Abstract
In a handpiece (2) having a housing (3), a drive sleeve (7) mounted therein, into which drive sleeve a tool (9) can be inserted with its shaft (11) and which drive sleeve is mounted in the housing to be rotatable around its middle axis (9a) by a drive, a releasable coupling for rotational locking connection of the shaft (11) in the drive sleeve (7), and a releasable coupling for axial connection of the shaft (11) with the drive sleeve (7), whereby each coupling is formed by a coupling recess (18) in the shaft (7) and a coupling pin (19) on the drive sleeve (7) engaging in the coupling recess, the two couplings are formed by at least one common coupling recess (18) and the common coupling pin (19) is mounted to be moveable between a coupling position engaging in the coupling recess (18) and a decoupling position releasing the coupling recess (18) and is biased into its coupling position and against the shaft (11) by the force of a spring (34).
