Das Befestigungsmittel 26 zur Erzielung der Formschlussverbindung in axialer Richtung 28 der Befestigungsachse weist eine nutförmige Aussparung 42 auf, die in Umfangsrichtung 20 um den Spindelhals 44 der Handwerkzeugmaschine 12 verläuft. Die nutförmige Aussparung 42 erstreckt sich dabei ringförmig um den gesamten Spindelhals 44. Grundsätzlich ist es jedoch auch denkbar, dass sich die nutförmige Aussparung 42 über einen eingeschränkten Teilbereich in Umfangsrichtung 20 am Spindelhals 44 erstreckt. Die nutförmige Aussparung 42 ist entlang der Befestigungsachse in Richtung der Werkzeugaufnahme 52 nach den vier stegförmigen Erhebungen 46 angeordnet. Zudem befindet sich die nutförmige Aussparung 42 beabstandet zu den vier stegförmigen Erhebungen 46 am Spindelhals 44.The attachment means 26 for achieving the positive connection in the

Ein erstes Bauteil 34 des Zusatzhandgriffs 32 umfasst ein Griffmittel 64 und ein halbkreisförmiges Aufnahmemittel 66 der Aufnahmeeinheit 30 zur Aufnahme des Spindelhalses 44 der Bohr- und/oder Schlagbohrmaschine (
Zur Sicherung des Zusatzhandgriffs 32 an dem Spindelhals 44 der Bohr- und/oder Schlagbohrmaschine in Umfangsrichtung 20 der Befestigungsachse weist das Aufnahmemittel 66 des ersten Bauteils 34 das Befestigungsmittel 18 auf. Das Befestigungsmittel 18 ist von gleichmäßig zueinander beabstandeten Aussparungen 48 gebildet, die in Umfangsrichtung 20 an einer dem Aufnahmebereich 70 zugewandten Seite des Aufnahmemittels 66 angeordnet sind. Die Aussparungen 48 erstrecken sich dabei entlang der Befestigungsachse auf einen Teilbereich des halbkreisförmigen Aufnahmemittels 66. Zur Sicherung des Zusatzhandgriffs 32 in axialer Richtung 28 der Befestigungsachse weist das Aufnahmemittel 66 das Befestigungsmittel 24 zur Erzielung einer Formschlussverbindung in axialer Richtung 28 der Befestigungsachse auf, das von einem rippenförmigen Befestigungselement 50 gebildet und in das Aufnahmemittel 66 eingepresst ist. Das als Bolzen ausgebildete rippenförmige Befestigungselement 50 ragt dabei in den halbkreisförmigen Aufnahmebereich 70 des Aufnahmemittels 66. Eine Haupterstreckungsrichtung 72 des rippenförmigen Befestigungselements 50 ist dabei senkrecht zur Befestigungsachse ausgerichtet (
