A device for driving impact and/or drilling tools on a hand power tool has a tool with a tool shaft having at least two drive grooves which are open toward the shaft end and at least one locking trough which is closed toward the shaft end. A driver for a radially displaceable locking body of a tool receptacle engage correspondingly in each drive groove and locking trough. For strengthening the driving, the locking body is provided with an axially extending, strip-shaped radial projection which engages in a correspondingly formed depression of the locking trough of the tool shaft for forming an additional drive flank. |
