Abstract: A working component for mating with multiple shaft ends includes 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. The body portion has a work piece processing area for acting on the work piece to be processed and the clamping portion has a mounting hole with a longitudinal axis Y. The clamping portion includes a support portion and a mating portion which are overlapped along the direction of the longitudinal axis Y.

Abstract: An adaptor for adapting a working element to an end of a power tool shaft. The adaptor includes a central hole passing through the adaptor and has a longitudinal axis, a driving end facing the end of the shaft, and a tool end facing the working element and having a protruding portion, wherein the driving end is provided with grooves, the grooves and bosses formed between the grooves are alternately arranged around the circumference of the driving end, and the bosses have side faces each facing the central hole and located on a plane passing through an edge of a regular polygon and parallel with the longitudinal axis. The adaptor can thus be used to adapt different kinds of working elements to various kinds of driving shafts having different shapes of shaft end.

Abstract: A working tool adapted for use with an oscillating tool includes a hole defining a longitudinal axis and has a plurality of bulges which depart from the longitudinal axis by a radial distance. Each of the bulges has two flanks that extend inwardly towards the longitudinal axis and which are connected with each other at a recess portion that is formed between every adjacent two of the bulges. An arc portion of one of the bulges has a length which is unequal to a length of an arc portion of the other one of the bulges. By arranging bulges with unequal arc lengths in the hole of the working tool, the working tool can be mounted to different oscillating tools at multiple angles and, by decreasing the number of the bulges, contact between the bulges and an output shaft of the oscillating tool reduces wear and increases the service life of the output shaft.

Abstract: An oscillating power tool comprises a motor and an oscillating driving shaft driven by the motor. The driving shaft has a longitudinal axis and a free end. The free end has a flange. The flange of the free end has a securing section on one face. The securing section comprises at least two protrusions which are independent from each other. Each protrusion has at least three tips. As a result of this arrangement, a working tool may be fixed securely and reliably to the driving shaft of the oscillating power tool.

Abstract: An adapter for a multifunctional tool includes a converter with a first form-locating component mating with an output shaft end of the multifunctional tool and a fixer with a form-fit component mateable with the converter.
