The invention relates to an electric-operation mechanism capable of avoiding the malfunction. The electric-operation mechanism capable of avoiding the malfunction comprises an electromotor, wherein the electromotor drives a cam to rotate by a gear pair; the cam is arranged on a mounting plate; the cam is provided with a locating shaft; and the locating shaft drives a sliding block in a sliding block mechanism to vertically move. The electric-operation mechanism is characterized in that the mounting plate is provided with a groove; a stop end of a stop assembly extends into the groove and can freely move in the groove; the stop end is used for abutting against the edge of the cam to prevent the cam from moving after a circuit breaker is switched on; the other end of the stop assembly is connected to the mounting plate by a restoring mechanism; the restoring force of the restoring mechanism is far smaller than operation force acted on the cam; and when a locating shaft moves to a switching-off area from a switc
