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 is provided with a plurality of projections which extend in a radial direction vertical to the longitudinal axis (Y) and which are distributed alternately, wherein at least one of the shaft ends is selected from the group consisting 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, and the plurality of grooves are connected with the mounting hole, 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:
a first lateral surface extended outwards radially from the longitudinal axis;a second lateral surface extended outwards radially from the longitudinal axis; anda third lateral surface connected to the first lateral surface and the second lateral surface,wherein each of the first lateral surface, the second lateral surface, and the third lateral surface are all parallel to the longitudinal axis (Y),wherein the third lateral surface of two adjacent plurality of projections are located at the circumferential edge of the positioning hole, andwherein the first lateral surface and the second lateral surface each define an upstanding wall of one of the plurality of grooves; and 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. |
