Patent ID: 7757922

Claim:
A power beating device using the inclined plane principle comprising: a spring ( 20 ) for storing and releasing energy, an impact unit ( 40 ) driven by the spring ( 20 ) being a round cylinder with a hole at a lateral side thereof; a driving rotary cylinder ( 10 ) having a hollow center for receiving the impact unit ( 40 ); an upper edge of the driving rotary cylinder ( 10 ) being formed as at least one wedge helical driving surface ( 11 ); a driving pin ( 41 ) inserting into the hole at a lateral side of the impact unit ( 40 ); a lower side of the spring ( 20 ) resisting against the driving pin ( 41 ); and in assembly state, the driving pin ( 41 ) being located at an upper side of the wedge helical driving surface ( 11 ); a driven gear ( 12 ) at an outer periphery of the driving rotary cylinder ( 10 ) below the wedge helical driving surface ( 11 ); the driven gear ( 12 ) being driven to rotate in a driving bush ( 50 ); a driving bush ( 50 ) installed at a lower side of the driving rotary cylinder ( 10 ); the driving bush ( 50 ) having a hollow center for receiving a lower end of the driving rotary cylinder ( 10 ); an upper end of the driving bush ( 50 ) having a flange extending therefrom; an actuator ( 30 ) formed aside a driving unit ( 2 ); and a transfer gear ( 31 ) installed with an outer shaft of the actuator ( 30 ); the transfer gear ( 31 ) being engaged to the driven gear ( 12 ) of the driving rotary cylinder ( 10 ); and wherein as the transfer gear ( 31 ) rotates, the driven gear ( 12 ) will be driven to rotate along the driving bush ( 50 ); at the same moment, the driving pin ( 41 ) will be driven so as to further drive the impact unit ( 40 ) to compress the spring ( 20 ) to store potential energy; and wherein an upper edge of the driving rotary cylinder ( 10 ) is formed with at least two wedge helical driving surfaces ( 11 ).
