されて締付けられ、固定される。The mounting receiving part 5 of the saw blade mounting part 3, the holding plate 6, and the saw blade 2
Two through holes 9 and 10 are bored in the root portions of the holes, respectively. Mounting receiving part 5. Holding plate 6 and saw blade 2
The root portions of the screws are stacked one on top of the other, and fixing screws 11 and 12 are communicated with the through holes 9 and 10, respectively, and are tightened and fixed.
この実施例では、装着受部５の透孔９および１０は、そ
の内周面にねじが形成されてねじ孔とされ、ビス１１お
よび１２の先端のねじが螺合するようにされている。In this embodiment, the through holes 9 and 10 of the mounting receiving part 5 have threads formed on their inner circumferential surfaces to form screw holes, into which the screws at the tips of the screws 11 and 12 are screwed.
このような構成に代え、ボルトおよびナツトを用いて、
装着受部５．のこ身２の根元部分および押え板６を固定
してもよい。Instead of this configuration, using bolts and nuts,
Mounting receiving part 5. The root portion of the saw body 2 and the presser plate 6 may be fixed.
また、固定ビスは必ずしも複数個必要なわけではなく、
１個で固定できるような構成にしてもよい。Also, multiple fixing screws are not necessarily required.
It may be configured such that it can be fixed with just one piece.

産工程において歩留がよい。Moreover, since the frame 13 and the mounting receiving part 5 are integrally formed, the saw blade mounting part 3 is not distorted with respect to the grip part 4, and the saw blade 2 can be held extremely accurately. Moreover, since the position of the saw blade 2 with respect to the grip portion 4 does not vary from product to product while the saw blade 2 is being held, the yield is good in the production process.
この実施例では、グリップ部４は、骨子１３と被覆部材
１４とで構成されているが、被覆部材１４は必ずしも必
要ではなく、骨子１３の表面がそのままグリップ部４の
表面となっていてもよい。In this embodiment, the grip part 4 is composed of a skeleton 13 and a covering member 14, but the covering member 14 is not necessarily necessary, and the surface of the skeleton 13 may directly serve as the surface of the grip part 4. .
また、被覆部材１４は、この実施例のように、骨子１３
全体を覆っている必要はなく、骨子１３を部分的に覆っ

覆部材１４が嵌め込まれているような構成でもよい。In addition, the covering member 14 has the skeleton 13 as in this embodiment.
It is not necessary to cover the entire skeleton 13, and the skeleton 13 may be partially covered. That is, the covering member 14 may be ring-shaped or cylindrical. In that case, a configuration may be adopted in which a recess is partially provided on the surface of the frame 13 and the covering member 14 is fitted into the recess.
また、上述の実施例では、装着受部５に対して押え板６
は取外し自在としたが、第５図に示すよぅに、押え板６
は装着受部５に対して開閉自在な構成でもよい。Further, in the above-described embodiment, the presser plate 6 is
is removable, but as shown in Figure 5, the presser plate 6
may be configured to be openable and closable with respect to the mounting receiving portion 5.
すなわち、装着受部５の根元部分と押え板６の根元部分

え板６を開成させればよい。That is, if the base portion of the mounting receiving portion 5 and the base portion of the presser plate 6 are rotatably engaged by the engagement pin 15, the presser plate 6 will rotate around the engagement pin 15. It can be opened and closed with respect to the mounting receiving part 5. Therefore, when replacing the saw blade 2, it is sufficient to remove the fixing screws 11 and 12 and open the presser plate 6.
なお、固定ビスは２個とせず、１個で固定できる構成や
３個で固定する構成としてもよい。Note that the number of fixing screws is not limited to two, but may be fixed with one or three fixing screws.
上述の説明は、剪定鋸を取上げて説明したが、この発明
は、手引鋸の柄に広く利用することができる。Although the above description has been made with reference to a pruning saw, the present invention can be widely used in handles of hand saws.
〈発明の効果〉
この発明は、以上のように構成されており、寸法の狂い
がなく、耐久性のよい替刃鋸の柄とすることができる。<Effects of the Invention> The present invention is configured as described above, and it is possible to provide a handle for a replaceable blade saw with no dimensional deviation and good durability.
また、骨子を被覆部材で覆えば、滑り止め効果が向上し
、より使い易い替刃式鋸の柄とすることができる。Moreover, if the skeleton is covered with a covering member, the anti-slip effect is improved and the handle of the replaceable blade type saw can be made easier to use.
この発明は、のこ身保持部がコンパクトにでき、特に、
柄が比較的短い、片手で作業する剪定鋸の柄等に好適な
柄とすることができる。In this invention, the saw body holding part can be made compact, and in particular,
The handle is relatively short and can be suitable for use with a pruning saw that is operated with one hand.
