A single-handed folding device comprises a slidable pressing means having flanges, a rivet for slidably holding the slidable pressing means, slidable keys for performing locking operation, and wires with one end fixed to the slidable pressing means and the other end fixed to the slidable keys. While the slidable pressing means is moved with relation to the rivet, the wires will be tensioned, which in turn cause the slidable keys to be pulled to an opening position so as to loosen the locking means. Further, a spring is arranged at the center of the slidable pressing means so that a force should be exerted during pressing the slidable pressing means. In addition, the single-handed folding device further includes sliding rings to facilitate the movement of the wires.
