Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blade for a portable circular saw blade.

[0002]

2. Description of the Prior Art A conventional circular saw blade plate according to the prior art will be described with reference to FIGS. As shown in FIG. 1, in the prior art, a saw blade 1, which is driven by a motor,
FIGS. 7 to 9 show a portable circular saw composed of a saw cover 2 covering the saw blade 1, a housing 3 containing the motor, and a base 4 for guiding the saw blade 1 when cutting.
As shown in FIG.
A blade port plate 5 is buried in the vicinity of the blade port 11 so as to be slidable in the direction of the arrow in FIG. FIG.
As shown in the figure, the blade plate 5 is sandwiched between the base 4 by a countersunk screw 6 and a nut 7. And on base 4,
A guide groove 8 for guiding the flathead screw 6 is provided.

[0003]

As shown in FIG. 11, a cutting edge plate 5 of a conventional portable circular saw is provided with a cutting 10 or the like generated when a portable circular saw is used. There is a problem that the blade plate 5 is accumulated in the guide groove 8 of the blade screw 6 for holding the blade plate, making it difficult to adjust the blade plate 5. An object of the present invention is to eliminate the above problems and improve the operability of a blade plate in a portable circular saw.

[0004]

The above object is achieved by forming a chip escape hole at an arbitrary position in a guide groove of a blade screw for holding a blade plate which is formed on a base of the blade plate. .

[0005]

In the portable circular saw constructed as described above, the chips collected in the guide grooves of the flat blade screws for holding the blade plate of the base are discharged from the chip escape holes provided in the blade plate. Therefore, the operation of the blade plate can be surely performed.

[0006]

1 to 5 show an embodiment of the present invention. FIG.
As shown in FIG. 2, a portable blade comprising a saw blade 1 driven by a motor, a saw cover 2 covering the saw blade 1, a housing 3 containing the motor, and a base 4 for guiding the saw blade 1 during cutting. In a circular saw, as shown in FIGS. 2 to 4, a cutting edge 1 from which the saw blade 1 projects
In the vicinity of the cutting edge 11, a cutting edge plate 5 is embedded so as to be slidable in the direction of the arrow in FIG.

[0007] As shown in FIG. 5, the blade plate 5 is held between the base 4 by a countersunk screw 6 and a nut 7. A guide groove 8 for guiding the countersunk screw 6 is formed in the base 4. Further bored the escape hole 9 of chips 10 in any position you pairs countercurrent into the guide groove 8 of the base 4 for blade edge plate 5 sandwiched bored on flathead 6 on the blade edge plate 5. In the circular saw having the above-described configuration, in the operation of adjusting the blade edge plate 5, the chips 10 accumulated in the guide grooves 8 of the flat screws 6 are discharged by the relief holes 9 of the chips 10. The adjustment work of the blade plate 5 becomes smooth.

[0008]

According to the present invention, according to the present invention, a relief hole for cutting chips or the like that accumulates in a flat screw guide groove for holding the blade plate is formed on the blade plate of the portable round blade. It is possible to discharge chips collected in the guide groove for holding the blade plate.
