Description

[Detailed Description of the Invention] The present invention relates to a device for fixing the base of a kitchen knife by driving a wedge from the rear surface.

The conventional method of attaching a knife's cap was to drill holes in the cap and handle attachment core, insert rivets, secure the knife in place, and then grind the knife. It is difficult to grind the ferrules when they are connected in a row, and the blade and handle parts other than the ferrules are often ground, resulting in defective products.Also, the rivets appear on the surface of the ferrules, making it difficult to see the aesthetics. It was a loss.

The present invention has been devised to eliminate the above-mentioned drawbacks, and will be explained below with reference to the drawings.

A groove 6 which extends from the front surface 4 to the rear surface 5 with a width in which the handle attachment core 3 is centered from the back 2 of the cap 1 and is fitted.
The front face 4 has a groove 8 of a slight depth downward along the groove 6, and the rear face 5 has a hole 9 centered around the groove 6. is formed at a position slightly below the center and facing the front surface 4, and a notch is formed at the lower part of the position where the cap 1 of the handle attachment core 3 is attached to a shape in which the connecting portion 7 of the cap 1 is fitted from below. A notch 10 is provided above, and a notch 11 is provided at a position that matches the hole 9 provided in the rear surface 5 of the cap 1, and a notch 11 that matches the inner surface of the hole 9.
The cap mounting structure is such that the shaft 12 is driven into the hole 9 as a wedge and fixed.

Since the present invention has the above structure, the handle attachment core 3
By fitting the connecting part 7 of the cap 1 from below into the notch 10 of the cap 1, the shaft 12 is inserted into the hole 9 together with the notch 11 that matches the hole 9 provided on the rear surface 5 of the cap 1.
By driving it in as a wedge, firmly attach the cap 1.
is fixed.

This invention does not require the installation work or grinding work of the knife with the knife blade attached, as was the case with conventional knives. Because it is manufactured separately, the grinding work is not dangerous, and it is possible to produce a uniform product with accurate work without damaging the other continuous blades or handles. Since it is completed by hammering it in, this work can be done easily by women and girls, and it can now be done even if you are not a craftsman who performs the traditional crimping work.
