A closing transmission mechanism, an operating mechanism using the transmission mechanism, and a circuit breaker. The closing transmission mechanism comprises a push rod and a force-transmitting block used for being fixedly arranged together with a corresponding movable contact (4), the force-transmitting block being located below the push rod and a force-bearing shoulder facing the push rod being arranged on the force-transmitting block, a downwardly opening recess used for being in a push fit with the force-bearing shoulder of the force-transmitting block so as to push the force-transmitting block to drive the movable contact (4) towards a stationary contact (5) and close when the push rod moves to the left being arranged on the push rod, a right end of the push rod being provided with a hinge structure. When tripping of the closing transmission mechanism is required, since the recess is in the push fit with the force-bearing shoulder of the force-transmitting block, an upward force is simply applied to the push rod to turn the push rod upward to separate the recess from the force-bearing shoulder of the force-transmitting block. Tripping is convenient, the recess is arranged directly on the push rod, the force-bearing shoulder is arranged on the force-transmitting block, the structure is simple, and disassembly and maintenance are convenient.
