摘要

The interface has shift lever elements longitudinally or pivotally arranged in a recess of a spindle head (20). The lever elements comprise drive elements for linking a tool holder (90). The tool holder comprises rear grip elements that are releasably engageable behind the drive elements of the lever elements by pivoting movement of the tool holder. The lever elements are designed as a ring-shape, and comprise two transverse bores. The spindle head is projected from a housing (10). A pin is fixedly arranged at the spindle head while another pin is movably arranged.
