Adapter for a power tool

摘要

An adapter for a power tool is disclosed which comprises a drive shaft that can be connected to an output shaft of the power tool in a rotationally fixed manner. There is a receiving connector on the power tool. On the adapter there is provided an assigned sleeve that can be pushed onto the receiving connector, and which comprises a clamping ring, which acts together with locking members in order to effect locking of the sleeve on the receiving connector when in a closed position, the clamping ring being held so as to be movable in the axial direction and being preloaded in the direction of the closed position. The locking members act together with the clamping ring in such a way that locking is effected automatically in the closed position when the adapter is pushed onto the power tool as far as the closed position, and a release of the adapter from the closed position can be effected through an axial movement of the clamping ring against its preload.

1. A power tool comprising an output shaft that can be driven rotatingly, and an adapter, wherein said adapter comprises:
a receiving connector provided on a first part selected from the group consisting of the power tool and the adapter; a sleeve provided on a second part selected from said group, said sleeve being configured so as to allow sliding of said sleeve on said receiving connector into a locking position, wherein said sleeve is locked on said connector; a clamping ring being arranged on said sleeve movable in an axial direction thereof, said clamping ring having a locking position being associated with said locking position of said sleeve and having a released position allowing movement of said sleeve together with said clamping ring towards said locking position; a locking arrangement cooperating with said clamping ring and said receiving connector in order to effect locking of said sleeve on said receiving connector when being in said locking position; and at least one spring element arranged pivotably on said sleeve for securing said clamping ring in said released position, said spring element, when being in said released position, protrudes beyond a contour of said sleeve thereby securing said clamping ring in said released position, said spring element, when being in said locking position, is disposed within the contour of said sleeve; wherein said clamping ring is biased into said locking position, and wherein said locking arrangement cooperates with said clamping ring and said sleeve so that said locking arrangement locks said clamping ring on said receiving connector, upon sliding said sleeve on said receiving connector axially until said locking position is reached; and wherein said clamping ring can be released from said locking position by moving said clamping ring axially against said bias.
