WORKING TOOL FOR MANUAL MACHINE Russian patent published in 2021 - IPC B27B5/32 B23D61/02 B24B45/00 B24D5/16 B23B51/04 

FIELD: woodworking industry.

SUBSTANCE: group of inventions relates to woodworking industry, in particular to saws. A connecting device has a clamping foot that partially restricts a recess in the radial direction passing from the axis of rotation of a tool. The clamping foot in the direction radial relatively to the axis of rotation of the tool is limited by the first boundary edge located on the first, minimum, boundary circle passing around the axis of rotation of the tool. The clamping foot passes along the plane orthogonal to the axis of rotation of the tool. The clamping foot is asymmetric relatively to any plane of symmetry defined by the radial and axial directions determined by the axis of rotation of the tool, in particular, it does not have mirror symmetry. The connecting device has a mounting coding element belonging to the working tool, provided for interaction with the coding element available on a holder that ensures correct installation when the working tool is installed on the holder. The mounting coding element belonging to the working tool is located on the clamping foot of the connecting device and is made in the form of a recess that completely passes through the maximum thickness of the material of the clamping foot.

EFFECT: design of the working tool is simplified.
