Problems solved by technology

However, in order to allow the saw blade to tilt left and right relative to the cutting direction to perform so-called oblique cutting, the depth-of-cut guide is supported so that it can swing left and right relative to the base in the cutting direction. Angular wobble prevents accurate oblique cutting

Embodiment Construction

[0026] Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 4 . FIG. 1 shows a portable circular saw according to this embodiment. The portable circular saw 1 includes a base 10 and a circular saw main body 20 , wherein the base 10 is rectangular and contacts the upper surface of the workpiece W to be cut, and the circular saw main body 20 is supported on the upper surface side of the base 10 .

[0027] This portable circular saw 1 has a mechanism (parallelism adjustment mechanism 30 ) for adjusting the parallelism between the saw blade 21 of the circular saw body 20 and the guide surface 11 set at the side end portion of the base 10 . The characteristic part of the portable circular saw 1 of this embodiment lies in the parallelism adjustment mechanism 30. Other than that, the basic structure of the portable circular saw is the same as that of the prior art, and there is no special feature in this embodiment. changes, which are briefly e...

Abstract

The present invention provides a portable circular saw, which is a type in which the cutting depth of the saw blade is adjusted by swinging the saw blade guard up and down with the front side of the saw blade guard as the center. Problems such as shaking in the parallelism fine-tuning mechanism for adjusting the parallelism of the saw blade relative to the guide surface of the base. In the portable circular saw (1) of the type in which a depth-of-cut guide (15) for adjusting the depth of cut is disposed along the back (22a) of the blade guard (22), the rear of the blade guard (22) There is a cover fixing bolt (31) on the upper part, through the cover fixing bolt (31), the rear part of the saw blade guard (22) is fixed on the depth of cut guide (15), by adjusting the cover fixing bolt (31) in The position in the axial direction is used to adjust the position of the rear side of the saw blade guard (22) in the vertical direction of the saw blade surface, thereby adjusting the parallelism.

Description

technical field [0001] The invention relates to a portable circular saw, which is cut by a rotating circular saw blade (saw blade) while the user holds the portable circular saw and moves it along the cutting direction. Background technique [0002] This kind of portable circular saw has a base contacting the upper surface of the workpiece to be cut and a circular saw main body supported on the upper surface of the base, and the saw blade of the circular saw main body protrudes from the lower surface side of the base. The user moves the portable circular saw linearly along the cutting direction, and the saw blade protruding from the lower surface of the base cuts into the piece to be cut for cutting. [0003] Since the above-mentioned portable circular saw is made by the user to advance in a straight line, thereby cutting the piece to be cut straightly, in order to cut more accurately than in the prior art, the side end of the base in this portable circular saw is used as T...
