The linkage pushing connecting rod 14 is rotatably connected to the connecting rod fixing piece 12, the middle of the linkage pushing connecting rod 14 is hinged to the shell 1, the end, far away from the connecting rod fixing piece 12, of the linkage pushing connecting rod 14 is located at the lower end of the linkage pushing block 15, when the electromagnetic driving mechanism 6 receives a disconnection command signal, the electromagnetic driving rod 601 descends to drive the connecting rod fixing piece 12 to descend, the end, located at the lower end of the linkage pushing block 15, of the linkage pushing connecting rod 14 is lifted upwards to push the linkage pushing block 15 to be switched from the first position to the second position.

Therefore, in the present embodiment, when the electromagnetic driving mechanism 6 receives the opening command signal, the tripping link 13 and the linkage pushing link 14 are synchronously driven, the energy storage locking block 10 is switched from the locking position to the unlocking position, and the linkage pushing block 15 is switched from the first position to the second position simultaneously (the time difference between the two is within a very small error range), the end of the energy storage arm leaves the energy storage locking slot 1001 to unlock the energy storage arm by the energy storage locking block 10, the tripping protrusion 206 is lifted upwards to enable the operation rotation base 5 to be free, and the linkage pushing block 15 pushes the elastic plate 505 to approach to the axial direction to enable the linkage protrusion 304 to be inserted into the linkage groove 506 simultaneously (the time difference between the three is within a very small error range), so that during the process that the second energy storage element 7 releases the energy to drive the first operation rotation shaft 3 to move from the closed state to the open state, the clamp spring assembly 2 does not form resistance on the operation rotating seat 5, the operation rotating seat 5 and the first operation rotating shaft 3 form linkage relation, in the turning-off process of the rotary switch, the first energy storage element 4 is always in an energy release state or is basically close to the energy release state, resistance action is basically not formed on the operation rotating seat 5 and the first operation rotating shaft 3, and external force for driving the operation mechanism is only elastic force of the second energy storage element 7.

If the energy storage locking block 10 is pushed to be switched from the locking position to the unlocking position, the energy storage locking block 10 does not push the second steering limiting elastic block 202, that is, the operation rotary seat 5 is still in the locked state, the elastic force of the second energy storage element 7 in the energy storage state needs to be larger than that of the first energy storage element 4 after energy storage is completed, so that the second energy storage element 7 can drive the first operation rotating shaft 3 to move to the position of the disconnected state while the first energy storage element 4 completes energy storage, and then the operation rotary seat 5 moves to the position of the disconnected state under the energy release effect of the first energy storage element 4, while the elastic force of the second energy storage element 7 in the energy storage state does not need to be larger than that of the first energy storage element 4 after energy storage is completed, and the two are not related.

If do not set up linkage ejector pad 15, rely on first operation pivot 3 alone, first energy storage component 4, operation swivel mount 5 drives in proper order and makes operation swivel mount 5 rotate closed position, operation swivel mount 5 action can take place to postpone, in this embodiment, first operation pivot 3 is driven by second energy storage component 7 and is rotated to the position of off-state in short time, operation swivel mount 5 keeps the circumferential direction linkage relation with first operation pivot 3 in short time, thereby reduce the delay time that operation swivel mount 5 rotated the position of off-state, reach the purpose that cuts off more fast.
