ABSTRACT:
An activation device for activating an engine of a power tool includes an activation unit, a clutch unit and a transmission unit, wherein the clutch unit is connected between the activation unit and the transmission unit. The activation unit includes a first spring disk and a second spring disk. When the activation unit rotates clockwise, the transmission unit rotates in the same direction via the clutch unit. When the first spring disk releases the energy to rotate the activation unit counter clockwise, the clutch unit disengages the activation unit from the transmission unit so that the second spring disk rotates the transmission unit to start the engine.
