  • the number of groups of circular bores in the second engagement element is initially not specified, it is nevertheless advantageous if it is at least four or preferably even at least six, since each group of circular bores can in principle correspond to an expansion driver from the prior art , which can then be replaced by the expansion driver according to the invention.

  • This structural measure not only enables the second engagement element to be positioned relative to the first engagement element by mounting the second engagement element in different positions, but also the first engagement element can in turn be mounted in different positions or orientations, which increases the flexibility of the variable spreading driver according to the invention once can increase significantly.
