[0001]

[Industrial applications]

 The present invention relates to a handheld cutting tool for an electric cutting tool, which can easily cut a material such as wood along a cutting line by using an electric cutting tool such as an electric circular saw or a jigsaw.

[0002]

[Prior art]

 When cutting wood or the like with a hand-held electric cutting tool, such as an electric circular saw or a jigsaw, it is difficult to cut straight along the cutting line, and skill is required.

For this reason, as shown in FIGS. 9 and 10, a fixed wood 2 is placed on the upper surface of a material 1 to be cut such as wood, and a base 4 on the bottom surface of an electric cutting tool 3 is placed along the fixed wood 2. Cutting along the cutting line 14 has also been performed conventionally.

[0004]

[Problems to be solved by the device]

 However, as described above, there is a problem that an error occurs between the cut surface actually cut and the cutting line drawn on the material to be cut even if the cutting is performed using the fixed wood.

Since there is a distance between the cutting blade and the base end of the hand-held electric cutting tool along the fixed tree, the fixed tree is cut so that the cutting blade is located on the cutting line. It must be mounted with a register at a position separated from the line by the distance between the end of the base and the cutting blade, and it is difficult to determine the position.

When cutting a material such as wood with a hand-held electric cutting tool, move the hand-held electric cutting tool along the cutting line while holding the material to be cut with the base of the bottom surface of the hand-held electric cutting tool. ing. Therefore, the surface of the material to be cut may be damaged by the base of the hand-held electric cutting tool.

Further, when cutting a material to be cut with the hand-held electric cutting tool as described above, the material to be cut is held by the base on the bottom surface, but the base and the cutting blade are separated from each other. Therefore, it cannot hold the edge of the cutting line. For this reason, scabs and whiskers were likely to occur at the cut edges of the material to be cut.

In view of this, the present invention can accurately cut a material to be cut along a cutting line, does not damage the surface of the material to be cut at the time of cutting, and causes a blister or a whisker at the cut end. It aims to be able to cut the material to be cut without.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, in this invention, the backing plate placed on the upper surface of the material to be cut and having one side along the cutting line of the material to be cut comes into contact with the end surface of the base of the hand-held electric cutting tool. The guide surface of the fixed wood member, which is in contact with the base, is parallel to one side of the patch plate along the cutting line of the material to be cut, and from the guide surface of the fixed wood member to the above fixed plate. The distance to one side and the distance from the cutting blade of the hand-held electric cutting tool to the end face of the base are the same, and the fixed wood member is provided on the upper surface of the backing plate.

Further, the pad plate may be made of a cuttable member.

Further, at this time, the fixed wood member on the upper surface of the pad plate may be formed so as to be movable in parallel with one side of the pad plate along the cutting line of the material to be cut.

[0012]

[Action]

 In the handheld electric cutting tool constant tree thus constructed, the distance from one side of the backing plate to the constant wooden member and the distance from the base end surface of the cutting tool to the cutting blade are formed to be the same. Therefore, one side of the backing plate is along the cutting line on the material to be cut, the cutting tool is placed on the backing plate along the one side, and the cutting tool is used as a fixed wood member. When moved along, the material to be cut is cut along the cutting line.

Further, during this cutting, since the cutting tool moves on the backing plate, the base does not directly contact the surface of the material to be cut, the surface is not scratched, and the edge of the cutting line is close. Since it is pressed by one side of the backing plate, it prevents the blade from flipping up at the time of cutting and does not cause whiskers or whiskers at the cut end.

On the other hand, in the case where the pad plate is made of a severable member, the cutting tool is placed on the pad plate prior to use, and the placed cutting tool is moved along the joist member. By cutting the backing plate, one of the backing plates having a distance from the guide surface parallel to the guide surface of the fixed wood member and the same distance from the cutting edge of the cutting tool to the base end surface at the cut end. Form a side.

