Patent number: 7425948Abstract: A stylus for a portable apparatus is disclosed. The stylus is usable as a prop to support the portable apparatus to stand on a platform and comprises a main portion and a rotating portion. The main portion comprises a tip end and a pivot end, and at least one protruding rib is disposed on the pivot end. A positioning plate is disposed on one end of the rotating portion, and connects with the protruding rib. A bolt passes through the protruding rib and the positioning plate, so that the rotating portion could pivotably connect with the main portion. Furthermore, at least one positioning structure is formed on one end of the positioning plate. The cross-sectional shape of the positioning structure is an arc shape. The stylus further comprises an elastic component and a positioning ball.
