For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of bicycle speed-varying unit is held up device, it includes the balladeur train service portion of a groups of motors, a limit base and a bicycle speed-varying unit, the transmission shaft ora terminalis of this groups of motors is provided with a thread segment, the body of this limit base is provided with a limited post and transmission shaft that should groups of motors is provided with one wears the open-work of rank for transmission shaft, and this balladeur train service portion is provided with one first functional hole and one second functional hole; This thread segment is engaged in first functional hole of the balladeur train service portion of this bicycle speed-varying unit; This spacing column sleeve is held in the mouth in second functional hole of the balladeur train service portion of bicycle speed-varying unit.
Groups of motors body of the present utility model is provided with at least more than one first lockhole.
Locating part of the present utility model is a C type latch closure.
Limited post end of the present utility model is provided with an annular groove, when holding in the mouth second functional hole in its balladeur train service portion of this bicycle speed-varying unit for this spacing column sleeve, can be sheathed on this annular groove for a locating part.
Limit base of the present utility model is provided with second lockhole with its coupling to position that should its first lockhole of groups of motors.
Compared with prior art, the beneficial effect that the utility model had is: the thread segment of the utility model groups of motors transmission shaft is engaged in first functional hole of the balladeur train service portion of bicycle speed-varying unit; This spacing column sleeve is held in the mouth in second functional hole of the balladeur train service portion of bicycle speed-varying unit, so just can be by the running of its transmission shaft of groups of motors, do forward or displacement backward with the balladeur train that drives this bicycle speed-varying unit, in order to do switching to stir bicycle chain row culture speed change in real time, and make its speed change more convenient with accurately.
