形するといつた欠点があつた。 Conventionally, a splitting blade 1 of a portable circular saw machine is fixed to a splitting blade holding part 4 of a fixed cover 3 with a screw 2.
The split blade holding portion 4 is integrally formed with the fixed cover 3. Furthermore, the amount of protrusion of the saw blade 10 that protrudes below the surface plate 13 can be changed by the link 6 attached to the surface plate 13 with a pin 19 and the fastener 21 that operates integrally with the fixed cover 3. The structure allows for In the conventional example shown in FIG. 1, the fixed cover 3 is usually molded using a mold such as die-casting or plastic molding, and the mold for forming the internal space 20 for storing the saw blade 10 and the like is designed to be pulled out in the direction of arrow a. ing. For this reason, the split blade holding part 4
can only be formed over a wide range from the lower end A of the fixed cover 3 to near the chip discharge part 5, and a wasted part is molded on the chip discharge part 5 side of the split blade holding part 4, which increases the weight. It is the cause of In order to use the fixed cover 3 having such a shape and attach the link 6 to the inner wall B side of the fixed cover 3, the second
As shown in the figure, it is necessary to increase the width c of the fixed cover 3. If the width C were increased, the weight would increase, so normally the link 6 can be slid on the outer wall D side of the fixed cover 3. A structure that can be attached to is proposed. But like this link 6
When attached to the outer wall D of the fixed cover 3, if the height H of the fixed cover 3 is lowered, the upper end E of the link 6 will protrude from the F side of the fixed cover 3, so the arrow b
There was a drawback that the link 6 was easily deformed because it was easily subjected to directional forces.

ことができ、第１図のような固定カバー３と比較
し、小形・軽量ができるが、反面、固定カバー７
と固定カバー８はネジ９により止められているだ
けなので、強度的に弱いという欠点があつた。 In another conventional example shown in FIGS. 3 and 4, the fixed cover 3 is constructed by molding a fixed cover 7 and a fixed cover 8 separately and integrating them with screws 9. With the fixed cover 3 having such a structure, the split blade holding part 4 can be made smaller in relation to the direction of mold removal during molding, and the split blade 1 attachment position of the split blade holding part 4 and the tightening tool can be made smaller. Since there is no need to mold the split blade holding part 4 between the splitter blade 21 and the link 6, the link 6 can be attached to the inner wall B side, and compared to the fixed cover 3 shown in FIG. 1, it can be made smaller and lighter. On the other hand, fixed cover 7
Since the fixed cover 8 is only fixed with screws 9, it has a disadvantage of being weak in strength.
第５図において、固定カバー３に矢印ｅ方向の
力が加わつた場合、固定カバー３は二点鎖線で示
すように成形し、割刃１は固定カバー３の変形に
伴つて変位する。 In FIG. 5, when a force in the direction of arrow e is applied to the fixed cover 3, the fixed cover 3 is shaped as shown by the two-dot chain line, and the splitter blade 1 is displaced as the fixed cover 3 is deformed.
この為、割刃１とのこ刃１０との中心位置１１
がずれるので、木材切断時、機体１２の送りが重
い、木材切断ができないという問題が生ずる。 For this reason, the center position 11 between the split blade 1 and the saw blade 10 is
As a result, when cutting wood, the problem arises that the feed of the machine body 12 is heavy and wood cannot be cut.
また、のこ刃１０と定盤１３との平行度１が狂
う為、まつすぐに切断できないという問題も生じ
る。 Furthermore, since the parallelism 1 between the saw blade 10 and the surface plate 13 is out of alignment, a problem arises in that the saw blade cannot be cut immediately.
本考案の目的は、上記した従来技術の欠点をな
くし、小形・軽量でしかも強度を有する携帯用丸
のこ機を提供することにある。 An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to provide a portable circular saw machine that is small, lightweight, and strong.
本考案は、固定カバーと割刃保持部とを別体と
すれば、固定カバーの強度を低下させることなく
小形．軽量化できることに着目し、固定カバー、
割刃保持部材の構造を工夫したものである。 In this invention, by making the fixed cover and split blade holding part separate, the fixed cover can be made smaller without reducing its strength. Focusing on the fact that it can be made lighter, fixed covers,
The structure of the split blade holding member has been devised.
本考案の一実施例を図によつて説明する。 An embodiment of the present invention will be described with reference to the drawings.

ている。 In FIG. 7, the mold for forming the internal space 20 for storing the saw blade 10 and the like of the fixed cover 3 has a structure that is pulled out in the direction of arrow a, and the split blade holding member 14 is attached to the inner surface of the fixed cover 3. It is fixed with screws 15.

２により固着されている。 In FIGS. 6 and 8, the surface plate 13 is connected to a pin 17 via a hinge 16 attached to its tip.
It is rotatably connected to the front end of the fixed cover 3 by. The saw blade 10 is rotated by a motor built into the housing 18. By rotating the surface plate 13 about the pin 17, the amount of protrusion of the saw blade 10 from the lower surface of the surface plate 13 is changed, and the so-called depth of cut is changed. The link 6 is connected to the surface plate 13 by a pin 19, operates integrally with the surface plate 13, and is slidably attached to the inner wall B side of the fixed cover 3. The split blade 1 is fixed to a split blade holding member 14 with screws 2.

By making the fixed cover 3 and split blade holding member 14 separate, the fixed cover 3 can be made without being divided, so the strength of the fixed cover 3 is not reduced.
Furthermore, since there is no wasteful splitting blade holding portion caused by molding, the fixed cover 3 and the splitting blade holding member 14 can be made smaller and lighter. Fixed cover 3
Even if an external force is applied in the direction of arrow e (see FIG. 5), the fixed cover 3 will not easily deform. Therefore, the splitting blade 1 is also difficult to displace. Furthermore, since the parallelism between the saw blade 10 and the surface plate 13 does not easily become distorted, efficient wood cutting work can be performed. Further, since the link 6 is attached to slide on the inner wall B side of the fixed cover 3, it will not be deformed by external force.

で、能率の良い切断作業ができる。 According to the present invention, since the fixed cover and the split blade holding member are made separate, there is no need to separate the fixed cover, and there is no need for a wasteful split blade holding portion caused by molding. Therefore, the fixed cover can be made smaller and lighter without reducing its strength, allowing efficient cutting work.
