摘要： The power tool includes a housing, an output shaft for fixing and driving a head to work, the output shaft being provided with a receiving portion extending out of the housing, a locking member for locking the head on the receiving portion of the output shaft, a fastener supported on the output shaft for fastening the locking member, and a driving mechanism rotatably displaced on the housing. The driving mechanism is operable to rotate along a first direction to make the fastener and the locking member screwed, and also is operable to rotate along a direction opposite to the first direction to loosen the fastener and the locking member. The power tool can assemble or disassemble the head quickly and provide a stable axial press to avoid the slippage of the head without any other auxiliary tools. Meanwhile, the operation method of the power tool is easy and reliable.
