The invention relates to a rapid shoelace tying device which comprises a shoelace tensioning mechanism arranged on a shoe sole, and the shoelace tensioning mechanism comprises a micro gear motor, a gear set, a shoelace winding rod, a resisting part and a control switch electrically connected with the micro gear motor; the gear set comprises a driving gear and driven gears meshed with the two sides of the driving gear respectively, the driving gear is connected with an output shaft of the micro gear motor, and a plurality of shifting rods are arranged on the lower portion of the rotating shaft in the circumferential direction. Shoelaces are arranged at the lower parts of the shoelace winding rods. An output shaft of a gear motor drives a driving gear to drive two driven gears to rotate, the two driven gears rotate respectively to drive a shoelace winding rod to rotate, shoelaces penetrate to the lower portion of the winding rod from a vamp, and the ends of the two shoelaces are tied to the lower portion of the shoelace winding rod respectively. The shoelace winding rod rotates to enable the shoelace to be wound on the shoelace winding rod, the shoelace is tensioned, the gear set of the stopping part rotates, the failure rate is low, and the use experience of consumers is improved.
