  The present invention has been made in view of the above points, and the object of the present invention is to easily cut the insulation cable coating in a narrow place inside a switchboard or the like in consideration of workability and safety. An object of the present invention is to provide an insulated cable covering and cutting tool capable of performing the above.

  The feature of the present invention is an insulated cable sheath cutting tool that can cut an insulated cable sheath in a narrow place. In particular, the work for cutting and peeling off the covering portions of the insulated cables often requires one hand to cut the covering at a narrow portion inside the switchboard in which those cables are incorporated. The cutting tool has a cylindrical structure so that the gripping part for rotating the work tool for covering and cutting is not caught by the parts inside the board. In order to allow one-handed operation in the machining operation, the mechanism for switching between the horizontal cutting blade and the vertical cutting blade uses a slide mechanism in a direction perpendicular to the axial direction of the insulated cable so that it can be easily operated with one hand. Further, according to the present invention, the cutting blade, which is a risk factor such as injury to the operator, is structured to be attached inside the cutting tool.

  Since the present invention is configured as described above, it is possible to easily perform the operation of cutting off the insulation coating of the insulated cable to be cut by one hand to rotate and pull out.

  Therefore, even in a narrow internal place such as a switchboard or control panel, it is possible to easily work on a thick cable terminal incorporated in the panel.

  Further, there is no restriction at the work place, which was a drawback in the rotation operation by the nipping and cutting method with the conventional cable cutter or the grooving work with the hook knife, and the efficient cable processing work becomes possible.

  According to the present invention, since the cutting blade has a structure that does not come into direct contact with the operator's hand, it is possible to provide an insulated cable-covered cutting tool that is excellent in terms of worker safety.

  In addition, according to the method of the present invention, it is possible to prevent accidental damage to the cable core wire due to excessive cutting in the thickness direction of the insulation coating, compared to the case of cutting the insulation cable coating with a general cutter knife or the like. Therefore, it is possible to realize an insulated cable coated cutting tool that exhibits a very good cutting function.

  The diameter of the cable holder which is a component of the present invention can be manufactured by a molded product of an insulator having an outer diameter of about 60 mm even when the insulated cable cross section to be worked is 250 square millimeters, and is small and lightweight.
