摘要： A power tool includes a housing (1), a motor (2), an output shaft (4), a transmission mechanism (3), a cartridge (52) and a connecting shaft (51). The motor is disposed in the housing (1) and outputs rotary power. The output shaft is provided with a receiving hole disposed axially for receiving a tool head. The transmission mechanism transfers the rotary power from the motor (2) to the output shaft. The cartridge includes chambers (521) for accommodating a plurality of tool bits. The connecting shaft can axially move between a working position in which the connecting shaft passes through a chamber to force one of the tool bits into the receiving hole and a releasing position in which the connecting shaft releases the tool bits. The power tool also has limiting mechanisms (8, 8a, 8b) disposed between the housing and the connecting shaft. The limiting mechanisms have limiting blocks (81, 81a, 81b) which can shift between a first position and a second position. When in the first position, the connecting shaft is in the working position and the limiting blocks restrict the connecting shaft from moving in the direction away from the tool bits. When in the second position, the connecting shaft is in the releasing position and the limiting blocks allow the connecting shaft to move in the direction away from the tool bits. An operating method for the power tool is also disclosed.
