Abstract
The body (2) of the tool-holder (1) is equipped with spherical caps (14, 15, 16) which come to rest against the flat inside faces (6, 7, 8) of a trirectangular trihedron in the tool-mounting base. Flanges (17, 18) guide conical-tipped retaining pins (21, 22) in apertures (20, 21). These tips fit into conical recesses (23, 24). The rod (13) of a jack mounted on the base spreads the pins apart, and while entering the recesses, the pins exert on the tool-holder a force capable of immobilizing it and acting along a predetermined line of action.
