1. A dual energy storage operating mechanism of an isolating switch, comprising:
a housing, a first input shaft and a first output shaft being rotatably disposed in the housing, at least one end of the first output shaft extending out of the housing as an output end linked with the isolating switch, at least one end of the first input shaft extending out of the housing as an operating end;
an input wheel, an output wheel and a limiting mechanism being provided in the housing, the input wheel being coaxial with the first output shaft, the output wheel being coaxial with the first output shaft and linked circumferentially, the limiting mechanism having at least one elastic portion and being locked circumferentially;
the output wheel having a first limiting portion and a linking groove, the limiting mechanism having a second limiting portion and a first pushing portion with a pushing slope;
the input wheel including a linking member partially located in the linking groove and a second pushing portion that cooperates with the first pushing portion, two ends of the linking groove being formed with linking surfaces for mating with the linking member;
the first input shaft driving the input wheel to rotate in at least part of a rotation path of the first input shaft, the second pushing portion interacting with the elastic portion of the limiting mechanism, in a rotation path of the input wheel, the second pushing portion being in contact with the pushing slope so that the limiting mechanism has a first position where the second limiting portion is engaged with the first limiting portion for the output wheel to be locked circumferentially and a second position where the second limiting portion is disengaged from the first limiting portion for the output wheel to be unlocked in a rotatable state;
a first energy storage mechanism being provided between the input wheel and the housing;
a second energy storage mechanism being provided between the input wheel and the output wheel or the first output shaft;
in the rotation path of the first input shaft from a switching-on position to a switching-off position, the first energy storage mechanism having an energy storage state and an energy release state, wherein when the first energy storage mechanism is in the energy storage state, the linking member slides in the linking groove, the limiting mechanism is in the first position, and the second energy storage mechanism is in an energy storage state; when the first energy storage mechanism is in the energy release state, the linking member abuts against the linking surface, the limiting mechanism is in the second position, and the second energy storage mechanism is in an energy release state.
