Abstract
A dual-gearshift forward backward control mechanism installed in a remote control toy car to control forward/backward motion and high/low speed gearshift by means of power transmission through a set of gears and two idle gears and the shifting of a switching gear on the polygonal middle section of the output shaft of the mechanism between two of the gears and the effect of the centrifugal force of a swivel block at one of the gears.
