Cable fixing structure of cable reaction force cone cutting device

The utility model relates to a cable fixing structure of a cable reaction cone cutting device in the technical field of high-voltage cable manufacturing, which comprises a device shell, a cable fixing mechanism is fixedly mounted at one end in the device shell, and the cable fixing mechanism comprises a cable restraining sleeve detachably nested in the end face of the device shell. A cutter feeding mechanism is arranged at the other end in the device shell, the cutter feeding mechanism is rotationally installed on the inner wall of the device shell through a bearing, an electric driving mechanism is installed on the outer side of the device shell, and the electric driving mechanism is in transmission connection with the cutter feeding mechanism through a transmission mechanism; and the cable restraining sleeve is formed by sequentially nesting a plurality of sleeve units with different sizes, so that the novel cable reaction force cone cutting device applied by the device can be suitable for cutting and proce
