Abstract
A walking type labor-saving two-dimensional multistage double-connecting-rod lever pedaling ground tricycle is characterized in that a group of labor-saving two-dimensional multistage double-connecting-rod levers for geometric multiplication are respectively arranged on the left side and the right side of a support, the number of stages can be 2, 3, 4, 5 or more, a supporting rod is connected and arranged at the rear part of each group of levers, and a pedaling ground wheel is arranged at the tail end of each supporting rod. When the left pedal drives the left geometric multiplication labor-saving two-dimensional multistage double-link lever to move towards the rear lower part, the left stay bar drives the left pedaling ground wheel to pedal the ground towards the rear lower part so as to lead the vehicle to move forwards. When the right pedal drives the right geometric multiplication labor-saving two-dimensional multistage double-connecting-rod lever to move towards the rear lower part, the right support rod drives the right ground pedaling wheel to pedal the ground towards the rear lower part so as to lead the bicycle to move forwards. The invention achieves the effect of saving labor by two aspects of stepping on the ground and propelling through a two-dimensional multistage double-connecting-rod lever which is multiplied by geometry and saves labor. The double-connecting-rod longitudinal and transverse two-dimensional arrangement fully utilizes space. The invention has the advantages that: the structure is firm, and the riding is labor-saving.
