The invention discloses a spring operating mechanism. The number of output shafts in the spring operating mechanism is more than two. Each output shaft is provided with an output crank arm correspondingly in a rotating-stopping mode. A free end of each output crank arm is connected to a sliding groove formed in an output cam (E) correspondingly. Each output crank arm forms a swinging guiding rod mechanism through the corresponding sliding groove and the corresponding output cam (E). Accordingly, more than two output shafts are driven to move through one output cam, each output shaft drives a corresponding isolating switch or breaker equipment to carry out opening-closing movement. Meanwhile, the sliding grooves in the output cams enable the output crank arms assembled on the output shafts in an eccentric-rotating-stopping mode and the output cams to form the swinging rod guiding mechanisms which can guarantee reliable transmitting torque from the output cams to the output crank arms, a reliable transmission effect is achieved through an ingenious connecting rod transmission mechanism, the performance stability of the spring operating mechanism is improved, and the service life of the spring operating mechanism is prolonged.
