Isolating switch operating mechanism

The utility model relates to a power transmission and distribution switching device, in particular to an isolating switch operating mechanism comprising an operating handle and a disc with an operation hole. A connecting rod is movably connected to the circumference of the disc, a crank arm is movably connected with the other end of the connecting rod, the tail end of the crank arm is movably connected with a movable switch blade of the isolating switch, the diameter of the disc is 140mm, and the center distance of the crank arm is 110mm to 120mm. The operating mechanism has the advantages of simplicity, less components, low cost and easiness in assembly, and can be widely applied to high-source and high-current isolating switches.
