Claim:
A ratchet tool for tightening and loosening objects including screws and/or nuts and the like, comprising: a handle; a receiving piece; a ratchet mechanism which operatively connects said receiving piece with said handle; an electric motor with which torque is transferred to said receiving piece by a transmission via a connection between said electric motor and said receiving piece; a coupling provided for disconnecting said connection, said coupling being arranged in said transmission and having a first coupling component and a second coupling component; and a switch electrically and mechanically configured to separate and to connect said two coupling components so that said coupling is disengaged and engaged, respectively, wherein said switch is a single switch configured for turning said electric motor on and off and for actuating said coupling, wherein said switch is configured as a sliding switch that interacts with a spring which, when said switch is displaced, connects said first coupling component with said second coupling component in the connection via a spring applying a spring force to said first coupling component in a direction of said second coupling component.
