As shown in fig. 1 to 5, an energy storage handle pushing mechanism includes a push rod 10, an air cylinder 11, a bracket 12, a lever 13, and a support rod 14, where the push rod 10 is connected to the air cylinder 11 and can reciprocate under the pushing of the air cylinder 11, and preferably, the air cylinder 11 may be replaced by a motor drive, a gear drive, a lead screw drive, a module drive, or the like, as long as the push rod 10 can be pushed to move, and in this embodiment, the air cylinder drive is adopted.
The cylinder 11 is fixed to the lever 13 by screws, but the cylinder 11 may be connected to the lever 13 by riveting, welding, or the like, as long as the cylinder 11 is fixed to the lever 13, and the present invention is not limited thereto. In this embodiment, a connecting plate 16 is further disposed between the cylinder 11 and the lever 13, and the connecting plate 16 is fixed to the lever 13 and the cylinder 11 by screws, so as to fix the cylinder 11 and the lever 13.
Preferably, an adjusting screw 132 is further disposed between the lever 13 and the connecting plate 16, and the height of the cylinder 11 can be adjusted by adjusting the adjusting screw 132, so as to adapt to circuit breaker products with different specifications.
With reference to fig. 1 to 4, one end of the push rod 10 is connected to the cylinder 11 by a rivet, and the other end of the push rod is provided with an arc-shaped protrusion 101 capable of pushing the energy storage handle 200, when the cylinder 11 moves, the push rod 10 moves along with the cylinder and is matched with the arc-shaped structure at the bottom of the energy storage handle 200, so as to push the energy storage handle 200 out of the cavity of the circuit breaker. Of course, the push rod 10 may also be connected to the cylinder 11 by means of screw fixation, welding, or the like, and only the push rod 10 needs to be fixed to the cylinder 11, which is not limited herein.
A first limiting block 121 and a second limiting block 122 are arranged on the bracket 12, the lever 13 is located between the first limiting block 121 and the second limiting block 122, one end of the lever 13 is connected with the bracket 12 through a rotating shaft 131, and the other end of the lever 13 freely moves relative to the bracket 12 and can rotate around the bracket 12 by taking the rotating shaft 131 as a center; the first stopper 121 and the second stopper 122 limit the maximum movable range of the lever 13 under the elastic force of the spring 15: namely: when the lever 13 contacts with the first stopper 121 or the second stopper 122 in the rotating process, the lever is limited by the first stopper 121 or the second stopper 122, so that the lever cannot rotate any more. The first stopper 121 and the second stopper 122 may be integrally formed with the bracket 12, and may also be fixed to the bracket 12 by screws, rivets, welds, or the like, in this embodiment, the first stopper 121 and the second stopper 122 are fixed to the bracket 12 by screws respectively.
A supporting rod 14 is arranged between the lever 13 and the second limiting block 122, one end of the supporting rod 14 penetrates through the second limiting block 122, the other end of the supporting rod 14 is provided with a limiting block 141, and the limiting block 141 is located below the lever 13 and is in contact with the lever 13.

The specific working process of the energy storage handle pushing mechanism in combination with the testing process of the energy storage handle is described as follows:
as can be seen from fig. 4 and 5, the arc-shaped protrusion 101 needs to push the energy storage handle 200 clockwise and downward to push the energy storage handle 200 out of the circuit breaker cavity. Firstly, the cylinder 11 moves to drive the push rod 10 to move towards the direction close to the energy storage handle 200 until the arc-shaped bump 101 on the push rod 10 contacts with the arc-shaped structure 201 on the energy storage handle 200, the energy storage handle 200 can rotate anticlockwise around the axis of the energy storage handle 200 under the thrust action of the push rod 10, and in the rotating process of the energy storage handle 200, a downward reaction force can be generated on the push rod 10 so as to drive the lever 13 to rotate clockwise and downwards around the rotating shaft 131, when the energy storage handle 200 is completely pushed out of the cavity of the circuit breaker, the cylinder 11 stops moving, and the detection mechanism starts to detect the energy storage handle 200.
When the lever 13 rotates clockwise and downwards in the process of pushing out the energy storage handle 200, the spring 15 is compressed; after the cylinder 11 stops moving, the energy storage handle 200 no longer generates a downward reaction force on the push rod 10, at this time, the lever 13 stops rotating, the elastic force of the spring 15 is released, and under the elastic force of the spring 15, the lever 13 starts to rotate counterclockwise and upward, so that the cylinder 11 and the push rod 10 are driven to reset.
