る。 (57) [Summary] [Problem] There are various types of chamfered planes for fire-resistant boards used in the construction industry, but the cuts are worsened during use, the roots are well rooted, and it takes time and effort. did. SOLUTION: The cutter knife (body) is characterized in that it has a sharp cutting edge, and has a size of about 8 mm in width and about 25 mm in height at the tip of a cutter knife (body). Work easier than chamfered canna.

Description

【考案の詳細な説明】この考案を図１を参考に説明する。[Detailed Description of the Invention] The invention will be described with reference to FIG.

（５）はカッターナイフの本体、（６）は本体より出し入れ自在突出した刃部である。 (5) is a main body of the cutter knife, and (6) is a blade portion protruding freely from the main body.

（３）はステンレス板あるいは樹脂で形成した定規で、案内穴（１）定板（４ａ）、（４ｂ）が形成されている。 (3) is a ruler formed of a stainless steel plate or a resin, in which guide holes (1) are formed with fixed plates (4a) and (4b).

定板（４ａ）は、定規（３）の上板部（７）との間に約４５度の角度を有している。（２）は定規（３）の取り付け位置を固定する固定ビスである。（８）は耐火ボード等の加工材である。 The plate (4a) has an angle of about 45 degrees with the upper plate (7) of the ruler (3). (2) is a fixing screw for fixing the mounting position of the ruler (3). (8) is a processed material such as a fireproof board.

そしてこの定規（３）案内穴（１）に刃部（６）を挿入し、定規（３）を本体（５）の先端部に一体化させて固定ビス（２）をもって固定する。このカッターナイフを使って加工材（８）の面とり加工を行う際には、定板（４ａ）、（４ｂ）を加工材（８）の面に当て、案内しながら図４に示すように引いて加工材（８）の面とりを行う。この様に作業をすると、切り口がきれいで根ずまりせず、従来使われてきたボード用面とりカンナよりも、使ってみて簡単で、効率の良い作業が出来た。従来の面とりカンナは根ずまりが多く調子合わせが大変で、手間暇をかけて来たが、この定規をカッターナイフと一体化する事で、ボード用面とりカッターナイフとなる。 Then, the blade (6) is inserted into the guide hole (1) of the ruler (3), and the ruler (3) is integrated with the tip of the body (5) and fixed with the fixing screw (2). When the work material (8) is chamfered using this cutter knife, the platens (4a) and (4b) are applied to the surface of the work material (8) and guided as shown in FIG. Pull and chamfer the processed material (8). By doing this, the cut was clean and did not get stuck, and it was easier and more efficient to use than the conventional board chamfered canna. The conventional chamfered canna has many roots and it is difficult to adjust the tone, so it takes time and effort. By integrating this ruler with the cutter knife, it becomes a chamfered knife for board.
