Transmission machinery capable of being assembled with electric bicycle to form four-limb training device

The invention provides transmission machinery capable of being assembled with an electric bicycle to form a four-limb training device. The transmission machinery comprises two wheel gears, a chain, a transmission rod, a ball-shaped clip and the electric bicycle (or the electro-tricycle), one wheel gear is connected at the left end of a middle shaft of the electric bicycle, the other wheel gear is connected at the upper end of a sloped beam of the electric bicycle by a shaft, and the two wheel gears are connected by a chain. One end of the transmission rod is connected on the wheel gear of the upper end of the sloped beam by a bearing and a shaft, the other end of the transmission rod is connected with one end of the ball-shaped clip, and the other end of the ball-shaped clip is connected on a handle of the electric bicycle. The transmission machinery is reasonable in structure, convenient to operate, easy to manufacture and install, assembled by the electric bicycle, and high in four-limb moving exercise efficiency, not only has a coordination function, but also can adjust frequency of four-limb moving exercise, increases function of the electric bicycle, improves utilization rate, and saves a large amount of materials and manpower. The transmission machinery is little in disposable investment, low in construction cost, and easy to popularize.
