The invention relates to the technical field of optical fibers, and discloses a high-efficiency and safe peeling device for waste gas optical fiber recovery. The device comprises a housing, and the interior of the housing is fixedly connected with a placing table; through the combined action of a placing table, a sleeve block, a plug, a socket, a rotating rod, a push rod, an ejector rod and a clamp, an optical fiber is automatically clamped and fixed, the peeling operation is facilitated, the subsequent peeling operation is triggered by utilizing the operation condition of the fixing operation, the linkage between structures is increased, the operation is convenient, the automation degree is relatively high, the automatic cutting knife cuts into the insulating layer of the optical fiber and extrudes and fixes the cutting surface of the optical fiber, the cutting stability is improved, after the cutting knife is inserted, the insulating layer is linearly moved and cut, human intervention is reduced, the operation safety is higher, and compared with a traditional peeling method, the situation that fibers in the optical fiber are damaged is effectively avoided. The working efficiency is higher, and the use requirements are met.
