The invention relates to a hand strap driving system. The hand strap driving system comprises a pressing mechanism, a driving wheel and a driving mechanism driving the driving wheel to rotate. The pressing mechanism comprises a fixed support, an adjustable support and a sliding wheel connected with the adjustable support in a rotating mode. A hand strap winds around the driving wheel and is located between the sliding wheel and the driving wheel. The adjustable support is provided with sliding grooves, the sliding grooves are formed in the radial direction of the driving wheel, and the fixed support is provided with fasteners matched with the sliding grooves. The hand strap winds around the driving wheel and is located between the driving wheel and the sliding wheel. Through the pressing mechanism, the friction driving force of the driving wheel on the hand strap is increased, and therefore the phenomenon that after getting wet in rain, the hand strap slips because the friction driving force between the hand strap and the hand strap driving wheel is reduced can be avoided, and the safety of passengers can be guaranteed. The gap between the sliding wheel and the driving wheel can be adjusted by adjusting the installation positions of the sliding grooves in the adjustable support, and therefore the friction driving force of the driving wheel on the hand strap can be adjusted and the applicability of the hand strap driving system can be higher.
