Abstract (en)
[origin: WO2020147002A1] The present invention relates to a power tool and a power tool kit. The power tool comprises a battery receptacle defining a battery receiving space, the battery receptacle arranged to be removably coupled with a battery pack; an actuator moveable between ON and OFF positions to selectively operate a drive means of the power tool for driving a tool element; and a linkage mechanism operably connected with the actuator, wherein the linkage mechanism comprises a first linkage member being movable substantially linearly along a movement axis between a first position that prevents the battery pack to couple with the battery receptacle and a second position that allows the battery pack to couple with the battery receptacle. By utilising a mechanical linkage mechanism, the present invention provides a more reliable and cheaper mechanism to ensure the safety of users and prevent harm due to failure of any electronic mechanism, such as PCB board failure.
