<p>An oscillating power tool comprises a casing, an electric motor arranged inside of the casing, a motor shaft and an output shaft driven by the electric motor, and an eccentric drive mechanism arranged between the motor shaft and the output shaft. The eccentric drive mechanism can be selectively switched between at least two working modes. Different working modes of the eccentric drive mechanism provide the output shaft with different oscillation angles, thereby enabling an oscillating power tool to satisfy different functional requirements and be applicable to different work environments.</p>
