A pull handle structure of a hand puller contains a base including two opposite holes to insert two shafts respectively, with each hole including a ratchet. A pulling handle includes a rotating member with two side plates, each including first and second ends. Each first end includes an axial connecting portion on which a circular opening is formed so that the rotating member swings axially relative to the base. The side plate includes a sliding rail. Between the two side plates is defined a movable retaining element to contact with the ratchet. A movable bar includes two elongated stems and a grip rod defined between the two elongated stems. Each elongated stem is fitted in the sliding rail to move slidably. Between the rotating member and the movable bar is defined a locking device to obtain a positioning purpose when the movable bar is expanded and retracted.
