Electric hand tool, in particular drill

An electric hand tool, comprising a housing having a housing axis, an electric motor received in said housing and having a motor shaft parallel to said housing axis;

• a work spindle driven by said electric motor and having spindle end projecting out of said housing;
• a transmission gearing located between said electric motor and said work spindle so that said work spindle is driven by said electric motor via said transmission gearing;
• a bearing provided for said work spindle, said housing being divided along a dividing line into a front housing part which contains said bearing for said work spindle and a rear housing part which contains said electric motor and are rotatable relative to one another so that said work spindle extending in said front housing part can occupy a plurality of angles relative to said motor shaft and said housing axis;
• a manually operating catch lock for stopping said housing parts in a selected angular position relative to one another, said transmission being formed so that a torsionally rigid transmission of force from said motor shaft of said electric motor to said work spindle is provided in said transmission gearing in every angular position of said housing parts relative to one another;
• an intermediate flange arranged in the region of said dividing plane between said two housing parts and rotatably supported at said front housing part and connected with said rear housing part, said dividing plane being located so that a rotational axis of said intermediate flange encloses an angle of 90.degree. relative to an axis of said motor shaft, said catch lock having a ring of catch recesses arranged at equidistant intervals and is held at said intermediate flange so as to be fixed with respect to rotation, and two locking pins supported so as to be radially displaceable in said front housing part, engage in diametrically opposite ones of said catch recesses, and are displaceable against a spring force, two unlocking knobs via which said two locking pins are displaceable at opposite sides of said front housing part and which are aligned with one another transversely to said work spindle for lifting out of said catch recesses, said unlocking knobs being arranged at said front housing part so that they can be gripped between a thumb and finger of one hand for a displacing movement in opposite directions.
