Abstract

A personal digital mobile device stylus pen having its nib adjustable for its angle to buffer excessive force used to contact a touch monitor from a PDA or related product so to protect the touch monitor and to offer a touch angle that is most comfortable to its user as the stylus pen either bends or rotates when being subject to excessive force upon contacting the touch monitor characterized by a hollow nib cap is screwed in position at the end of the penholder to secure the nib having a ball at its rear end. Said nib cap contains a pad and a touch needle is screwed to the rear end of the nib cap to press the ball of the nib by the touch needle so that the nib only bends or rotates when being subject to a certain pressure to adjust its touching angle depending on the personal habit of holding a pen and to protect a PDA touch monitor from being damaged by excessive contact force from the nib which bends to offset such excessive force.
