Abstract

An arrangement of a housing and a guide tube is provided wherein one end of the guide tube is held in the housing. The position of the guide tube is adjustable relative to the housing in the direction of the longitudinal center axis of the guide tube. A rotation stop stops swiveling of the guide tube relative to the housing and includes a guide part. The guide part is mounted in one of the guide tube and housing. A longitudinal wall runs in the direction of the axis on the other one of the guide tube and housing. The longitudinal wall interacts with the guide part during swiveling of the guide tube about its axis. The guide part is tiltable relative to the guide tube about a tilt axis. The tilt axis runs along the guide tube and at a distance (a, b) from the axis of the guide tube.
