Hand-held machine tool, in particular hand-guided grinding machine

Abstract

A hand-held machine tool is provided with a split housing, the two parts of which are to be connected via a connecting device that is designed as a plug-in connection. The plug-in connection has a connection piece on the first housing part and an opposite connection piece on the second housing part. At least one section of the connection piece and of the opposite connection piece extends at an angle from the longitudinal axis of the connection piece.
