초록 ▼

In a tool holder for securing a tool in a hammer drill in a form-locking manner, locking elements are radially displaceably mounted in a guide member. An adjustment ring is threaded onto the guide member and by rotating the adjustment ring relative to the guide member, the locking elements can be adjustably tightened or loosened. The locking elements seat in closed end recesses in the shank of the tool to be secured. The adjustment ring can be locked in different rotational positions by an interlocking tooth arrangement. Teeth are provided on the adjustment ring and on a fixing sleeve axially slidably positioned on the guide member. The fixing sleeve can be moved axially between a position for locking the adjustment ring and another position permitting the adjustment ring to be rotated relative to the guide member. The surface on the adjustment ring adjustably positioning the locking elements is frusto-conically shaped so that the locking elements are radially displaceable for engaging tool shanks of different diameters.

A tool holder arranged to receive and secure a tool in a hammer drill, comprising an axially extending guide member, a plurality of locking elements supported in said guide member and said locking elements are radially adjustably positionable relative to said guide member for engagement within closed end recesses in the shank of the tool inserted into the tool holder, an adjustment ring is mounted on said guide member for adjustably positioning said locking elements, said adjustment ring being rotatable relative to said guide member for effecting the radial adjustment of said locking elements, a fixing sleeve axially slidably mounted on said guide member and displaceable between a first position for locking said adjustment ring and a second position for releasing said adjustment ring for rotation relative to said guide member, said adjustment ring can be locked by said fixing sleeve in at least two positions for each complete turn of said adjustment ring relative to said guide member, and a toothed construction is provided on said fixing sleeve and a counter toothed construction is on said adjustment ring so that the inter-engagement of said toothed construction and said counter toothed construction locks said adjustment ring against rotation relative to said guide member, and said toothed construction on said fixing sleeve extends in the axial direction thereof and faces radially outwardly and the counter toothed construction on said adjustment ring extends in the axial direction and faces radially inwardly so that said toothed and counter toothed constructions interengage in a telescoping manner.
