Handheld Instruments with Improved Coupling Structures for Functional Attachments of Handheld Instruments

摘要

The present invention relates to a drive shaft (6) of a body (2) of a hand-held appliance (1) to a driven part (7) of a releasable functional attachment (3) of a hand-held appliance (1). ) relates to a coupling structure (8, 9, 10) for bonding to. The coupling structure includes a coupling bush 8 , a coupling head 9 and a coupling spring 10 . The engagement head 9 is axially fixed in the functional attachment 3 , and the engagement bush 8 is axially displaceable in the body 2 . The engagement spring 10 is accommodated in the body 2 and forces the displacement of the engagement bush 8 towards the engagement head 9 when the functional attachment 3 is attached to the body 2 . The bonding structure is compact in particular in the axial direction of the bonding structure and in particular within the functional attachment.
