BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the present invention (how to carry out the invention) will be briefly described with reference to the drawings showing its function and effect.

When the material 7 to be cut is sandwiched and cut by the cutting blade plate portion 2 of the one holding half body 1a and the slit blade portion 4 of the other holding half body 1b, the cutting blade plate portion 2 becomes the slit blade portion 4 of the slit blade portion 4. A strip-shaped cutting piece 7a is cut and dropped by being fitted and inserted into the insertion gap 3 and by the blade edge 2a of the cutting blade plate portion 2, the blade edge 4a of the slit blade portion 4 and the blade edge 6a of the erection blade portion 6. Becomes

Therefore, since the material to be cut 7 is cut with a width along the width of the insertion gap 3 of the slit blade portion 4, it is very easy to cut, and the cut pieces 7a are cut into the material 7 to be cut. Since it does not remain in the way of cutting and does not interfere with cutting, even when cutting a material 7 having a corner, such as a channel-shaped field edge receiving connector or a light ceiling bar, the cutting should be performed once at the corner. It is possible to continue cutting without stopping and reinserting the blade part of the holding cutting tool.

Further, according to the second aspect of the present invention, when the material 7 to be cut is cut, the blade edge 4a on one side of the slit blade portion 4 slightly escapes to the outside, and the cutting blade plate portion. Since the blade edge 2a of No. 2 and the blade edge 4a of the slit blade portion 4 are cut at a good distance, burrs and warps are less likely to occur at the cutting edge, and the channel-shaped edge as described above is formed. It is even more suitable for cutting thin plates such as field connection connectors and light ceiling bars.

Embodiments of the present invention will be described with reference to the drawings.

In the holding and cutting tool B of this embodiment, a pair of holding halves 1a and 1b having a gripping portion on the base end side are pivotally mounted near the tips so that the tips can be opened and closed.

More specifically, one holding half 1a is
The cutting blade plate portion 2 is formed of a plate material having a predetermined shape, and has a blade edge 2a at the left and right edges at the tip.

The other holding half 1b is one holding half 1b.
a sandwiching half half 1b composed of two plate members of a predetermined shape forming a pair with a, and one sandwiching half half 1a formed of the two plate members.
The pair of gripping halves 1a
1b is configured to be pivotally attached near the tip.

As a result, a slit-shaped insertion gap 3 into which one cutting blade plate 2 can be fitted and inserted is formed at the tip of the other holding half 1a made of two plates. A blade edge 4a is formed on the facing inner edge of the gap 3 and a slit blade portion 4 is formed on the tip of the other holding half 1b.

That is, when the gripping portion of the gripping and cutting tool B is gripped,
The cutting blade plate portion 2 of one holding half body 1a is the other holding half body 1a.
It is configured to be fitted and inserted into the insertion gap 3 of the slit blade portion 4 of b.

Further, a erection portion 5 is provided in a erected state at the tip of the insertion gap 3 of the slit blade portion 4, and a blade edge 6a is formed on the inner edge of the erection portion 5 to form the erection blade portion 6. .

Therefore, as shown in FIG. 2, when the channel-shaped material to be cut 7 is cut by the holding and cutting tool B, the insertion gap is made by the blade edge 2a of the cutting blade plate portion 2 and the blade edge 4a of the slit blade portion 4. Since the material 7 to be cut is cut with a width along the line 3, the cutting piece 7a is cut from the material 7 to be cut into a strip shape by the blade edge 6a of the erection blade portion 6 and drops. The piece 7a does not hinder continuous cutting, and the channel-shaped material 7 can be easily cut along the arrow in the drawing.

Further, the present embodiment is constructed as a cantilever erection structure in which the erection end portion on one side of the erection portion 5 and the tip end portion on one side of the slit blade portion 4 are divided to hold a small gap 8. When the cutting blade plate portion 2 of the one holding half body 1a is fitted and inserted into the insertion gap 3 of the slit blade portion 4 of the other holding half body 1b, one edge of the slit blade portion 4 is slightly Escape to the cutting blade plate 2
The blade edge 2a and the blade edge 4a of the slit blade portion 4 are cut in a state in which a good distance is maintained, so that the cutting edge of the material 7 to be cut is less likely to cause burrs or warp.

Further, in this embodiment, as shown in FIG. 7, the blade edges 4a on both sides of the slit blade portion 4 are constituted so that the intermediate portion is a curved blade edge 4a 'which curves outward. Thereby, when the cutting blade plate portion 2 is fitted and inserted into the insertion gap 3 of the slit blade portion 4, there is a little gap between the blade edge 2a in the middle of the cutting blade plate 2 and the blade edge 4a in the middle of the slit blade portion 4. Since it is generated, the blade edge 2a easily enters the blade edge 4a, and the tip portion of the blade edge 2a is fitted into the blade edge 4a that is narrowed toward the tip side, so that the erected portion 5 is formed as described above. In combination with the fact that the erected end on one side and the tip on one side of the slit blade 4 are separated, the blade edges 4a on both sides are slightly bent outwards to create the best cutting state. The cutting action is further improved.

[0021]

Since the present invention is configured as described above, the material to be cut is held by the cutting blade plate portion of one holding half body and the slit blade portion of the other holding half body, and this cutting blade plate portion is held. Is inserted into the insertion gap of the slit blade and inserted and sandwiched,
A strip-shaped cut piece is cut out and dropped from the material to be cut by the blade edge of the cutting blade plate portion, the blade edge of the slit blade portion, and the blade edge of the erected blade portion.

Therefore, since the material to be cut is cut with a width along the insertion gap width of the slit blade portion, it is very easy to cut, and the cut pieces remain on the material to be cut and interfere with the cutting. Therefore, even when cutting a material having a corner such as a channel-shaped field edge receiving connection tool or a light ceiling bar, the cutting is temporarily stopped at the corner and the holding cutting tool is used. It is a highly practical holding and cutting tool that can continue cutting without re-inserting the blade.

According to the second aspect of the invention, the cutting blade plate portion of one holding half body and the slit blade portion of the other holding half body hold the material to be cut, and the cutting blade plate portion is held. When the insert is inserted into the slit blade insertion gap and sandwiched and cut, the blade edge on one side of the slit blade part slightly escapes outward, and the blade edge of the cutting blade plate part and the slit blade part Since cutting will be performed with a good distance from the blade edge, burrs and warpage will not easily occur at the cutting edge of the material to be cut, and the above-mentioned channel-shaped field edge receiving connection tool and light ceiling bar etc. It is a most suitable holding and cutting tool for cutting thin plates.
