Abstract
A drive system for releasably interconnecting a motor shaft of a rotary hand held power tool and an input shaft of an attachment device that is mounted thereon includes an elongated flexible drive shaft and an elongated output shaft. The flexible drive shaft is connected to the input shaft of the attachment device and includes an outer end portion with a non-circular cross-section configured to engage a complementarily shaped cavity of an output shaft operatively attached to the power tool motor shaft. The elongated output shaft is operatively connected to the motor shaft of the power tool. The output shaft defines a generally cylindrical outer configuration along its length and includes a rearward mounting portion for attachment to the motor shaft and an intermediate portion having the complementarily shaped cavity for receiving the flexible drive shaft.
