Abstract
A pen with double pen tubes is provided. Pen tubes are symmetrically and slidably sheathed on a rack of a transmission mechanism. A press element is arranged on the rear end of the pen tube and is connected with a gear element of the transmission mechanism. The transmission mechanism comprises a rack, a gear element and a movable element. The gear element moves relatively to the rack side rim and tooth-shaped structure on the movable element, and the movable element and the refill connected on the lower end of the movable element are driven to move up and down through a rolling way converted from the translation. Refills are respectively disposed in two pen tubes and are connected with the movable elements of the transmission mechanism; an elastic element is sleeved on the protruding column on the top face of the rack; when the pen tube is pressed to move downward, the gear element rolls downward to drive the refill to move downward; when a stop part is clamped on a backstop part on the rack, a refill tip protrudes forwards and is positioned to be a writing state; when drawing the backstop part, the pen tube and the refill are driven to retract backwards through an elastic element, so that the pen tube moves upward and the refill is retracted to be a folding state; and the pen tube and the refill are synchronously extractable, thus enhancing the interest.
