bohrfutter and, in particular, the schlagbohren

摘要

The adapter sleeve (9) can be turned in relation to the adapter ring (8). First stops limit the movement form-fittingly in both directions. The locking element is positioned between the ring and the chuck's body (1). The locking members are moved between being engaged and released by turning the sleeve in relation to the ring. An engaging mechanism (17) with two engagement positions is fitted between sleeve and ring. In one position the locking element is engaged, in the other position it is released. A coaxial intermediate ring (18) can be fitted between sleeve and ring. It has the ring-side parts for the first stops, the locking element and the engaging mechanism. It has a collar that surrounds the adapter ring not allowing any turning.
