A positioning hook structure for a hand puller contains a base including a first and a second ends. A rotating member includes a first segment axially connected with the second end and a second segment having a handle. A central shaft set is axially coupled with the first segment and the second end. Two ratchets includes teeth arranged therearound and fixed onto one end of the central shaft set. The base includes a movable retaining member to abut against one of the teeth. The rotating member includes a movable pulling rod to abut against another tooth of the ratchet. A positioning hook includes third and fourth ends, with the third end including two sides including two insertions, and with the fourth end including a hooking portion extending outward. Thus, the positioning hook inserts in the holes of the base by using the insertions.
