Abstract: A writing instrument with an adjustable shaft comprising a barrel, a grip and a head connected by threaded head to form a pen shaft, along with a switch for retrieving or retracting the pen point of the cartridge by clicking or turning a button, and a soft rubber gripping section covering the grip. A driver is installed under the switch inside the barrel, and a few support rods are put inside of the grip. When holders click the button to press the switch, the driver, in turn, pushes the top of the support rods, making the support rods prop the soft rubber gripping section into the shape of an ergonomic arch. When the button is clicked again, the shaft returns to the original shape of a cylinder.
