Abstract

(57) [Summary] [Object] The present invention relates to a jigsaw for cutting a round material, and an object thereof is to facilitate the cutting operation of the round material in the longitudinal direction. [Structure] The round material cutting base 2 of the present invention is formed in an inverted V shape by providing two inclined surfaces A and B on the bottom surface, and is provided with two contact portions 5 for contacting the round material 4. Is characterized by.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a jigsaw for cutting a round material.

[0002]

[Prior Art]

 Conventionally, when cutting a round material in the longitudinal direction using a jigsaw, the contact area between the base surface and the round material was small and unstable because the bottom surface of the base contacting the work material was flat. For this reason, the jig saw easily moved in the circumferential direction during the cutting work, making the cutting work difficult.

[0003]

[Problems to be solved by the device]

 Conventionally, when cutting a round material in the longitudinal direction with a jigsaw, the bottom surface of the base was in contact with the outer circumference of the round material, but because the contact area between the bottom surface of the base and the round material was small, stability was not obtained and cutting was performed along the black line. There was a problem that I could not do it. An object of the present invention is to solve the above problems and to provide a jigsaw capable of easily cutting a round material in the longitudinal direction.

[0004]

[Means for Solving the Problems]

 The above object is achieved by devising the shape of the bottom surface of the base so that the jigsaw oscillates due to insufficient contact area between the bottom surface of the base and the round material. That is, it is only necessary to provide two contact portions with the round material on the bottom surface of the jigsaw base.

[0005]

[Action]

 The jig cutting saw base with the above-mentioned structure for longitudinal cutting of round material increases stability by providing two contact points with the round material on the bottom surface of the base when the base is cut by abutting the outer circumference of the round material. As a result, the jigsaw body will not move in the circumferential direction during cutting.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. 2 and 3 show a front view and a bottom view of the round material cutting base 2. The bottom surface of the base 2, that is, the abutting surface of the work piece, is provided with inclined surfaces A and B inclined to both sides from the center line in the longitudinal direction to form an inverted V shape. FIG. 1 shows an embodiment in which a round material cutting base 2 of the present invention is attached. A base 2 is fixed to the main body 1, and a reciprocating blade 3 is attached to the main body 1. When cutting the round material 4 in the longitudinal direction, the base 2 may be brought into contact with the top of the round material 4 and cut as it is. FIG. 4 is a front view when the round material cutting base 2 is brought into contact with the round material 4. The round material cutting base 2 is in contact with the round material 4 by two contact portions 5 with the round material 4 by the inclined surfaces A and B provided on the bottom surface of the base 2. When the conventional base was used, the bottom surface of the base was flat, and only one contact point with the round material 4 was obtained, and the base easily moved in the circumferential direction of the round material 4. If the round material cutting base 2 of the invention is used, the reaction force of the round material 4 is received at the two contact portions 5, so that the round material cutting base 2 does not move in the circumferential direction of the round material 4. FIG. 5 is a front view when the base 2 is tilted, and shows a positional relationship between the round material 4 and the blade 3 when the round material cutting base 2 is tilted and attached to the jigsaw body 1. When the end of the round material 4 is cut using a conventional base, the base easily moves in the circumferential direction of the round material 4 because the bottom surface of the base is a flat surface, making it difficult to cut the jig. If the base 2 for cutting a round material of the present invention is arbitrarily inclined and attached, the end of the round material 4 can be easily cut.

[0007]

[Effect of the device]

 According to the present invention, the jigsaw can be stabilized on the outer circumference of the round material, and it becomes easy to cut the round material in the longitudinal direction, which was difficult in the past, so that the center line of the round material can be easily cut and the base can be easily cut. It becomes possible to easily cut the edge of the circle of the round material by inclining, and the range of the work pieces and processing method by the jigsaw is expanded.
