Embodiment Construction
[0021] Examples of drive shafts for circuit breakers are image 3 Shown: It includes a crankshaft body with a main shaft diameter 23, a connecting rod 25 and a connecting rod shaft diameter 26. The main shaft diameter is used for transmission connection with the power output end of the corresponding operating mechanism, and the connecting rod shaft diameter has a flat plate structure , the connecting rod shaft diameter 26 is provided with three shift fork fixing structures at intervals along its axial direction, which are respectively used to fix the corresponding insulating shift forks. The mounting plate is used for the corresponding connecting bolts to pass through to realize the bolt perforation 26-1 for the fixed assembly of the shaft diameter of the connecting rod and the corresponding insulating shift fork.
[0022] In other embodiments of the drive shaft for the circuit breaker: there may be multiple shaft diameters of the connecting rods, and at this time, each ...
