1. An oscillating power tool, comprising:

  • a housing;

    a motor contained in the housing;

    a drive shaft driven by the motor to output a rotary movement;

    an output shaft being configured to be driven by the drive shaft and oscillate about its own axis at a certain oscillating angle; and

    an eccentric transmission mechanism being configured to convert the rotary movement of the drive shaft to an oscillating movement of the output shaft, the eccentric transmission mechanism comprising;

    an eccentric device mounted on the drive shaft, and a fork assembly connecting the eccentric device with the output shaft;

    the eccentric device comprises at least two drive members, the fork assembly comprises a first fork member and a second fork member, the first fork member has a first mating portion being configured to mate with the drive member and a second mating portion being configured to mate with the second fork member, the second fork member is configured to couple with the output shaft, the oscillating power tool further comprises an adjusting mechanism disposed in the housing, and the adjusting mechanism is operable to adjust the first fork member to move, so that the first mating portion abuts against different drive members, the second mating portion abuts against different parts of the second fork member, thus the output shaft is adjusted to output different oscillating angles.
