Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knife sharpener which sharpens a knife by fixing the blade to a grindstone surface at a sharpening angle to grind the knife flat and reciprocating the grindstone flat. It is.

[0002]

2. Description of the Related Art Conventionally, a knife has been gripped, and the cutting edge has been laid flat on a grindstone, and both sides have been visually polished with care so as not to form a round blade uniformly and sharply. On the other hand, while holding the knife by hand, apply the cutting edge to the stone of the electric grinder and sharpen the tip from the tip of the knife to the root while moving it by hand and visually moving it to the left and right.Since this grinding stone was not used except for medium rough grinding is there.

[0003]

This has the following disadvantages. (B) When the knife is gripped by hand and reciprocated on the grindstone, the blade edge is inevitably touched. In order to prevent this, it was necessary to take delicate care, effort and long experience. (B) When sharpening the kitchen knife with an electric grinder, apply the cutting edge to the grinder and move it to the left and right so that it becomes even and sharp from the tip of the kitchen knife to the root while moving it to the left and right with a round whetstone. It is impossible for amateurs who need long experience to sharpen well because the edge is sharpened flat. In addition, the grinding stone is one kind of medium rough grinding and the cutting edge does not become sufficiently sharp, it is a temporary make-up. The present invention has been made to solve the above drawbacks.

[0004]

A stand (12) is provided on one side of a knife sharpener (23) provided with an instrument leg (21).

A crank joint (20) is provided in the middle of the crankshaft (18), the joint is broken, and the crankshaft (18) reciprocates flatly from the place where the upper and lower three rotating pins (24) are broken. The connecting device of the grindstone placing table (22) is connected to the end of this shaft by the connecting pin (37) with the cushion material (31) interposed therebetween, and the cushion material (31) is prevented from falling off. The grinding liquid is provided in a grinding liquid dam (32) around the knife blade (23), and is collected in the grinding liquid reservoir (33) from one of the cuts. The present invention is a knife sharpener having the above configuration.

[0005]

Embodiments of the present invention will be described below. (A) To prevent rust, use aluminum, plastic, iron (painted) and wood. (B) Knife grinding table (23) provided with instrument legs (21)
A stand (12) is provided vertically at about one-third of one side, and a shoulder (1) having two elongated holes formed in parallel at right angles is provided at the end of the stand (12). (C) A long sliding hole (3) is provided in the vertical center of the arm (4) of the upper round bar from the shoulder (1) downward, and a bolt and a butterfly are provided in each of the two long holes of the shoulder (1). A shoulder joint (2) that can be fixed with a nut and moves up, down, left, and right is provided. (D) A first joint (5) is provided. This joint is composed of two flat plates, one fixed to the upper round bar arm (4) and the other fixed to the lower round bar arm (4). One pin hole at the center of the plate (34)
The other one is provided with pins (28) and inserted and turned left and right. Two flat plates are provided with left and right long holes (26), which are fixed with bolts and wing nuts (27). (E) A second joint (6) is provided. In this joint, the lower round bar arm (4) is inserted into the tube (25) and the upper and lower arms (4) are pinned to move the tube (25). Turn around the round bar and fix it with the thumb screw (10). (F) A third joint (7) is provided.
5) When the front and rear surfaces of the flat plate a (35) are flat and the thumb screw (30) is tightened through the tube (25) through the protrusion at the center front and rear, it is fixed to the tube (25) and loosened when both ends move up and down. Holes are provided one by one, below which fixing bolts are provided on the left and right sides of the flat plate b (36), and the elastic material (29) is inserted into the flat plate b (36).
The magnet (8) is provided in the lower center of the flat plate b (36), which is inserted into the holes at the left and right ends of (35) and adjusts the pressure of the elastic material (29) with the push wing nut (9). (G) The magnet (11) is mounted on the magnet mounting table (22), the wheels (14) are provided with the wheel mounting metal (13), the kitchen knife grinding table (23) is mounted, and the handle (16) is rotated manually or by power. (17) rotates and stops the crankshaft (1
9) The crankshaft (18) is prevented from rotating and reciprocates, and the crank joint (20) in the middle of the crankshaft (18).
The joints are broken and the upper and lower three rotating pins (24)
The crankshaft (18) reciprocates flatly from the place where it is broken by the work of the book. The connecting device of the grindstone mount (22) is connected to the end of this shaft by the connecting pin (37) with the cushion material (31) interposed therebetween. In addition, the cushion material (31) is prevented from falling off. (H) The magnet (11) is mounted on a whetstone mounting base (22) having an elastic packing attached to the surface, and is fixed with two whetstone holding thumb screws (15) from one side. (4) The rotating pin (24) is made of a tube outside the bottle. Each time the crankshaft (18) moves, the crank joint (20) acts to make pin contact and reciprocate the crankshaft (18) flat. Exercise. (G) The grinding liquid is provided in a grinding liquid dam (32) around the knife blade (23), and is collected in the grinding liquid reservoir (33) from one of the cuts. The present invention uses a whetstone (11) when using it in the above structure.
Soak the knives in water and use enough water. First, even if the knife (11) reciprocates the magnet (8) with the magnet (8), the handle will not hit the stand (12) so that the knife can be evenly polished. Magnetically loosen the thumbscrews at each joint to allow the joints to move freely. The angle at which the blade is brought into contact with the grindstone (11) at the first joint (5) is visually determined. If the angle is insufficient, the shoulder joint (2) is also used and fixed with the related thumb screw. Next, the position where the knife hits the grindstone (11) is determined by the second joint (6). Next, the position where the blade tip hits the grindstone (11) is determined by the third joint (7). Next, turn the handle (16) and check the quality of the touch position pressure on the grindstone (11) of the blade. If the angle is not sufficient, correct it with the push butterfly nut (9) and correct it with the first joint (5). Fix. Then, depending on the condition of the blades, rough grinding, medium rough grinding, and finishing grinding are used separately. When one side is polished, turn over and grind in the same manner as before. For long knives, grind the tip and then the base, so grind it in two steps. If one side is polished, turn it over and grind it. For heavy knives, use a flat plate b (36) with two magnets (8). Grinding, the grinding liquid is the grinding dam (32) around the knife blade (23)
From one of the cuts in the grinding fluid reservoir (33), no matter where the instrument is used, it does not stain the surroundings,
1) wears on average when used in reverse.

[0006]

According to the present invention, anyone can grind the tip of the kitchen knife flat, without soiling the floor, use the whetstone (11) properly depending on the broken state of the blade, and finally grind it with a finishing grinder. The grindstone (11), which has a sharp cutting edge to be used, can help households without having to relied on an expert who only needs to use what is in each household. Finally, besides the kitchen knife, the knife attached to this instrument is sharpened well. For example, only, plane, knife.
