The invention relates to a hoisting device for operation on an external line electrician pole. The hoisting device comprises a chain link type self-locking clamp and a rope self-locking type pulley; the chain link type self-locking clamp is used for being circumferentially buckled and clamped on a telegraph pole and comprises a plurality of arc-shaped chain links, the plurality of arc-shaped chain links are hinged pairwise to form a chain link string, the two ends of the chain link string are connected through a self-locking structure, and the self-locking structure can be opened in the circumferential direction and locked in the circumferential direction; the rope self-locking type pulley is used for hoisting and transporting a heavy object and comprises a main plate, a hoisting hook capable of being hung on the chain link type self-locking clamp is arranged at the top of the main plate, a pulley is hinged to the main plate, a rope is wound on the pulley, a rope clamping structure is arranged in the position, located below the pulley, of the main plate, one end of the rope penetrates through the rope clamping structure to hang the heavy object, and the rope clamping structure can clamp and lock the rope. Through cooperation of the chain link type self-locking clamp and the rope self-locking type pulley, the hoisting device is fixedly hung on the telegraph pole to cooperate with an external line electrician to conduct construction operation on the pole, the heavy object hoisting and transporting process is safe and reliable, manpower occupation is reduced, and the purposes of safety and labor saving are achieved.
