Gearshift rotating shaft

The utility model discloses a gear shifting rotating shaft which comprises a mounting shell, a sliding assembly and a plurality of gear assemblies, the sliding assembly and the gear assemblies are arranged in a cavity of the mounting shell, a driving motor is embedded in a sliding gear forming the sliding assembly, a driving wheel is fixed on an output shaft of the driving motor, and a guide railis arranged on the sliding shaft to limit the sliding track of the driving wheel. The whole structure is simple and compact, the driving motor is embedded, no extra space is occupied, the size of theassembled gear shifting rotating shaft is effectively reduced, after the driving motor is started, the sliding gear is driven by the driving wheel to automatically slide on the sliding shaft, meshingof the sliding gear and inner gear rings of different gear assemblies is achieved, and therefore gear switching is achieved; external force is not needed in the gear shifting process, and operation ismore convenient. 本实用新型公开了一种
