Many industries and departments have very high requirements on the reliability of power supply, and in order to ensure the continuity of power supply, many important occasions adopt a dual-power automatic transfer switch to supply power for an electric appliance. As a necessary device for switching electric energy, the requirements on the technical performance of the device are also higher and higher. The switching speed of the operating mechanism of the existing dual-power automatic transfer switch is low, the rapid switching-off or switching-on of the dual-power automatic transfer switch cannot be realized, the breaking capacity is low, and the service life of a product is short. In addition, when the main shaft is positioned at the main power supply closing position and the standby power supply closing position, the main shaft is not provided with a limiting structure, other mechanisms outside the operating mechanism cannot be prevented from driving the main shaft to turn over, or the transmission of the existing operating mechanism or the structural design for limiting and unlocking the main shaft is complex, and the switching reliability of two paths of power supplies is low. Disclosure of utility model The utility model aims to overcome at least one defect in the prior art and provide an operating mechanism of a change-over switch.

Optionally, the turntable can rotate to at least three turntable positions, wherein the at least three turntable positions comprise a turntable first position, a turntable middle position and a turntable second position, and the turntable positions correspond to the main shaft to be driven to rotate to three main shaft positions, namely a main power supply switching-on position, a double-split position and a standby power supply switching-on position; When the turntable rotates from the turntable middle position to the turntable first position, or from the turntable first position to the turntable middle position, or from the turntable middle position to the turntable second position, or from the turntable second position to the turntable middle position, the rotation of the turntable firstly drives the energy storage mechanism to store energy and then drives the locking piece to release the locking of the main shaft, so that the energy storage mechanism releases energy to drive the main shaft to rotate to the corresponding main power supply closing position or the corresponding double-split position or the corresponding standby power supply closing position or the corresponding double-split position due to the locking constraint of the locking piece on the main shaft. Optionally, when the turntable rotates from the middle position of the turntable to the first position of the turntable, the locking piece is driven to unlock the main shaft when the first position of the turntable is reached, so that the energy storage mechanism releases energy to drive the main shaft to rotate to a main power supply closing position; And/or when the turntable rotates f