On the other hand, in the case where the fixed wood member on the upper surface of the backing plate is movably provided in parallel with one side of the backing plate along the cutting line, the distance between the fixed wood member and one side of the backing plate is small. By adjusting the above, the standard wood can be used for the cutting tools having different distances between the base end surface and the cutting blade. In addition, when one side of the backing plate becomes short due to run-out of the cutting blade during use of the above-mentioned fixed tree, the distance between the fixed tree member and one side of the backing plate should be adjusted. Thus, the distance can be always matched with the distance between the base end surface of the cutting tool and the cutting blade.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 3, the fixed wood for a hand-held electric cutting tool of the first embodiment (hereinafter referred to as a cutting fixed wood) includes a backing plate 10 placed on a material 1 to be cut and a hand-held electric cutting tool 3. It comprises a fixed wood member 12 having a guide surface 11 with which an end surface 6 of a base 4 provided on the side of the cutting blade 5 abuts.

The pad plate 10 is formed by forming, for example, a wood plate or a resin plate into an L shape that can be cut by the hand-held electric cutting tool 3, and a side edge of the L shape that extends in the lateral direction, that is, 13 in FIG. One side is formed in a straight line so as to be along the cutting line 14 drawn on the material 1 to be cut. A fixed wood member 12 is mounted on the pad plate 10.

The constant wood member 12 is parallel to the one side 13 of the pad plate 10, and the distance between the one side 13 and the guide surface 11 of the constant wood member 12 is the cutting constant wood. It is attached to the bent portion of the backing plate 10 where the distance between the cutting blade 5 of the electric cutting tool 3 to be used and the end face 6 of the base is the same.

Further, a square bar 16 is attached to the backing plate 10 along a back surface end portion 15 which is orthogonal to the one side 13, and the square bar 16 has a material to be cut 1 as shown in FIG. Engages with the side edges of the to prevent movement of the tree when cutting.

This embodiment is configured as described above. For example, as shown in FIGS. 3 and 4, the electric circular saw 3 cuts along the cutting line 14 drawn on the wood board 1. In this case, a cutting standard wood having the same distance between the base end surface 6 of the electric circular saw 3 and the cutting blade 5 and the distance from the guide surface 11 of the constant wood member 12 to the one side 13 of the backing plate 10 is used. The lumber 16 at the back end of the backing plate 10 placed on the wood plate 1 is placed in contact with the side edge of the wood plate 1, and Align one side 13 with the cutting line 14 described above, place the circular saw 3 on the caulking plate 10 along the line 14, and guide the base end face 6 of the circular saw 3 on the side of the cutting blade 5 to the fixed wood member 12. When the circular saw 3 is brought into contact with the surface 11 and, for example, puts a hand on 17 in the drawing and moves the circular saw 3 on the backing plate 10 along the guide surface 11, The movement path of the cutting blade 5 of the circular saw 3 and the cutting line 14 coincide with each other, and the wood board 1 can be cut along the cutting line 14. At this time, it is pressed by the one side 13 of the backing plate 10 just before the cutting line 14, and the cutting blade 5 prevents flipping up at the time of cutting, so that the cutting edge 18 does not cause whisker or whiskers. .

At that time, since the circular saw 3 moves on the backing plate 10 and the base 4 on the bottom of the circular saw 3 does not directly move on the wooden plate 1, the surface of the cut wooden plate 1 is damaged. Not attached.

As described above, this cutting tree is a cutting tree so that the cutting blade 5 of the hand-held electric cutting tool 3 is located on the cutting line 14 only by arranging the one side 13 along the cutting line 14. Can be easily positioned, and the cut surface 18 after cutting is not covered with whiskers or scratched.

