摘要 |
A device on power tools for driving impact and/or drilling tools has a tool having a tool shaft provided with at least two drive grooves open toward a shaft end and at least one locking trough closed toward the shaft end, in which correspondingly a driver and a locking body of a tool receptacle engage. For increasing the driving, at least one axial formation is provided on a projection of the thicker portion of the tool shaft to a thinner insertion end of the tool at the end side for an additional driving, which axial formation cooperates with an axial formation, for example a tooth, of a driven part, for example an auxiliary strip, at the end side of the tool holder. |
