Abstract

A screwdriver tool including a gear ratio arranged in a handle for multiplying a rotation angle transmitted from the hand to a blade protruding from the handle. A blocking element can be rotated from a release position, in which a first handle section can be rotated relative to a second handle section for the purpose of quick-action screwing, into a blocking position, in which a blocking element secures the blade to the handle in a rotationally fixed manner. The switching between the release position and the blocking position occurs by means of a push-button arranged in the tip of the handle, which is moved back into its starting position in a spring-loaded manner after being actuated.
