The invention is a dual-drive, self-ratcheting multiple input ports mechanism, that converts oscillatory motion applied to its input, to unidirectional axial rotation motion at its output and is able to be switched to produce solely clockwise rotation at its output, regardless of the direction of rotation applied to the input and is able to be switched to produce solely counterclockwise rotation at its output, regardless of the direction of rotation applied to the input and is provided with a detachable input handle, that can be coupled to said multiple input ports.
