 2, and the external thread is made in the rod of the mechanism 1. The mechanism 2 for adjusting the sharpening angle is connected to the stand (base) With a threaded connection - the internal thread is made in the stand 3, and the external thread is made in the rod of the mechanism 2 for adjusting the sharpening angle. The stand C is connected to the rotary mechanism 4 by two screws. Rotary mechanism 4, connected to mechanism 5 for fixing the knife, with screws.

A knife sharpener works like this. The device is installed on any horizontal surface, on a stand (base) 3. The knife is fixed in the knife fixing mechanism 5, the knife is fixed in the mechanism with screws. An abrasive element (bar) is attached to the mechanism 1 for fastening the abrasive element, and the angle necessary for sharpening is set on the mechanism 2 for adjusting the sharpening angle. The knife is sharpened on both sides, thanks to multiple rotations of the rotary mechanism 4, connected by screws, to the mechanism 5 for fixing the knife, thanks to which, additional difficulties in sharpening the knife, related to the correctness of the sharpening angle, are excluded.
