Abstract (en)
[origin: WO2018072997A1] The invention relates to a quick clamping device for a portable machine tool, in particular an angle grinder, comprising at least one output shaft (12a; 12b) that can be rotatably driven and that has at least one clamping unit (16a; 16b) which, for the purpose of fixing an insert bit (18a) to the output shaft (12a; 12b) without using tools, comprises at least one movably mounted clamping element (20a, 22a; 20b, 22b) for applying a clamping force to the insert bit (18a) in a clamping position of the clamping element (20a, 22a; 20b, 22b), and further has at least one operating unit (24a; 24b) for moving the clamping element (20a, 22a; 20b, 22b) into the clamping position and/or into a release position of the clamping element (20a, 22a; 20b, 22b), in which release position the insert bit (18a) can be removed from the clamping unit (16a; 16b) and/or the output shaft (12a; 12b). According to the invention, the quick clamping device comprises at least one securing unit (26a; 26b), in particular a self-locking unit and/or a detent unit, which is designed to prevent a movement of the clamping element (20a, 22a; 20b, 22b) from the clamping position into the release position of the clamping element (20a, 22a, 20b, 22b) at least under the action of a force decoupled from the control unit (24a; 24b) and acting on the clamping element (20a, 22a; 20b, 22b) in the direction of the release position of the clamping element (20a, 22a; 20b, 22b).
