Hand machine tool with a hammer mechanism

摘要

A hand machine tool is equipped with a hammer mechanism, which has a hammer ( 1 ) that moves axially back and forth in a guide tube ( 2 ); a spring mechanism ( 4 ) is provided, which exerts a force on the hammer ( 1 ) and can set the hammer ( 1 ) into a movement toward a tool ( 3 ) that can be inserted into the hand machine tool. The hammer mechanism produces a very high individual hammering energy at a relatively low hammering frequency by virtue of the fact that after each impact, the hammer ( 1 ) is set into a motion counter to the force of the spring mechanism ( 4 ) in order to stress this spring mechanism and after the stressing of the spring mechanism ( 4 ), the hammer ( 1 ) is abruptly released again so that it flies toward the tool ( 3 ).
