(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a cutter.

[Conventional technology and problems]

In cable work such as electrical wiring, bare wires are covered with insulating (vinyl) tape, but the tape was conventionally cut by tearing it off by hand or using an edged tool such as a knife. However, since the insulating tape has ductility, it does not cut well even if it is torn by hand. Alternatively, when cutting with a knife, there are problems such as having to search for the knife.

SUMMARY OF THE INVENTION An object of the present invention is to solve these conventional problems and to provide a cutter that can be conveniently carried around, fit into a finger, and has good workability.

[Means for solving problems]

In the cutter according to the present invention, a holding body provided with a cutting object is sunk into the outer periphery of a finger ring into which a person's finger is inserted.

[Effect]

When the cutter configured as described above is fitted onto a finger, the insulating tape, etc. is easily pressed against the blade of the cutter after wrapping the insulating tape, etc. around an electric wire, cable, etc., and the insulating tape, etc. is immediately cut. Ru.

〔Example〕

Hereinafter, the present invention will be explained in detail based on drawings showing examples.

゛In Fig. 1, 1 is a cutter, which is provided with a finger ring 3 made of plastic or the like, and an elastically deformable U-shaped holder 2 made of plastic or the like is integrated in a tangential direction on the circumference of the finger ring 3. It is formed into a shape.

Therefore, a groove 6 having a small U-shaped cross section in the longitudinal direction is provided on the lower surface 5 inside the holder 2, and a groove 6 is provided on the upper surface 7 inside the holder 2 at a position corresponding to the groove 6. A slit portion 8 is provided.

No. 3 Then, a strip-shaped blade object 4 having a blade portion 9 formed on one edge in the longitudinal direction is sandwiched in the slit portion 8 so as to face the groove portion 6 .

The cutter 1 thus formed is fitted onto the middle finger or index finger, and as shown in FIG. The insulating tape 11 is sandwiched between the holders 2 and 2, and the insulating tape 11 is cut by pressing the holder 2 from above in the direction of arrow Y with another finger (not shown).

Further, FIGS. 4A and 4B show another embodiment, which is a scissor-type knife in which a cutter body 4 having a cutter portion 9 is also attached to the lower surface 5 inside the holder 2.

That is, as in FIG. 1, an elastically deformable U-shaped holder 2 is provided that protrudes from the circumference of the finger ring 3, and a slit portion 8 similar to the previous example is provided, and the holder 2 is A slit portion 8 is also provided on the second surface 7 inside the body 2 at approximately the same position corresponding to the slit portion 8. Then, two blade bodies 4 similar to the previous example are provided, and the blade parts 9 of the blade bodies 4, 4,
The insulating tape 11, which is sandwiched between the slits 8.8 and 9 facing each other, is held between the holder 2 and the holder 2 with another finger or the like, as in the previous example. Cut by pressure from the blade.

FIGS. 5A and 5B show still another embodiment, in which V
A cutter body 4 having a letter-shaped blade portion 9 is attached inside the letter-11-shaped holder 2, and the cutter body 4 is of a pull-cutting type in which the insulating tape 11 is cut. Zunawaji, a blade object 4 in which a U-shaped slit portion 8 is attached to the holding body 2, the outer periphery is formed in a U-shape, and a V-shaped blade portion 9 is formed on the inner surface.
is sandwiched between the slits I and 8.

The cutter 1 thus formed cuts the insulating tape 11 by being pushed in the direction of the arrow X.

It is also preferable to provide the U-shaped holder 2 in the normal direction of the finger ring 3. As shown in FIG. By being held between the deformable U-shaped holding body 2 and being pressed with the thumb 5, the insulation tee NO05-111 is cut (see FIG. 2B). Although not shown, the insulating tape 11 can be cut by inserting the middle finger into the roll of the insulating tape 11 and pressing the cutter 1 fitted on the index finger with the thumb 5.

FIG. 7 shows another embodiment in which a holder 2 is rotatably mounted on the circumference of a finger ring 3. That is,
Taking the holder 2 of FIG. 1 as an example, the groove 6 of the holder 2 and the inner peripheral surface of the finger ring 3 are pivotally connected via a small-diameter shaft 13, as shown in FIG.

If the cutter is configured in this way, the holder 2 will be moved in the direction of the arrow M.
It can be freely rotated in the , N direction, and the insulating tape etc. can be torn off at any rotation angle.

It goes without saying that the scissor type or puller type cutter 1 can also be rotatably mounted.

Furthermore, in the following embodiments, the finger ring 3 and the holder 2 may be made of metal as long as they are elastically deformable.

Furthermore, the application of the present invention is not limited to cutting insulating tape, but also cutting cords for packing, wrapping cords for products, cutting thin electric wires and threads, etc. It is also preferable to use it for various force and throat work such as LJ.

〔Effect of the invention〕

Since you can insert your finger into it, it won't be bulky, won't get in the way, and won't get lost or have to be searched for when working.

Further, after wrapping the tape or the like around the electric wire or the like, it can be easily cut, which improves work efficiency. Furthermore, it is compact, has a simple structure, and is inexpensive. Furthermore, by providing the blade body 4 inside the holder 2, the blade body 4 is not exposed to the outside.
Safety Measures] 2 can also be easily made into a preferable cutter 1. In addition, by making the holder 2 an elastic body, by pressing the holder 2 with a finger, the blade 4 can reliably and quickly cut the tape or the like.
