ABSTRACT:
A speed change gear device is disclosed. A speed change gear box has an input gear. The lower gear is firmly secured with a gear shaft. A speed change disk is installed between two gears mounted on a gear shaft. A movable piece is placed in the annular groove of a speed change disk. A lower connecting plate is mounted at one side of the movable piece. Another end of an upper connecting plate is installed to a driving rod. Another end of the driving rod is connected to a linkage. Another end of the linkage is firmly secured to a gear switching rod. Thereby, by moving the gear switching rod, a switching rotary shaft can rotate so that the movable piece move the speed change disk. Thus the gears are switched to move forwards, move rightwards or to an idle gear.
