The working principle of the invention is explained in detail as follows:

(1) closing-isolating

When the three stations are located at the isolation position, the starting motor 111 drives the motor driving shaft 113 to rotate, the motor driving shaft 113 drives the input gear 112 to rotate, the closing half-page gear 115 is meshed with the input gear 112 to be driven to rotate, so that the closing transmission pin 117 located on the closing half-page gear 115 integrally rotates relative to the central axis of the closing half-page gear 115, the closing transmission pin 117 drives the closing transmission piece 119 welded on the closing input shaft 121 to rotate, and the closing input shaft 121 is driven by the closing driving module 11.

The switching-on input connecting pin 124 is connected to the elastic module 14 and interacts with the elastic module 14 to compress the elastic module 14, and after the elastic module 14 reaches a dead point position due to the incomplete gear arrangement of the switching-on half-page gear 115, the elastic module 14 releases energy to push the outer switching-on input plate 122 and the inner switching-on input plate 123, so that the switching-on toggle plate 126 rotates, then the switching-on toggle plate 126 pushes the switching-on toggle pin 153 to move, the output rotary block 152 is driven to rotate from an isolation position to a switching-on position, and the output shaft 154 is driven by the output rotary block 152 to output a switching-on action.

When the isolation action needs to be output, the closing input shaft 121 can be electrically controlled by a manual or closing driving module to rotate in the opposite direction, and then the operation process can be opposite to the output closing action, so that the detailed description is omitted.

(2) Ground-isolation

The grounding input module 13 is basically the same as the switching-on input module 12 in arrangement, but considering the space structure problem, the electric drive module is not added.

When the three stations are in the isolation position, the grounding input shaft 131 is manually controlled to rotate, the external grounding input plate 132 and the internal grounding input plate 133 rotate along with the grounding input shaft 131, and the grounding dial plate 136 is driven by the grounding input shaft 131 to rotate.

The grounding input connecting pin extension 134 is connected to the elastic module 14 and interacts with the elastic module 14 to compress the elastic module 14, after the elastic module 14 reaches the dead point, the elastic module 14 releases energy to push the external grounding input board 132 and the internal grounding input board 133, so that the external grounding input board 132 and the internal grounding input board 133 drive the grounding shifting plate 136 to rotate, then the grounding shifting plate 136 pushes the grounding shifting pin 151 to move, the output rotary block 152 is driven to rotate from the isolation position to the grounding position, and the output shaft 154 is driven by the output rotary block 152 to output the grounding action.

When the output isolation action is required, the grounding input shaft is manually controlled to rotate in the opposite direction, and then the operation process can be opposite to the output grounding action, so the description is omitted.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
