The energy storage assembly 5 needs to collect the mechanical energy generated by the two directions of movement, which requires the transmission assembly to have a reversing structure to store the mechanical energy obtained by the two directions of oscillation in the energy storage assembly 5. The embodiment adopts two groups of jaw clutch mechanisms to realize reversing, and specifically: when the pendulum bob 1 swings in the first direction, the first jaw clutch mechanism 21 is engaged, the second jaw clutch mechanism 22 is separated, the first jaw clutch mechanism 21 transmits power, and the power input gear 3 transmits the motion of the pendulum bob 1 to the power output gear 4 through the first jaw clutch mechanism 21 and then to the energy storage component 5; when the pendulum bob 1 swings in the second direction, the second jaw clutch mechanism 22 is engaged, the first jaw clutch mechanism 21 is separated, the second jaw clutch mechanism 22 transmits power, and the power input gear 3 transmits the power of the pendulum bob 1 to the power output gear 4 through the second jaw clutch mechanism 22 and then to the energy storage component 5; the energy storage assembly 5 thus achieves the collection of mechanical energy moving in both directions.
