The terms "first direction", "second direction", "third direction", "fourth direction", and the like herein are described with respect to the drawings of the present invention, unless otherwise specified. The term "sequentially comprising A, B, C, etc" merely indicates the order of the included elements A, B, C, etc. and does not exclude the possibility of including other elements between a and B and/or between B and C.

The drawings in the present specification are schematic views to assist in explaining the concept of the present invention, and schematically show the shapes of respective portions and their mutual relationships.
Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to fig. 1 to 8.
Referring initially to FIG. 1, a manually operated mechanism according to the present invention is shown with its handle in a first position corresponding to a double-split position of a dual power transfer switch, which is now in the double-split position.
The manual operating mechanism includes a handle 1 that is manually rotatable between first, second, and third positions corresponding to the double-split position, the first power position, and the second power position of the dual power transfer switch. The handle gear 2 is pivotally mounted on the frame and is fixedly connected to the handle 1 such that the handle gear 2 can rotate with the handle 1. The first and second energy storing gears 3 and 4 are pivotally mounted on the frame and can mesh with the first or second energy storing gear during rotation of the handle gear 2, thereby rotating the first or second energy storing gear. The first driving gear 5 and the first energy storage gear 3 are coaxially and pivotally arranged on the machine frame, and the second driving gear 6 and the second energy storage gear 4 are coaxially and pivotally arranged on the machine frame. A first elastic element 7 is arranged between the first energy storage gear 3 and the first drive gear 5, and a second elastic element 8 is arranged between the second energy storage gear 4 and the second drive gear 6. As described in further detail below, the first drive gear 5 and the second drive gear 6 are rotated via elastic forces of the first elastic element 7 and the second elastic element 8, respectively, to thereby mesh with the center wheel 9. The center wheel 9 can be connected with a main shaft of the dual-power transfer switch, so that the rotation of the center wheel drives the main shaft to rotate, and then a moving contact of the dual-power transfer switch is switched among a double-division position, a first power switch-on position and a second power switch-on position.
Next, a process of switching the handle of the handle operating mechanism from the first position to the second position, resulting in switching the dual power source changeover switch from the double split position to the first power source on position, will be described with reference to fig. 2 to 4.
When the handle 1 is rotated counterclockwise, the handle gear 2 is also rotated counterclockwise. The handle gear rotates along the anticlockwise direction and can be meshed with the first energy storage gear 3, so that the first energy storage gear rotates along the clockwise direction, and the first elastic element 7 with one end installed on the first energy storage gear deforms to store energy. At this time, the first driving gear 5 is held stationary by a first stopper installed on the frame, which prevents the first driving gear from rotating in the clockwise direction by the first elastic member 7. After the first elastic member 7 passes the "dead point" position, as shown in fig. 3, the first driving gear 5 is rotated in the counterclockwise direction by the elastic force of the first elastic member 7. The "dead point" position is the position: the elastic force exerted by the first elastic element on the first energy storage gear 3 coincides with its central axis. Then, the first drive gear 5 rotates in the counterclockwise direction to mesh with the center wheel 9, causing the center wheel 9 to rotate in the clockwise direction, and accordingly rotating the main shaft of the dual power source changeover switch, switching to the first power position, as shown in fig. 4.
Next, a process of switching the handle of the handle operating mechanism from the second position to the first position, resulting in switching the dual power supply changeover switch from the first power-on position to the double split position, will be described with reference to fig. 5 and 6.
As shown in FIG. 4, the handle is in the second position and the dual power transfer switch is in the first power position. When the handle 1 is rotated in the clockwise direction, the handle gear 2 is also rotated in the clockwise direction. The handle gear rotates clockwise to be meshed with the first energy storage gear 3, so that the first energy storage gear rotates anticlockwise, and the first elastic element 7 with one end mounted on the first energy storage gear deforms to store energy. At this time, the first driving gear 5 is held stationary by a second stopper installed on the frame, which prevents the first driving gear from rotating in the counterclockwise direction by the first elastic member 7. After the first elastic member 7 passes the "dead point" position, the first driving gear 5 is rotated in the clockwise direction by the elastic force of the first elastic member 7. Then, the first drive gear 5 rotates in the clockwise direction to mesh with the center wheel 9, causing the center wheel 9 to rotate in the counterclockwise direction, and the main shaft of the dual power transfer switch is correspondingly rotated to be switched to the double split position.
Next, a process of switching the handle of the handle operating mechanism from the first position to the third position, resulting in switching the dual power source changeover switch from the double split position to the second power source on position, will be described with reference to fig. 7 to 8.
When the handle 1 is rotated in the clockwise direction, the handle gear 2 is also rotated in the clockwise direction. The handle gear rotates clockwise to be meshed with the second energy storage gear 4, so that the second energy storage gear rotates anticlockwise, and the second elastic element 8 with one end mounted on the second energy storage gear deforms to store energy. At this time, the second driving gear 6 is held stationary by a third stopper installed on the frame, which prevents the second driving gear from rotating in the counterclockwise direction by the second elastic member 8. After the second elastic member 8 passes the "dead point" position, as shown in fig. 7, the second driving gear 6 is rotated in the clockwise direction by the elastic force of the second elastic member 8. The "dead point" position is the position: the elastic force exerted by the second elastic element on the second energy storage gear 4 coincides with its central axis. Then, the second drive gear 6 rotates in the clockwise direction to mesh with the center wheel 9, causing the center wheel 9 to rotate in the counterclockwise direction, and accordingly rotating the main shaft of the dual power source changeover switch to the second power position, as shown in fig. 8.
It is to be noted that the handle gear 2, the first drive gear 5 and the second drive gear 6 are distributed with teeth over only a part of the circumference. This enables the handle gear to mesh with only one of the first and second energy storing gears, but not both, during operation, and enables only one of the first and second drive gears to mesh with the sun gear, but not both, during operation. Specifically, during rotation of the handle from the first position to the second position or from the second position to the first position, the handle gear 2 can mesh with only the first power storage gear and not with the second power storage gear, and only the first drive gear can mesh with the sun gear and the second drive gear cannot mesh with the sun gear. During rotation of the handle from the first position to the third position or from the third position to the first position, the handle gear 2 can only mesh with the second energy storing gear and not with the first energy storing gear, only the second drive gear can mesh with the sun gear and the first drive gear cannot mesh with the sun gear.
In addition, in the present example, the handle gear, the first drive gear, and the second drive gear are shown as internal gears, but those skilled in the art will appreciate that the handle gear, the first drive gear, and the second drive gear may also be external gears.
The manual operating mechanism with the handle gear, the energy storage gear, the driving gear and the central shaft is described above, so that the manual operating mechanism provided by the invention has the advantages that when the dual power transfer switch is switched, the rotating speed of the movable contact is irrelevant to the switching speed, and the electric arc generated between the movable contact and the static contact is controllable and is within an allowable range, so that a front-end power supply or a rear-end load does not need to be disconnected, and the operation of a user is facilitated.
The above describes the switching of the handle of the manual operating mechanism from the first position to the second position, from the second position to the first position, and from the first position to the third position, resulting in the switching of the dual power source changeover switch from the double-split position to the first power source on position, from the first power source on position to the double-split position, and from the double-split position to the second power source on position. It should be understood that one skilled in the art could envision the transition of the handle of the manually operated mechanism from the third position to the first position in light of the teachings of the present invention.
Moreover, the technical features disclosed above are not limited to the combinations with other features disclosed, and other combinations between the technical features can be performed by those skilled in the art according to the purpose of the invention, so as to achieve the purpose of the invention.
