Handwriting pen

Abstract

A handwriting pen is disclosed. The handwriting pen comprises of a pen barrel 12 and a pen tip 11 which is arranged at one end of the pen barrel 12. A slit 121 is opened on the pen barrel 12. A rotatable rotation element 13 is mounted in the slit 121 through a rotation shaft 14. An enlarged head portion 131, with thickness larger than the width of the slit 121, is on one end of the rotation element 131. When using the handwriting pen, the user rotates the rotation element 13 to make the enlarged head portion 131 of the rotation element rotate 13 into the slit 121 on the pen barrel 12. Since the thickness of the head portion 131 is larger than the width of the slit 121, the slit 121 will be pried open by the head portion 131, and the diameter of the pen barrel 12 is thus increased. The user can hold the pen barrel 12 at the bulged place where the diameter is larger; therefore the handwriting pen can be held and handled more easily. Additionally, the rotation shaft 14 mounted on the pen barrel 12 at the other extremity to the pen tip 11. After the rotation element 13 is rotated, the longer end of the rotation element 13 will extend out a considerable distance from the slit 121 and lengthen the entire length of the handwriting pen. With the length of the handwriting pen is increased, handling and maneuvering of the handwriting pen is made easier.
