s3, pushing the breaker mechanism along the groove track of the L-shaped lifting arm, inserting the anti-falling baffle, hanging the hook and fixing the breaker mechanism;
s4, stepping on a pressure pedal, converting the pressure energy of the liquid into driving mechanical energy by means of a series of mechanical devices, and drawing the L-shaped lifting arm to move upwards;
and S5, adjusting the control knob, releasing pressure, enabling the lifting arm to move downwards, and enabling the control knob to start and stop at any time by stepless speed regulation, so that the ground clearance of the circuit breaker mechanism is accurately controlled.
