<p>A tool holder for a rotary and/or chisel hammer is provided with a sleeve body (20) with a central opening for receiving a tool bit (10) with a least one axial locking groove (11) which is closed at both ends for engaging a cylindrical locking body (50) which is located in a through opening (22) in the sleeve body. The sleeve body (20) is surrounded by a displaceable adjustment sleeve (30) which has an area for preventing an outward radial movement of the locking body and which in a displaced position permits the radial outward movement of the at least one locking body (50). A ring element consisting of several ring segments (41) is located behind the locking body and extends with a support portion (42) into the through opening. With the movement of the locking body it can be displaced to the rear against spring pressure and in its displaced position permits a radially outward movement of the at least one locking body. <IMAGE></p> |
