[0062] Detailed Explanation of the Working Principle of the Present Invention:

[0063] (1) Closing - Isolation

[0064] When the three - position is in the isolation position, start the motor 111 to drive the rotation of the motor drive shaft 113. The motor drive shaft 113 drives the rotation of the input gear 112. The closing half - page gear 115 meshes with the input gear 112 and is driven to rotate, causing the closing transmission pin 117 on the closing half - page gear 115 to rotate as a whole relative to the center axis of the closing half - page gear 115. The closing transmission pin 117 drives the rotation of the closing transmission piece 119 welded on the closing input shaft 121. The above is the driving process of the closing input shaft 121 by the closing drive module 11.

[0065] In addition, the end of the closing input shaft 121 can extend to receive external manual control for rotation. The external closing input plate 122 can rotate following the closing input shaft 121. The closing dial 126 is driven to rotate by the closing input shaft 121. The external closing input plate 122 is provided with a closing input connecting pin 124 for engagement.

[0066] The closing input connecting pin 124 is connected to the elastic module 14 and interacts with the elastic module 14, compressing the elastic module 14. Due to the non - complete gear setting of the closing half - page gear 115, after the elastic module 14 reaches the dead - point position, the elastic module 14 releases energy and pushes the external closing input plate 122 and the internal closing input plate 123, causing the closing dial 126 to rotate. Subsequently, the closing dial 126 pushes the closing dial pin 153 to move, and the output rotating block 152 is driven to rotate from the isolation position to the closing position. The output shaft 154 is driven by the output rotating block 152 to output the closing action.

[0067] When an isolation action needs to be output, the closing input shaft 121 can be manually or electrically controlled by the closing drive module to rotate in the reverse direction. Subsequently, the operation process can be opposite to the output closing action, so it will not be elaborated here.

[0068] (2) Earthing - Isolation

[0069] The earthing input module 13 is basically arranged in the same way as the closing input module 12, but considering the space structure problem, its electric drive module is not added.

[0070] When the three - position is in the isolation position, manually control the rotation of the earthing input shaft 131. The external earthing input plate 132 and the internal earthing input plate 133 rotate following the earthing input shaft 131. The earthing dial 136 is driven to rotate by the earthing input shaft 131.

[0071] The ground input connecting pin 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 center position, the elastic module 14 releases energy to push the outer ground input plate 132 and the inner ground input plate 133, so that the outer ground input plate 132 and the inner ground input plate 133 drive the ground dial plate 136 to rotate. Subsequently, the ground dial plate 136 pushes the ground pin 151 to move, and the output rotating block 152 is driven to rotate from the isolation position to the ground position, and the output shaft 154 is driven by the output rotating block 152 to output the grounding action.

[0072] When the isolation action needs to be output, the ground input shaft is manually controlled to rotate in the reverse direction, and then the operation process can be opposite to the output grounding action, so it will not be elaborated here.

[0073] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
