The fast connecting device provided by the invention is used for limiting the loading transmission shaft and the pin shaft through a central step hole and a plurality of peripheral step holes, compact in structure, reasonable in design and easier in ensuring assembly precision, has lightweight advantages, can also prevent the transmission and other related parts from impact damage while the efficiency of a whole assembly line is improved by 70 percent and can be widely applied to the fields of automobiles, new energy electric vehicles and other gear drives.
