Patent Images
1. A touch-control writing tool, comprising:
- a pipe body with a hollow interior forming a long through hole, one end of which is penetrated by the long through hole to form an opening;
a rod body, whose one end is provided with a conductive writing head with a predetermined length and flexibility, the end of the rod body different from the writing head being inserted via the opening into the long through hole of the pipe body;
a rotating element coaxial with and pivotally installed in the pipe body and partly exposed from the opening of the pipe body, the writing head of the rod body extending via the rotating element to expose from the rotating element; and
a transmission component disposed in the long through hole of the pipe body and driven by the rotating element to drive the rod body to make an axial displacement in the long through hole, thereby adjusting the length of the writing head exposed from the rotating element.

Abstract
A touch-control writing tool wherein the pipe body of the touch-control writing tool has a long through hole and an opening on one end thereof. A rotating element is pivotally provided on the end of the opening of the pipe body. The writing head of a rod body goes through and protrudes from the rotating element. The rotating element drives the rod body to perform an axial displacement in the long through hole via the transmission component in the long through hole, thereby adjusting the length of the writing head outside the rotating element.
