Abstract:
A connection for sections of a separable guide tube and of a drive shaft disposed therein, wherein said tube sections are axially interconnected, comprising:means for interlockingly coupling shaft sections of said drive shaft together, wherein ends of said shaft sections interengage one another, and wherein one of said shaft sections has an insertion end having a rotationally symmetrical, non-circular cross-sectional configuration, said interlocking means further including a driving sleeve coaxially secured on another one of said shaft sections, said driving sleeve having a coupling cross-sectional configuration that corresponds to said insertion end of said one shaft section, wherein said insertion end is introduceable into said driving sleeve, and wherein an axial introduction adapter is provided on said driving sleeve, wherein said introduction adapter has at least one inwardly projecting introduction ramp, which extends over an angle of curvature between two adjacent large diameters of said coupling cross-sectional configuration of said driving sleeve, and wherein said at least one introduction ramp includes an axially decreasing ramp surface that forms a shoulder for said insertion end of said one shaft section.
