Abstract
The inventive device includes a casing, inside of which the body is accommodated that has the hydraulic striking mechanism, inside of which a bush is mounted for guiding a tool. Said tool is held in a manner that enables it to rotate in the guiding bush and its horizontally displacement therein is limited by a cotter. The guiding bush includes at least one non-circular peripheral area that interacts with an area having a complementary shape that is made in the front of the casing in order to limit the rotation of the bush and thus of the body relative to the casing.
