A two-fold four-wheel golf bag cart folding device comprises: a lower cart frame; an upper cart frame; a rear wheel stand; a pull rod; a front wheel set; a locking mechanism, installed between an upper end of the upper cart frame and a lower end of the handle module, and having a function of fixing an angle between the upper cart frame and the handle module; and a four-link-rod mechanism, installed among the handle module, the rear wheel stand and the pull rod. The front wheels can be closed in synchronously while rear wheels are being folded, and the four wheels touch the ground simultaneously.
