Monocycle reciprocating device of gravitional force effect

The utility model relates to a monocycle reciprocating device of gravitional force effect, include: through actuating mechanism and toggle mechanism that the shifting fork bar links up, actuating mechanism can drive drive gear corotation and reversal, the toggle mechanism sets up two shifting fork bars including the driving lever that slides and set up on, two shifting fork bars are located drive gear's the both ends outside respectively, drive shaft one end is equipped with the screw rod, and the swivel nut screw of connecting the knee cup joints on the screw rod, set gradually first pivot, second pivot and third pivot on the pendulum rod, the driving lever is connected through first pivot to the pendulum rod, and the pendulum rod passes through second pivot connecting sleeve rod, and what the loop bar was coaxial cup joints in the sleeve, and the knee is connected to the sleeve other end, is equipped with the balancing disk on being located the pendulum rod of second pivot department, and the pendulum rod passes through the third pivot and rotates, set up a stop mechanism on the sleeve, a stop mechanism can prescribe a limit to the relative position between loop bar and the sleeve by the buckle, still is equipped with the lug on the driving lever, and the lug links up (b) with manual stop mechanism.
