The invention discloses an oil circuit structure for quickly adjusting a camshaft phaser. The oil circuit structure comprises a front cover plate, a rear cover plate, a stator and a rotor, wherein thestator is arranged between the front cover plate and the rear cover plate, and the rotor is arranged inside the stator. A stator locking pin hole is arranged in the stator, a locking pin seat is arranged in the stator locking pin hole, a locking pin sleeves the end portion of the locking pin seat, a locking pin spring is arranged between the locking pin and the locking pin seat, the rotor is provided with a rotor locking pin hole, and the locking pin is matched with the rotor locking pin hole. In the oil circuit structure for quickly adjusting the camshaft phaser, when the phaser is in a lagging state, engine oil already passes through a locking pin oil circuit to open the locking pin; and when adjustment to the advance state is required, the rotor rotates directly relative to the statorin the direction of a lagg
