Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an improvement in the handle of a replaceable blade type cutlery. For example, handles for so-called replaceable-blade saws with replaceable blades, handles for replaceable-blade sickles with replaceable sickles, and handles for other blades with replaceable blades. It is about improvement.

BACKGROUND ART Regarding saws, various types of so-called replaceable blade saws with replaceable saw blades have been devised and actually commercialized.

For example, Japanese Utility Model Publication No. 57-26724 proposes a replaceable blade type saw in which the saw blade can be attached to the handle by holding the left and right sides of the rear end of the saw blade.

Further, Japanese Utility Model Publication No. 16084/1984 proposes a replaceable blade type saw handle that uses a fixing screw to fix the saw body.

Further, Japanese Utility Model Application Publication No. 143801/1983 proposes a replaceable blade type saw in which the saw blade is fixed using a buckle.

In addition, the replaceable blade type sickle includes those related to an earlier application by the applicant of the present application (Japanese Patent Application No. 139071/1980 and No. 76071/1999).

Problems to be Solved by the Invention Taking replaceable blade type saws as an example, conventional saw blade holding structures differ from product to product, and there is no compatibility between products. Therefore, a certain replaceable blade type saw has the drawback that it cannot be attached to a saw body (replaceable blade) unless it is the saw body (replaceable blade) for that type of replaceable blade type saw.

Furthermore, there are various types of sawfish depending on the purpose of its use. For example, a slightly thinner saw blade suitable for cutting decorative plywood and laminated wood, a slightly thicker saw blade suitable for cutting square timbers and logs, a saw blade with fine teeth for precision machining, and a thorn-toothed saw blade. There are various types such as meat, sawed meat of Edome tooth, and also,
There are various tooth lengths depending on the purpose. However, in conventional replaceable blade saws, the saw blades that can be attached to a given replaceable blade saw are limited to predetermined types of saw blades, so one replaceable blade saw can be used for different purposes. The drawback is that it is not possible to select a specific saw blade from among a wide variety of saw blades and then use the saw blade.

In addition, at saw shops, only the types of saws with replaceable blades have replacement blades (
It was also necessary to have a variety of grip handles for the replaceable blade saw itself. Therefore,
As the number of types of replaceable blade saws increases, the number of types of replaceable blades (saw bodies) and gripping handles also increases, making it difficult to keep them in stock, as well as increasing the amount of inventory space.

Similar drawbacks also apply to replaceable blade type cutlery tools other than replaceable blade type saws.

Therefore, the present invention has been made in order to eliminate the above-mentioned drawbacks.In a handle for a replaceable blade type cutlery, the holding structure portion of the blade is composed of an attachment, and the attachment is connected to the handle body (handle).

Further, it is preferable that the attachment is provided with a first tapered surface, and that the handle body is provided with a second tapered surface that comes into pressure contact with the first tapered surface when the attachment is pulled.

Furthermore, in the handle for each of the replaceable blade type cutlery, it is preferable that an anti-slip member having a large coefficient of friction is provided on the entire or partial surface of the handle main body.

The present invention also provides a holding means for holding a predetermined blade in a removable manner, a handle means for a user to hold the blade by hand, and a connecting means for removably connecting the holding means and the handle means. This is a handle for a replaceable blade type cutlery, characterized in that it includes .

In the handle for the replaceable blade type cutlery, the connecting means has a first tapered surface, a second tapered surface opposite to the first tapered surface, and presses the first tapered surface and the second tapered surface when connected. It is preferable that the device includes a tapered surface moving means that acts in the opposite direction when the connection is released.

Further, in each of the handles for the replaceable blade type cutlery, it is preferable that the handle means is provided with an anti-slip member having a large coefficient of friction on the entire or partial surface thereof.

Furthermore, the present invention is an attachment for a replaceable cutter, characterized in that it is equipped with a holding structure for holding a predetermined blade and is detachable from a predetermined handle.
