The invention relates to a circuit breaker transmission structure and circuit breaker equipment using the structure. The circuit breaker transmission structure comprises symmetrically arranged first and second arc-extinguishing chambers, first and second arc-extinguishing chamber crank arms which are connected with the moving contact rods of the first and second arc-extinguishing chambers in a transmission way, an insulating pull rod which is hinged with each arc-extinguishing chamber crank arm and a pull rod driving crank arm which is used for driving action of the insulating pull rod. The insulating pull rod comprises first and second insulating pull rods which are hinged with the first and second arc-extinguishing chamber crank arms. Each insulating pull rod is hinged with the pull roddriving crank arm. The pull rod driving crank arm, the first insulating pull rod and the first arc-extinguishing chamber crank arm form a parallelogram mechanism. The pull rod driving crank arm, the second insulating pull rod and the second arc-extinguishing chamber crank arm form a contra-parallelogram mechanism. According to the scheme, the problems of high number of transmission links and complex structure of the present circuit breaker transmission structure can be solved.
