    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).
