发明名称 Hand-held machine tool
摘要 A hand power tool, in particular a drill hammer or jackhammer, is disclosed, which has a guide tube ( 11 ), a tool holder ( 24 ) that can be attached interchangeably to the guide tube ( 11 ), and a locking device ( 23 ) that locks the tool holder ( 24 ) to the guide tube ( 11 ), the locking device being manually releasable by means of an axial displacement of a slide sleeve ( 34 ) oriented away from the tool holder ( 24 ). To achieve a compact connection construction, which is economical in production terms, between the interchangeable tool holder ( 24 ) and the hand power tool, the tool holder ( 24 ) is embodied as insertable by an end portion ( 241 ) into a guide portion ( 111 ) embodied on the front end of the guide tube ( 11 ), in the inner wall thereof (FIG. 1 ).
