DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a circular saw, and particularly to a portable electric circular saw rather than a stationary 1A type.

The cutting depth of a circular saw is adjusted by rotatably connecting the main body case, which houses the saw blade and the t-tar that drives it, to a base that is placed on the soil surface of the material to be cut. This is done by changing the angle. FIG. 1 shows a conventional example. In the figure, i11 is a base, (2) is a main body case, and the main body case (2) is rotatably connected to the front upper surface of the base +1) by a shaft (6). Connect the fixed cover (7), which is attached to the main body case i2 and covers the saw blade (4), to any part of the adjustment plate (lO) protruding from the top surface with an adjustment twist of 0). (The connection angle between 11 and the main case (2) can be adjusted and fixed, so that the saw blade (4),

) is the material to be cut, and (8) is a rotating card that covers the saw blade (4) raised below the base (ll).By the way, in this conventional type, the handle (3) on the circular saw is Since the handle (3) is integrally provided with the case (2), there are the following problems: In such a circular saw, the handle (3) is made to form a certain angle α with the base ftl;
When cutting, apply a force F in the horizontal direction to the base (1) at the load point K of the handle (3) so that the component force F sin α of this force F becomes a vertical load that presses the base ttl against the material to be cut (9). However, if the handle (3) is provided at a position opposite to the main case (2), if the depth of cut is made shallow, the position iM at the load point will not be affected. The component force Fsinα, which is a vertical load, also becomes smaller, and the force with which the circular saw is pressed against the material to be cut (9), that is, the force that holds the circular saw, becomes weaker, making the circular saw more likely to wobble.

The present invention has been devised in view of these points, and its purpose is to keep the handle at a constant position with respect to the base even if the depth of illumination is changed (tiling it to maintain the charged point and vertical division). To provide a circular saw which is easy to use and can perform stable cutting work because the force does not change.

In the present invention, a handle is erected from a base that is placed on the surface of the object to be cut, and the saw blade and the saw blade are driven with respect to the base and the handle.
The feature is that the wooden case with 6'f:-9 is connected to the rotation mark, so that the handle does not move with the wooden case when it stops at the cutting depth of 4. , the base and handle are at the same angle. In this case, if the handle is provided with a sliding guide for the rotation of the main case, the connection strength between the handle and the wooden case will be increased, making cutting work easier and making it easier to adjust the cutting depth. This means that you can do it without any hassle.

The means for fixing the wooden case and the base at a certain connection angle is not by tightening adjustment screws as in the conventional example described in #J, but by using a large number of engagement plates on m-alignment plates set upright from the base. A structure in which a recess is formed and a caltrop is provided in the wooden case with a protrusion that engages with the engagement recess when the spring is biased provides good operability and fixation. preferred in terms of certainty.
