Driving mechanism of disconnecting switch device

A driving mechanism of an isolating switch device comprises a driving rod, a sliding connecting rod and a rotating crank arm. The driving rod is connected to the sliding connecting rod; the sliding connecting rod and the rotary connecting lever are connected together in a buckling manner, so that the sliding connecting rod and the rotary connecting lever are positioned on the same plane; the rotating crank arm is connected with a moving knife main shaft of the disconnecting switch device; when the driving rod moves to a first position, the driving rod drives the rotating crank arm to rotate through the sliding connecting rod, and the rotating crank arm rotates to drive the moving knife main shaft to move, so that the moving knife main shaft moves to drive the disconnecting switch to be in a closed state; and when the driving rod moves to a second position, the driving rod drives the rotating crank arm to rotate through the sliding connecting rod, and the rotating crank arm rotates to drive the moving knife ma
