Device for controlling at least one attachment

A device for guiding at least one tool or auxiliary device, comprising a base part;

• at least one boom articulated with said base part in an articulation and having at least two members connected with one another by a connection and also having an end supporting the tool, the connection of said members with one another and the articulation of said boom with said base part having hinge points formed for swivelling movements in at least one plane, each of said at least two members being subdivided into two elements which are fastened to one another by pivot connections situated between said hinge points so that at least two of said pivot connections are provided in the device, said pivot connections being formed so that said elements are swivellable relative to one another over more than 360.degree., said pivot connections having axes extending in a longitudinal direction of said elements;
• and a supplemental arm composed of two elements connected with one another by a pivot connection.
