Cable local heating device

The invention relates to the technical field of cable heating, in particular to a cable local heating device which comprises a body, the interior of the body is hollow to form a cavity, the body is provided with a heating channel, the heating channel penetrates through the body, the side wall of the heating channel is provided with a plurality of air outlet holes, the air outlet holes are communicated with the cavity, the outer wall of the body is provided with air inlet holes, and the air inlet holes are communicated with the cavity. The cable is inserted into the heating channel, hot air entering from the air inlet hole can enter the cavity and then is blown out from the air outlet hole to the cable located in the heating channel, then the body is moved, and the cable is heated to a to-be-stripped position in the length direction of the cable, so that the local position of the cable can be rapidly heated, and the stripping efficiency is improved. And the cable insulation sheath after local heating can be be
