Abstract

PURPOSE: To operate the tool in simple form even if the cable clad is too hard or thick by using a longitudinal hole as a guide part for the cable to be peeled while the cable is carried to a cutting knife. CONSTITUTION: This tool consists of the longitudinal hole 7 which is arranged inside so as to guide the cable 8 and casings 1 and 2 having a couple of lever drive parts which can be operated by hand; and the drive parts are supported by levers 28 and 29 facing the longitudinal hole 7 in the casings and cutting knives 9 and 10 which rush in the longitudinal hole 7 are arranged atop of the drive parts while being viewed in the conveyance direction of the cable 8. Consequently, this can be used even for, for example, a thick synthetic material clad and a laminated insulating layer consisting of various materials, and only the force for using the hand tool is needed.

No. 2, discloses a cutting tool which can be actuated by hand via a lever drive in the area of the knife and has at least one gearwheel which engages with the cable sheathing in order to generate the feed movement. By means of one or more gear wheels connected directly to the cable sheathing, the transmission of the force for the forward movement of the knife takes place in the immediate vicinity of the slitting knife in the direction of the sheathing surface and thus into the cable axis. The gear wheel or gears can be activated in a simple manner by means of a lever drive and, if necessary, by a speed-up transmission.

を実現することは不可能とみなされている。However, a disadvantage of hand-actuated tools is that they generally cannot be used for anything other than stripping thin cable jackets. The cable jacket is either too hard or too thick. In both cases, it is considered impossible for hand tools with a lever drive or a lever drive with transmission to achieve satisfactory cutting or cutting guidance without causing damage to the internal parts of the cable. has been done.
