Abstract

PURPOSE:To raise the feeding stability of a jigsaw body at the time of inclination cutting and enhance the accuracy of a cut surface of a workpiece. CONSTITUTION:A handle part 2 is mounted on a jigsaw body 1 so that the jig saw body 1 can rotate about its axis. The handle part 2 is fixed thereto using bolts 3, 4 and nuts 5, 6. The handle part 2 is inclined reversely to the inclining direction of the jigsaw body 1 with respect to a base 7 so that the handle part 2 is positioned on the extension line of a part to be cut in a vertical direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jigsaw for cutting a material such as wood.

[0002]

2. Description of the Related Art In a conventional jigsaw, a handle portion 2 is fixed to a jigsaw main body 1. Therefore, when the main body 1 is tilted with respect to a base 7 and a material to be cut is cut obliquely, as shown in FIG. Since the handle portion 2 is separated from the extension of the cutting portion by the distance d in the direction, the feeding of the jigsaw main body 1 is unstable.

[0003]

In the conventional jigsaw, when a load is applied to the handle portion 2 at the time of slant cutting, the handle portion 2 is not located on the same line extending the cut portion of the material to be cut. There is a problem that the feed becomes unstable and the cutting surface accuracy of the material to be cut is deteriorated. An object of the present invention is to solve the above problems, increase the stability of the main body with respect to feed during inclined cutting, and improve the cutting surface accuracy of the material to be cut.

[0004]

[Means for Solving the Problems] The above object is to handle the jigsaw body as a shaft so that when the jigsaw body is tilted with respect to the base, the handle portion is aligned with the same line extending the cut portion in the vertical direction. This is achieved by rotating and fixing the part. The above object can be achieved even if the handle portion is integrally formed with the base.

[0005]

In the jigsaw configured as described above, the handle portion is aligned with the cutting portion in the vertical direction during inclined cutting, so that the main body can be fed stably.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIGS. 1 and 2, the jigsaw body 1 and the handle portion 2 are connected by bolts 3 and 4 and nuts 5 and 6 provided inside the jigsaw body 1. By loosening the bolts 3 and 4, the handle portion 2 is It becomes rotatable with respect to the jigsaw body 1 about a straight line connecting the points 3 and 4, and is fixed to the jigsaw body 1 by tightening the bolts 3 and 4.

FIG. 3 is a view showing a state of the jigsaw constructed as described above at the time of inclined cutting, that is, a state in which the jigsaw main body 1 is inclined with respect to the base 7. First, with the handle portion 2 fixed to the jigsaw body 1, the body 1
When the angle is inclined a with respect to the base 7, the position at which the jigsaw body 1 is pressed against the material 8 to be cut in the direction of the arrow at the time of cutting and the cutting portion are horizontally separated by a distance b. Therefore, when the bolts 3 and 4 are loosened from this state and the handle portion 2 is fixed to the jigsaw body 1 by tilting the angle c in the opposite direction as shown by the broken line, the jigsaw pressing position 9 and the cutting portion are substantially aligned in the vertical direction, That is, since the handle portion 2 comes to be positioned on the extension line of the cutting portion, the inclined cutting work can be stably performed.

4 and 5 show another embodiment of the present invention.
The base 7 attached to the lower part of the jigsaw body 1 is provided with a handle part 11 integrated with a base at the rear end portion 10 independently of the jigsaw body 1 with respect to the cutting direction arrow. When performing cutting by tilting the main body 1 with respect to the base 7 with the jigsaw having such a configuration, the base integrated handle 11 is always positioned perpendicular to the cutting point, regardless of whether the jigsaw main body 1 is tilted left or right. Therefore, the jigsaw can be fed very stably even at the time of inclined cutting, so that the workability is improved and the cutting accuracy can be improved.

[0009]

According to the present invention, since the handle portion is aligned with the cutting portion in the vertical direction during inclined cutting, the main body can be stably fed when cutting the material to be cut,
The cutting surface accuracy can be improved.
