It may also be provided that the respective spring tongue is loaded radially inwards by a 32 sliding over the sleeve 50 through a latch head 34th The clamping sleeve 50 is releasably connected via a screw thread 52 with a threaded ring 54th The threaded ring 54 is slidable on the shaft 5, wherein a shoulder 58 serves at the transition to the sleeve 10 as a stop. On which the shoulder 58 opposite side of the threaded ring is loaded by a spring ring 60 54, which in turn is supported on a press-fitted on the shaft 5 retaining ring 62nd The spring ring 60 presses the ring nut 54 in the absence of external forces against the shoulder 58, so that the entire spring ring 30 is enclosed, including the locking heads 34 in this rest position of the clamping sleeve 50th Advantageously, the sleeve 50 is dimensioned such that it shown in the rest position as shown in Fig. 1, also covers the gap between ring nut 54 and retaining ring 62 in which the spring ring 60 is located so that said spatial region is closed to the outside and in front of is protected penetration of dirt. The sleeve 50 has an annular flange 51 which serves for better handling during retraction of the sheath. - 11 -

For coupling a Bohraufsatzes 3 on the retaining part 1, the clamping sleeve 50 is retracted by means of the annular flange 51 so that the spring tongues 32 and the latching heads 34 are released so far that they can move radially outwards. Then, the shaft 16 is inserted into the bore 14 until the shoulder 22 abuts the edge 20 of the sleeve 10 and the latching heads of the flexible tongues 32 engage in the annular groove 40 34th Subsequently, the drill is provided rotated relative to the retaining member until the spring tongues engage in the longitudinal grooves 38 of the Bohraufsatzes 3 32nd Subsequently, the clamping sleeve 50 is released, then 60 and the threaded ring 54 is pressed to the drill bit 3 out until the threaded ring 54 abuts the shoulder 58 and the clamping sleeve 50, the locking heads 34 includes, so that they no longer radially through the spring ring can be moved outside and the spring tongues 32 are held in the grooves 38 and the locking heads 34 in the groove 40 surely. To release the Bohraufsatzes 3 of the holding member 1, the clamping sleeve 50 is retracted again, so -that the locking head 34 can move radially outwards and the drill bit 3 can be removed. Advantageously, the groove 40 is designed so that the one part of the locking head is indeed held securely in the groove, but the drilling tool can be withdrawn to replace 3 by hand when the clamping sleeve is retracted 50th

In the course of a drilling operation body fluids and small bone particles can pass into the interstices of the support member 1 and impair the mobility of the individual components. Therefore, it is provided that the retaining member can be disassembled for cleaning. For this purpose, the threaded ring 54 to bores 70 which can be brought into alignment with holes 72 at the bottom of the bore fourteenth Through the bores 70 and 72 holding mandrels of a holding tool 76 can be inserted is now 74 in order to fix relative to the holding tool 76 to the threaded ring 54th In general, a plurality of holding mandrels be provided 74 in the holding tool 76 in - 12 -

Fig. 7, however, only one such pin is shown for simplicity. When the threaded ring is fixed by the mandrels 74 of the holding tool 76 54, the clamping sleeve 50 can be unscrewed from the threaded ring and are withdrawn in the direction of the clutch 7 through. To facilitate the twisting of the clamping sleeve 50, the annular flange 51 is provided with recesses 78th Alternatively, it can also specially designed for the application of a turning tool, for example in a polygonal shape, may be formed. When the clamping sleeve 50 is removed, the space between the threaded ring 54 and the clamping ring 62 is easily accessible and therefore can be readily purified.

Various alterations and modifications of the embodiment described above are possible. In particular, the drill 3 and the retaining part 1 may be formed complementary to the illustrated embodiment, ie, the drill has a receiving sleeve with a bore into which a shaft of the holding part is inserted to the axial centering. From the standpoint of being able to reuse as many parts of the system, it is advantageously continue arranging the clamping sleeve and optionally also the spring tongues on the holding part. However, in principle it is also possible to provide the spring tongues and / or the clamping sleeve and on the drill bit. In particular, it is possible to provide the clamping sleeve on the holding part and the spring elements on the drill bit, in which case the spring elements can be fully released to a retraction of the clamping sleeve.

The holding member 1 need not necessarily have a coupling 7 for a drill or, more generally, be releasably connected with a drill. Rather, the retaining member may also be fixedly connected to the drill or form an integral part thereof.

The features disclosed in the foregoing description, the drawings and the claims of the invention may, both separately and in any combination be essential to implementing the invention in its various embodiments.
