An auxiliary labor-saving tool for manufacturing a 110kV cable head relates to the technical field of auxiliary tools for manufacturing power equipment, is of an integrated structure, and comprises awide part, a narrow part, a clamping groove, a power generation handle and a file part. The beneficial effects of the utility model are that: the utility model discloses: have: the beneficial effect is: According to the thickness of the corrugated aluminum sheath of the cable and the distance between the corrugated aluminum sheath and the shielding layer on the inner side, the auxiliary labor-saving tool matched with the cable head in size is designed, the problem that the wave trough of the corrugated aluminum sheath damages main insulation in the manufacturing process of the cable head is solved, and therefore it is guaranteed that the corrugated aluminum sheath bears electric field balance; the uneven part of the tip end of the corrugated aluminum sheath after fracture lead expansion inthe manufacturing process of the cable head can be polished to be smooth, so that the working efficiency of the manufacturing process of the cable head and the safety and reliability of the cable head are improved; the working efficiency is improved, the working time is saved, and the damage to the main insulation of the cable is avoided.
