Description of the Related Art Conventionally, when a blade is attached to or detached from a blade, a protrusion or the like attached to each end of the blade is hooked on a main body, and the blade is fixed by tightening a screw incorporated in an upper portion or a handle portion. However, this involves the work of closing one end with a screw while supporting one end with one hand, so it is extremely unstable during the work of turning the screw. It was difficult for unfamiliar people to handle it, as it became loose during cutting.

【課題を解決するための手段】課題を解決するために
は、ネジに代わって刃を引き上げて固定するものが必要
である。しかも刃の固定に手間や時間がかかってはなら

の結果、開閉式の留め金具を本体のアーム等の端に据え
付け、その留め金具の一端に刃を引っ掛け、可動部分を
起こしたり倒したりするだけで、刃を着脱する方法を発
見した。In order to solve the problem, it is necessary to raise and fix the blade in place of the screw. In addition, it is necessary that the blade must not be troublesome or time-consuming, and it must be easy for even beginners to handle.However, as a result of consideration, the openable fastener is installed on the end of the arm of the main body, and the I found a way to attach and detach the blade simply by hooking the blade at one end and raising or lowering the movable part.

足し、その上で金具を取り付けた。DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to carry out the present invention, a prototype of an existing thread saw to which an open-and-close type fastener is attached was manufactured. However, the existing jigsaw had a thin arm and could not fix the bracket sufficiently, so metal was added to widen only the upper part, and the bracket was attached on top.

簡単にし、刃の着脱の煩わしさを軽減したので、誰でも
簡単に糸鋸を使うことが出来、作業能率も上がる。Since the present invention has the above-described structure, the use of a thread saw, which is considered to be difficult for a layman to handle, has been simplified, and the trouble of attaching and detaching the blade has been reduced. You can easily use a thread saw and work efficiency will increase.
