Abstract

The invention relates to a hand machine tool (10), comprising a housing (12, 121, 122) of shell-like construction, a motor housing (20), likewise of shell-like construction, with a free end. Said tool may be more easily maintained and repaired, whereby the motor housing (20) has a hinged cover (60) on the end thereof, which may be opened in a captive manner.

Description

technical field [0001] The invention relates to a hand-held power tool. Background technique [0002] Hand-held power tools are known, in particular hand-held drills and percussion drills with a pot-shaped housing, in which a closure cap is arranged at the end of the cylindrical housing. However, this cover can only be opened with difficulty using a separate tool, and the closure cover is not suitable here, or only very conditionally suitable, as a maintenance cover for replacing carbon brushes. In addition, known covers of this type do not reliably prevent falling off of the housing. Contents of the invention [0003] The object of the present invention is to provide a hand-held power tool which is structurally stable and which overcomes the above-mentioned disadvantages of the hand-held power tools of the prior art. [0004] According to the invention, a hand-held power tool is proposed with a housing consisting of two longitudinally separated housing shells which tran...
