The utility model discloses a support for peeling an outer insulating layer of an insulating lead in pole and tower operation. The support comprises a U-shaped bayonet, two angle-steel supports are arranged on the U-shaped bayonet, the upper ends of the two angle-steel supports are respectively provided with arched shoe plates, and fastening screws are arranged under the U-shaped bayonet. During construction, the U-shaped bayonet is fixed at the position of an iron crossbeam of a tower, the support is firmly fixed to the iron crossbeam via the screws, the insulating lead is placed on the arched shoe plates at the upper end of the support, and thus, the insulating layer can be peeled via a wire stripper. Difficulties in construction caused by that the insulating lead is large in diameter, heavy and difficult to peel are thoroughly overcome, the support is simple in operation and convenient to carry, the construction quality is ensured, and the technical problems of being time and labor consuming, low in construction efficiency and difficult to peel the insulating layer in the prior art are solved.
