Abstract
The paddle arm of this labor saving bicycle is a paddle arm adjustable mechanism with its arm fixed with the exterior terminal of an differential axle and a core axle slidingly engaged in the differential axle, wherein the exterior terminal of the core axle is hinge connected with a swing bar, and a boom which protrudes from the arm to hinge connect the paddle. A coaxial synchronizing gear and an eccentric gear are respectively contacted with the left and the right differential axles. An eccentric axle is suited with the left and the right eccentric gears and is suited with a crankshaft with a connection bar to hinge connect the crankshaft the left and the right core axles. The boom drives the arm and the differential axle and interlocks the eccentric axle to coil around the eccentric gear central axle to rotate, the crankshaft repeatedly swings forwardly and backwardly to drive the core axle to rotate to-and-fro and the swing bar drives the left and the right arm to contract. The diameter of this vehicle paddle arm holds the line, and arm of force lengthens when the forcing for a half circle and shortens contrariwise, thereby reducing the energy consumption of drivers by 20-30 percent and properly utilizes the energy. This vehicle is also provided with a gravity projection device to transform the gravity vertical fluctuation into horizontal driving force. The elastic energy storage device of this vehicle stores energy when decelerating and braking with its torque releasing energy to drive this vehicle, also no resistance is caused when backing the vehicle due to a backing trigger.
