1, housing or framework are born and passed to the gravity of the lever of vertical two the lever groups that are provided with of the utility model all by the rotating shaft on its balance pivot, reduced power and energy consumption.

2, on each crank arm on the utility model first bent axle two connecting rods are set and form two groups of connection rod set, and then drive two groups of symmetrically arranged lever groups, connection rod set and two generator for electricity generation outputs, because two groups of connecting rods on the crank arm of first bent axle all are symmetrical arranged, mutual balance or offset because lever swing departed from the partical gravity that produces behind the vertical line of fulcrum, therefore, the gravity of lever self reaches because the partical gravity that lever swing produces, can consumption of power and energy, and then make that power consumption of the present utility model is minimum, efficient is high.

3, the throw of eccentric of crank arm of the present utility model, connecting rod, lever design are reasonable, can use less power to do more living.

4, the bearing supporting is all adopted in hinged place of the present utility model, makes the surface friction drag of the utility model integral body little.
