Abstract (en)
[origin: EP0521259A1] To drive a tool (12), a portable power tool has a hollow spindle (14) to which the tool (12) can be fastened between two flanges (16, 18). The outer flange (16) is formed on the end of a clamping bolt (22) which is inserted through a central opening (17) of the tool (12) and projects with its other end from the housing (42). The clamping bolt (22) can be secured to this end by means of a locking element (20) in such a way as to locked against rotation. A clamping device (24) is provided for actuation. The clamping device (24) can be moved against the force of spring elements (26) between a clamping position in which the locking element (20) is acted upon in the axial direction for clamping the tool (12) and a release position in which the tool is relieved for the manual change-over. The spring elements (26) are arranged between an axial fixed stop (28) and an axially displaceable stop. <IMAGE>
