Between frame right side wall.Also include leading screw and handwheel, the right side wall of the leading screw and U-shaped knife rest is connected through a screw thread, leading screw left end
It is flexibly connected with right support, leading screw right-hand member is connected with handwheel.Also include handle, the handle is arranged on the bottom of U-shaped knife rest.
It is using beneficial effect caused by above-mentioned technical proposal：C-shaped knife of the invention by electrothermal steel cutter
Disk is heated to more than 500 degree, cuts off the electricity supply and extracts latch, can carry out thermal cutting to the rubber or plastic peel of cable, can prevent
The plain conductor inside cable is hurt, suitable for more specification cables.The present invention is simple in construction, and use is efficient and convenient, saving of work and time,
Labor intensity can be reduced, improves cable construction efficiency.

Embodiment
Embodiment 1：A kind of thermal cutting cutter of cable sheath, including electrothermal steel cutter and its heating power supply are inserted
Head, U-shaped knife rest 1 and support wheel 11；The electrothermal steel cutter are the internal C-shaped cutterhead 4 for being provided with insulating sleeve 17, described
The periphery of insulating sleeve 17 is provided with the insulation board 8 of disjunctor, and insulating sleeve 17 is inlaid in C-shaped cutterhead 4, the C in the both sides of insulation board 8
Pin hole 7 is respectively equipped with shape cutterhead 4, the pin hole 7 is adapted with heating power supply plug；The electrothermal steel cutter
It is arranged on by the left socle 6 equipped with rotating shaft in the inner left wall of U-shaped knife rest 1, the support wheel 11 passes through the right side equipped with rotating shaft
Support 14 is arranged on the right side inwall of U-shaped knife rest 1, and the center of C-shaped cutterhead 4 is with the center of support wheel 11 in same horizontal line
