The shaft (18) of the tool (14, 16) is a hollow cylinder which accommodates a bolt (20, 26), attached to the holding unit (12). A pulling bar (22) with a threaded end (28) is positioned inside the holding unit and the bolt is manipulated by the bar and fixed with a nut (30, 36, 38). The bar (22) is pulled into the hollow bolt (20, 26) and locked by the friction caused by the slightly conical shape of the bolt. Various tools can be attached to the stationary power driven machine as modules. |