In the second embodiment shown in FIG. 5, the pad plate 10 is formed of, for example, a wood plate, a resin plate or the like that can be cut by the hand-held electric cutting tool 3, and the pad plate 10 is moved from the guide surface 11 of the fixed wood member 12 to the pad plate 10. The distance to one side 13 is larger than the distance from the cutting blade 5 of the hand-held electric cutting tool 3 to the base end surface 6. In such a structure, the hand-held electric cutting tool 3 is placed on the backing plate 10, the base end surface 6 of the tool 3 is brought into contact with the guide surface 11 of the fixed wood member 12, and the hand-held electric cutting tool is provided along the guide surface 11. By moving the cutting tool 3 and cutting the abutting plate 10, the cutting surface of the cutting tool 3 is parallel to the guide surface 11 and is equal to the distance from the cutting blade 5 of the cutting tool 3 to the base end surface 6. One side 13 of the backing plate 10 is formed along the cutting line 14 having a distance of.

Therefore, for example, when a cutting tree provided with a large-sized pad plate 10 is made, various kinds of cutting tools having different distances between the base end face 6 and the cutting blade 5 are simply cut. It can be used as a cutting stub for the hand-held electric cutting tool 3, and it is not necessary to prepare different cutting stubs for the backing plate 10 for each hand-held electric cutting tool 3 having a different distance.

In the third embodiment shown in FIGS. 6 and 7, the fixed wood member 12 is attached to the backing plate 10 with the bolt 21 and the nut 20.

That is, the screw shaft of the bolt 21 is penetrated through the contact plate 10, and the long hole 22 perpendicular to the guide surface 11 is provided in the wooden member 12, and the screw shaft of the bolt 21 is inserted into the long hole 22. The bolt shaft 21 inserted through the slot 22 is fixed by tightening the screw shaft of the bolt 21 with the nut 20, and the fixed wood member 12 is fixed along the slot 22 to one side 13 of the backing plate 10. It can be moved in parallel with.

With this tool, the distance between the joist member 12 and the one side 13 can be adjusted, so that various hand-held electric cutting tools 3 having different distances between the cutting blade 5 and the base end surface 6 can be used.

In addition, for example, when the one side 13 is scraped by the deflection of the cutting blade 5 or the like and the distance from the guide surface 11 of the fixed tree to the one side 13 of the backing plate 10 becomes short, the fixed tree member 12 is moved, and its length is adjusted to be equal to the distance from the cutting blade 5 of the hand-held electric cutting tool 3 to the base end face 6, and the cutting line 14 and one side 13 of the backing plate 10 are constantly adjusted. Can be matched.

FIG. 8 shows, as a fourth embodiment, for example, a fixed tree 2 described in the conventional example of FIG. 9 provided with a backing plate 10.

[0030]

【effect】

 Since the present invention is configured as described above, the fixed tree can be easily positioned on the material to be cut by simply arranging one side of the backing plate along the cutting line of the material to be cut, which is convenient.

In addition, at the time of cutting, the edge of the cutting line is pressed by the patch plate, and the hand-held electric cutting tool moves on the patch plate to perform the cutting, so that no whiskers or whiskers are generated at the cut end. Moreover, the surface of the material to be cut is not damaged. Therefore, the cut end and the surface of the cut material after cutting can be finished cleanly.

On the other hand, in the case where the backing plate is formed by a cuttable member, the backing plate can be cut only by the electric cutting tool, and for example, the backing plate adapted to a hand-held electric cutting tool with a different distance between the cutting blade and the base end Since the plate can be formed, it is not necessary to prepare a large number of standard woods having different sizes of the patch plate in accordance with the hand-held electric cutting tools having different distances.

Further, in the case where the fixed wood member is provided so as to be movable in parallel with one side of the backing plate, the distance between the two can be adjusted according to the distance between the base end face and the cutting blade of a different hand-held electric cutting tool. Therefore, it can be used for electric cutting tools having different distances without cutting the above-mentioned pad. Also, with this tool, if one side of the backing plate is shaved during cutting and the distance between the fixed wood member and one side of the backing plate becomes short, hold the distance between them by hand. Since it can be adjusted to be equal to the distance of, the one side of the backing plate can always be aligned with the cutting line of the material to be cut.
