Abstract
An end effector includes: a tool holder; a tool which is attached in protruding fashion to the tool holder; a sleeve which is movable on the tool holder between a protective position in which it surrounds the tool and a usage position in which it is pushed towards the tool holder and can release at least a tip of the tool; and a blocking element which is movable, under control of a sensor for detecting a proximity of the end effector to a workpiece, between a blocking position in which it blocks the sleeve in the protective position, and a release position in which it allows a movement of the sleeve into the usage position.
