摘要 |
<p>The dowel (1) has a front region designed as an expansion area (5). A longitudinal hole (6) has a step like cross-section contraction (7) from rear towards the front at the transition to the expansion area or forwardly within the expansion area. An expanding mandrel (10) has a step like cross-section taper (13) from rear towards the front, and a holding region (11) located in front of the cross section taper. The holding region of constant cross section changes into a circulating spherical expanding surface (12), with which the mandrel is tapered to its front end.</p> |
