Claims

[Scope of utility model registration request]

A tip consisting of a sliding body with a bottomed cylindrical shape and a locking flange on its outer periphery, which is slidably inserted from the tip of the barrel of a writing instrument, and a cylindrical body whose rear end is connected to the tip surface of the sliding body. A flange is provided on the outer periphery of the sliding body, into which an ink cylinder having a metal tip and a pen tip can be inserted and held, and which is slidably penetrated through the bottom of the sliding body from the rear end. a bottomed cylindrical rear shaft cylinder that is connected to the rear end of the shaft cylinder with its bottom facing backward; and a base that is inserted at the bottom into the rear shaft cylinder; A clip that is provided with a latch claw that protrudes retractably and whose tip is constantly pressed toward the outer periphery of the rear shaft cylinder is connected to the rear end of the actuating cylinder, and the actuating cylinder moves toward the tip. The flange of the actuating cylinder and the sliding body are formed by fitting a first coil spring around the tip of the actuating cylinder. A second coil spring is fitted near the rear end of the actuating cylinder to constantly press the actuating cylinder rearward against the elastic force of the first coil spring. A unique writing instrument with a pen tip.
