A pressing device for a pen having a spring, a center stick engaging the spring and a nib part. The pressing device comprises a penholder having a guide slot, a movable tube having an outwardly projecting engaging piece that extends through the guide slot, a bounce device, a press or push cap, and a clipping part. The clipping part has a pen clip provided with a clamping piece that engages the engaging piece when the nib part is extended outwardly from the penholder in a writting position. When the pen is being attached to an article such as a pocket, the clamping piece will touch the article such that the pen clip is urged to move outward. As a result, the clamping piece will disengage the engaging piece. The engaging piece will move upward along the guide slot causing the spring to be stretched pressing the center stick upward such that the nib part will be received in the penholder.
