Abstract

A ratchet wrench assembly structure includes a wrench set (10), a ratchet set (20), a retaining ring (30), and a control set (40). The wrench set (10) includes a rod body (11) with a working end (111) and a fixing end (112). A tool hole (110) is defined on the working end (111). The flange (113) and the groove (114) are disposed spacedly on the fixing end (112). The ratchet set (20) includes a ratchet base (21), a ratchet component (22), and a latch member (23). The ratchet base (21) is disposed on the flange (113). The retaining ring (30) is fastened in the groove (114) and presses against the ratchet base (21). The ratchet base (21) is clamped by the ratchet base (21) and secured to the fixing end. The control set (40) is movably disposed on the ratchet base (21) and includes an operation key (41), and a pin (42) and a spring (43) assembled in the operation key (41). The pin (42) is combined with the spring (43) to elastically press against the latch member (23) to make the latch member (23) be engaged with the ratchet component (22).
