In this embodiment, when the operating device is in the normally-used-side closing state: as shown in fig. 23, due to the acting force of the main spring 4 on the common side connecting pin shaft B02 and the spring shaft a03, the flip lever a01 on the common side contacts the flip lever limit protrusion 102, and the upper connecting rod B01 on the common side contacts the limit part 109 arranged on the bracket 1; the first connecting pin shaft B02 abuts against the bottom of a lower connecting rod sliding groove B0501 of the lower connecting rod B05 to limit the lower connecting rod B05 to slide, and at the moment, the included angle between the hinged points of the common side lower connecting rod B05 and the upper connecting rod B01 is larger than 180 degrees to form self-locking. The standby-side upper connecting rod B01 'contacts a limiting part 109' arranged on the bracket 1, and the double-position-division locking shaft C03 is located at an initial position of the via hole 106 on the bracket 1, at this time, as shown in fig. 19, the common-side upper connecting rod B01 overcomes the acting force of the indicator return spring D02 through the upper side wall to link the indicator linkage part D010 so as to drive the indicator D01 to display the power state of common-side switching-on, and the standby-side indicator return spring D02 'provides acting force to the standby-side indicator D01' so as to display the standby-side power switching-off state.
When the operating device is in a switching-on state of a common side and is switched to a double-division position: as shown in fig. 24, the standby side electromagnet 3' is energized, the iron core of the electromagnet 3' is connected with the standby side electromagnet lever a04' to drive the standby side turning lever a01' to rotate counterclockwise, and simultaneously the standby side turning lever a01' drives the common side turning lever a01 to rotate counterclockwise through the connecting plate 2; or when the manual operation is carried out, the operating lever 6 is pulled from the opening K of the shell through the handle M, the operating lever 6 drives the rod connecting plate 2 to move towards the standby side, and the connecting plate 2 simultaneously drives the common side turning lever A01 and the standby side turning lever A01' to rotate anticlockwise. The corresponding main springs 4 and 4 'are rapidly contracted after reaching the maximum position along with the increasing of the rotation deformation of the corresponding common side turnover lever A01 and the spare side turnover lever A01', one ends of the common side turnover lever A01 and the spare side turnover lever A01 'drive the corresponding common side turnover lever A01 and the spare side turnover lever A01' to continue anticlockwise rotate until the spare side turnover lever A01 'contacts with a turnover lever limiting bulge 102' arranged on the bracket 1, the other ends of the common side main springs 4 drive the common side upper connecting rod B01 and the lower connecting rod B05 to upwards turn through a connecting pin shaft B02 until the upper connecting rod B01 contacts with a limiting part 050050050109 arranged on the bracket 1, the connecting pin shaft B02 is separated from the lower connecting rod sliding groove B1 and continues to rotate to a lower connecting rod limiting bulge B2, and meanwhile, the lower connecting rod B05 drives the main shaft B07 to rotate towards a double-division position through a connecting pin shaft three B06. And a first connecting pin shaft B02 'connected with the other end of the standby side main spring 4' slides to the bottom of a lower connecting rod sliding groove B0501 'of the standby side lower connecting rod B05' and then drives the standby side upper connecting rod B01 'and the standby side lower connecting rod B05' to overturn downwards, and meanwhile, the lower connecting rod B05 'drives the main shaft B07 to rotate towards a double-division position through a third connecting pin shaft B06'.
The corresponding connecting pin shafts three B06, B06' simultaneously drive the stop plate C01 to rotate until the double-positioning locking protrusion C0102 on the stop plate C01 is clamped on the double-positioning locking shaft C03, and then the double-positioning locking shaft reaches the double-positioning position. At this time, the standby side connecting pin shaft I B02' continues to be acted by the standby side main spring 4' to prevent the lower connecting rod B05' and the main shaft B07 from rotating towards the common side position, the corresponding indicating pieces D01 and D01' leave the corresponding upper side walls of the upper connecting rods B01 and B01', and the corresponding indicating pieces D01 and D01' are all displayed to be in a double-split position under the action of the corresponding indicating piece return springs D02 and D02' as shown in the attached drawing 20.
When the switch operating device is switched from the common side opening to the double-division position to the standby side: the unlocking electromagnet C02 is electrified to drive the bi-level locking shaft C03 to move downwards from the initial position through the via hole 106 on the bracket 1 until the bi-level locking protrusion C0102 on the stop plate C01 is disengaged. Or the handle M pulls the operating lever 6 from the opening K of the housing, and simultaneously the operating lever 6 drives the unlocking lever C04' to press the unlocking sliding plate C05 downwards, and the bi-component linkage arc-shaped hole C0502 on the unlocking sliding plate C05 presses the through hole 106 of the bi-component locking shaft C03 on the bracket 1 downwards from the initial position until the bi-component locking protrusion C0102 on the stop plate C01 is disengaged.
The standby side connecting pin shaft I B02 'is acted by a standby side main spring 4', and simultaneously drives a standby side upper connecting rod B01 'and a standby side lower connecting rod B05' to downwards overturn until the upper connecting rod B01 'contacts a limiting part 109' arranged on the support 1, at the moment, the switch operating device is in a standby side switching-on position state as shown in the attached drawing 25, and simultaneously as shown in the attached drawing 21, the standby side upper connecting rod B01 'overcomes the acting force of an indicating part return spring D02' to link an indicating part linkage part D010 'through an upper side wall so as to drive an indicating part D01' to display a standby side switching-on power state, and the common side indicating part return spring D02 provides acting force for the common side indicating part D01 to display a common side power switching-off state.
When the switch operating device is in the switching-off state of the common side to the switching-on state of the double-branch position to the common side: when the operating device is in a state from the common side opening to the double-division position, the common side electromagnet 3 is electrified or the operating lever 6 is pulled to the common side to drive the common side turning lever A01 and the standby side turning lever A01 'to rotate clockwise, the corresponding main spring 4,4' continuously increases along with the rotation deformation of the common side turning lever A01 and the standby side turning lever A01', and rapidly contracts after reaching the maximum position, and one end of the corresponding main spring 4,4' drives the spring common side turning lever A01 and the standby side turning lever A01 'to continuously rotate clockwise until the common side turning lever A01 contacts the turning lever limiting protrusion 102' arranged on the bracket 1. The other end of the common side main spring 4 drives the first connecting pin shaft B02 to rotate from the lower connecting rod limiting protrusion B0502' on the lower connecting rod B05 to the lower connecting rod sliding groove B0501 and slide into the lower connecting rod sliding groove B0501 until the first connecting pin shaft B02 reaches the bottom of the lower connecting rod sliding groove B0501, the first connecting pin shaft B02 drives the upper connecting rod B01 and the lower connecting rod B05 to overturn downwards until the upper connecting rod B01 contacts the limiting part 109 arranged on the support 1, and at the moment, the operating device is in a common side closing position state.
