FIELD: machinery.
SUBSTANCE: invention relates to a quick-clamping device for mounting, in particular without the use of an auxiliary tool, of at least one working tool on a technological machine, such as a handheld tool, in particular on an angle grinder. A quick-clamping device for installing at least one working tool (10) on a technological machine (12) contains at least one output node (14) for telling the working tool (10) to move around the axis (16) of the output node (14) and at least at least one fastening unit (20) provided for at least axial fixation of the working tool (10) on the output unit (14) and containing at least one fastener (18) mounted movably on the output unit (14). At the same time, the quick-clamping device contains at least one safety assembly (22) containing at least one adjustable safety element (24) provided for protecting the fastener (18) installed relative to the outlet assembly (14) and movable at least around the axis (16) of the output node from movement around the axis (16) of the output node, and the safety element (24) provides fixation of the fastening element from movement around the axis (16) of the output node due to positive locking.
EFFECT: simplification of mounting of the working tool on the technological machine and/or dismantling of the working tool from the technological machine, thereby saving time, in particular when replacing the working tool and/or when activating the technological machine.
