A golf bag has a cord, a bottom frame and a top frame. The bottom frame has a cover and a bottom cuff received therein. The bottom cuff is pivotally mounted to the cover and has a bevel surface, a lever holder and a lever received in the lever holder and tied to the cord. The top frame has a cord guide for guiding and branching the cord and two leg holders tied to two branches of the cord and abut against the cord guide. When the golf bag is tilted, the bevel surface rests on the cover, the cord is dragged down to pull and extend out the two leg holders to stand on the ground. As the cover stay intact when the bottom cuff tilts, the golf bag can stably stand and requires a simplified cord linking design.
