Abstract

Disclosed is a retractable pen structure, including: a front pen barrel, a rear pen barrel, an inner barrel and an adjustment knob. The front and rear pen barrels are engaged to allow retractable movement along an axial direction. The inner barrel extends in and across the front and rear pen barrels and is able to slide forwards and backwards along the axial direction. A front section of the inner barrel is able to push a pen refill. A rear section of the inner barrel is provided with a radial engagement piece that has an outer end engaging with the adjustment knob. The adjustment knob is able to move forwards and backwards in a corresponding guide channel formed in the rear pen barrel or a pen clip and is able to be stopped in front and rear positioning notches in the guide channel. When one intends to store the pen, the adjustment knob is positioned in the rear positioning notch of the guide channel in the rear pen barrel so as to draw the pen refill into the front pen barrel, and to retract the front and rear pen barrels into a short-rod configuration. When one intends to use the pen, the adjustment knob is operated to disengage the engagement piece from the rear positioning notch and to expand the pen barrels into a long-rod configuration. The adjustment knob is then pushed to engage the engagement piece with the front positioning notch, and to cause the inner barrel to push the pen refill forwards thereby causing the pen tip to extend out of the front pen barrel and to be positioned in place. This invention allows easy operation of retraction and expanding the pen.
