Beschreibung
Zusammenfassung:	A power tool includes a transmission mechanism provided with transmission gears for making an output shaft output different rotational speeds, where the number of transmission gears is greater than or equal to 3; the transmission mechanism includes multi-stage planetary gear sets; each stage of the multi-stage planetary gear sets includes one layer of planet gears in an axial direction; the total number of the multi-stage planetary gear sets is less than or equal to the number of transmission gears; and among the multi-stage planetary gear sets in the multiple stages, a first-stage planetary gear set closest to a motor shaft includes a first drive state and a first variable state, and any one of the remaining planetary gear sets is connected to a clutch mechanism.
