Abstract

The utility model discloses a roly-poly pen. The roly-poly pen comprises a pen barrel and a refill. The pen barrel comprises a large head end and a small head end; the end surface of the large head end is arc-shaped; and the gravity center of the whole pen is in the space included by the arc-shaped surface. The large head end and the small head end are in threaded connection or connected in a blocking manner. The end surface of the large head end is made of a soft rubber material. The refill is one of a pencil, a ballpoint pen or a pen. The gravity center of the pen is in the large head end. The fundamental principle of the roly-poly pen is based on the roly-poly principle so that the roly-poly pen is convenient to place and is prevented from falling and breaking; the outer surface of the large head end is covered by a layer of TPE (Thermoplastic Polyurethane Elastomer)) material which has the function of anti-skidding and assisting in turning over books; and the large head end can be rotatably rotated or unplugged so that the refill in the pen barrel is convenient to replace.
