Abstract

PURPOSE: To make the easy controlling of the depth of cut possible for a worker by peeping a main body from above by a method wherein the displaying scale of the depth of cut is provided in a connecting part between a gear cover and a base. CONSTITUTION: In a portable circular saw, a base 2 is pivotally mounted to a gear cover 1 covering a saw blade 8 by means of a roll pin 6 and a hexagon socket head setscrew 7 in order to determine the depth of cut. At this time, in the connecting part with a base 2 of a gear cover 1, an indicating mark 3 for indicating the displaying scale 4 of the depth of cut in response to the depth of cut of a main body is provided. Through the pivoting of the base 2 about the roll pin 6 relative to the gear cover 1, the displaying scale 4 of the depth of cut provided on the gear cover 1 moves relative to the indicating mark 3 provided on the base 2, resulting in allowing to display the depth of cut of the main body. Thus, the controlling work of the depth of cut becomes easy and consequently the operability of a circular saw can be improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable circular saw having an improved cut depth display mechanism.

[0002]

2. Description of the Related Art An example of a conventional portable circle is shown in FIGS.
Shown in The portable circular saw includes a housing 5 for accommodating an electric motor (not shown), a saw blade 8 driven by the electric motor, a gear cover 1 for covering the saw blade 8, and a roll pin 6 for the gear cover 1.
It is configured to include a base 2 which is rotatably attached via a base 2, which enables adjustment of a cutting amount, a safety cover 9 which covers the saw blade 8 and is slidably attached depending on a cutting condition, and the safety cover 9 is further attached to the safety cover 9. Is marked with a scale 10 for displaying the cut amount. With the above configuration, in the portable circular saw, the base 2 is rotated around the roll pin 6 which is the connecting portion between the gear cover 1 and the base 2, and the lower end surface of the base 2 is set to the scale 10 engraved on the safety cover 9. By adjusting them, it is possible to adjust the cut amount without using a ruler or the like.

[0003]

In the conventional portable circular saw, the cut depth indicating scale 10 was provided on the safety cover 9. For this reason, in order to adjust the cutting depth, it is necessary to look into the main body from the side surface (saw blade 8 side) and to see the bottom surface of the base 2 and the scale 10 of the safety cover 9 at a right angle, so that the accuracy cannot be adjusted accurately. There is
The matching work was not easy. It is an object of the present invention to eliminate the above-mentioned drawbacks of the prior art and to improve this operability of a portable round.

[0004]

The above object can be achieved by providing a cut depth indicating scale and a scale indicating mark at the connecting portion between the gear cover and the base.

[0005]

In the portable circular saw configured as described above, the operator can easily adjust the cutting depth by matching the cutting depths at the connecting portion of the base and the gear cover, which is the peep of the main body. it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention is shown in FIGS. A housing 5 for housing an electric motor, a saw blade 8 driven by the electric motor, a gear cover 1 for covering the saw blade 8, a roll pin 6 and a hexagon socket set screw 7 rotatably attached to the gear cover 1 to determine the cut amount. The structure having the base 2 that operates is similar to the conventional circular saw. In the present invention, the notch depth display scale 4 is further provided at the connecting portion of the gear cover 1 with the base 2.
In addition to the above, an indicator mark 3 for indicating a cut depth display scale 4 according to the cut depth of the main body is provided at the connecting portion of the base 2 with the gear cover 1.

In the portable circular saw having the above-described structure, the base 2 rotates with respect to the gear cover 1 about the roll pin 6 as an axis, whereby the cutting depth provided on the gear cover 1 with respect to the instruction mark 3 provided on the base 2. The display scale 4 can be moved to display the cutting depth of the main body.

[0008]

According to the present invention, a scale for indicating the depth of cut is provided at the connecting portion between the gear cover and the base, so that the operator can easily adjust the depth of cut by looking into the main body from the upper portion. The operability of Marunouchi is improved.
