The invention discloses a rotary oscillation reversing valve which is of a hydraulic reversing valve structure and comprises a valve body, a driving mechanism, a rotary mechanism and an oscillation mechanism, and the driving mechanism, the rotary mechanism and the oscillation mechanism are all arranged in the valve body and form corresponding working cavities. The driving mechanism is connected with the slewing mechanism, and the slewing mechanism is connected with the oscillating mechanism; the driving mechanism is used for driving the slewing mechanism; the swing mechanism is used for driving the oscillation mechanism to do rotary motion; the oscillating mechanism is used for controlling a main valve element of the oscillating mechanism to do linear reciprocating motion. According to the hydraulic reversing valve, the driving mechanism and the swing mechanism are matched to drive the oscillation mechanism to do rotary motion, the problem that hydraulic clamping is difficult to release after a valve element
