The utility model relates to a tool used for opening the bottle stopper, and is suitable for opening the corks in particular. The exiting bottle stopper opening tool always snaps the corks because the action area of the spiral suspension taper and the cork is small. The utility model includes a supporting body and a pull rod which moves up and down along the axial direction; the middle of the pull rod has a continuous groove with the sawtooth shape and is matched with a pair of strengthening handles with the sawtooth shape at the supporting body; the lower end of the pull rod has a hook and is matched with the pull rope imbedded in the bottle stopper, so as to realize the pull rod pulls the cork to move. Because the structures of the pull rod and bottle stopper are improved, the stress bearing area of the bottle stopper is greatly increased; the bottle stopper can not be broken or damaged in the pulling process, to bring the great convenience for user.
