description The utility model discloses a locking operation mechanism of an isolating switch, comprising a bracket. The bracket is rotatably provided with a main shaft which is fixedly provided with an auxiliary shaft in parallel; the main shaft is fixedly provided with three cams which are provided with poking strips; three crank arms are sheathed on the auxiliary shaft at the positions corresponding to the three cams, and are respectively connected with corresponding operation ends; and the crank arms are provided with chutes matched with the corresponding poking strips. In the locking operation mechanism, operations of power transmission and power failure are controlled only by rotation of the main shaft, operation sequence dose not need to be memorized, the structure is simple and reasonable, the error prevention performance is good and the operation is safe and reliable.
