Abstract
The present specification relates to a power tool comprising an input shaft and an output shaft and a two-speed power transmission comprising a planetary gear and a gear shift assembly for directing torque through or past the planetary gear comprising a driving member, a driven member and an axially movable coupling sleeve arranged to intercouple in a first position the driving member and the driven member and to intercouple in a second position the planetary gear and the driven member. A linear actuator is arranged to displace the coupling sleeve between the first and second position, wherein the linear actuator comprises a linearly movable push bar arranged for displacing the coupling sleeve. The present specification also relates to a method in and a two-speed power transmission for such a power tool.
