Screwdriver

摘要

The screwdriver for transmitting low torques in electronics and precision mechanics consists of a handle with a shank fixed therein and is characterised in that an axially protruding, axially movable pin or an element mounted for axial and rotational movement is arranged on the end face of the handle remote from the shank. The screwdriver can be turned with three fingers without the centring and bearing of the handle tip on the inside of the index finger being lost as a result of screwdriving. When exerting large axial forces with the inner surface of the hand, unpleasant pressure points (marks) on the hand are avoided.
