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).
