Abstract:
1. A working component for mating with multiple shaft ends of multiple tools, comprising: a body portion; and a clamping portion which is connected to the body portion and suitable for mounting the working component to the shaft ends, wherein the body portion has a work piece processing area for acting on a work piece to be processed, the clamping portion has a mounting hole with a longitudinal axis (Y), and the clamping portion includes a support portion and a mating portion which are overlapped along the direction of the longitudinal axis (Y), wherein at least one of the shaft ends is at least one of a polygon projection, four T-like shaped projections, or a plurality of projections arranged on a circle concentric to the longitudinal axis (Y), and the mating portion is provided with a positioning hole, which has the same longitudinal axis (Y) as the mounting hole and a plurality of grooves configured as extending outwards radially from the circumferential edge of the positioning hole so as to form a plurality of projections, wherein the positioning hole is a regular polygon having a plurality of equilateral sides and the plurality of grooves are connected with the mounting hole, and the grooves are engaged to the shaft end having four T-like shaped projections, when the working component mating with the shaft end having four T-like shaped projections; the grooves are engaged to the shaft end having a plurality of projections arranged on a circle concentric to the longitudinal axis (Y), when the working component mating with the shaft end having a plurality of projections arranged on a circle concentric to the longitudinal axis (Y); each of the plurality of projections comprises: the positioning hole is engaged to the shaft end having a polygon projection, when the working component mating with the shaft end having a polygon projection.
