WORKING TOOL FOR A HAND-HELD MACHINE Russian patent published in 2022 - IPC B27B5/32 B23D61/02 B24D5/16 

FIELD: machine tools.

SUBSTANCE: group of inventions relates to a working tool for processing a workpiece, made for installation on a hand-held machine. Working tool comprises a attachment means configured to be connected detachably to the output shaft of the hand-held machine, attached to the holder so that the axis of the output shaft and the axis of rotation of the working tool are substantially aligned, and made with a recess. The attachment means has at least one clamping foot limiting the recess at least partially in the radial direction extending from the axis of rotation of the tool. The clamping foot in the direction substantially radial relative to the axis of rotation of the tool is limited by a first boundary edge located on the first boundary circumference extending around the axis of rotation of the tool. The clamping foot extends at least substantially along a plane orthogonal to the axis of rotation of the tool. The clamping foot is made in the form of an elastic foot and is designed to connect the working tool and the holder so that the working tool at least partially perceives the loads acting in the axial direction aligned with the axis of rotation of the tool due to elastic deformation or elastic bending.

EFFECT: working tool can be replaced quickly.
