。[Claims for Utility Model Registration] The writing shaft 3 is inserted into the outer cylinder 2, and the notch portion 4 protruding from the rear end of the outer cylinder 2 is pulled in and clicked against the spring 5. The tip 6 of the writing shaft body 3 is pushed out from the tip of the outer cylinder 2 and held, and the notched part 4 is knocked again against the retraction spring 5, so that the tip 6 of the writing shaft 3 is pushed out by the spring force of the retraction spring 5. In a retractable double-knock writing instrument, a ratchet gear 8 is pivotally installed inside the outer cylinder 2 or within the lateral protrusion 7 of the outer cylinder 2 so that the tips of the teeth protrude into the outer cylinder 2, and each time the ratchet gear is clicked, First spring pawls 10 and 1 rotate the ratchet gear 8 a predetermined number of times each time.
A second spring claw 11 that engages with the ratchet gear 8 at the end of the second notching is provided on the writing shaft 3 or the notch portion 4 so that the claw tips thereof face each other, and a blocking claw 12 is provided to prevent the ratchet gear 8 from rotating in the opposite direction. The double-knock type writing instrument has teeth 8 having inclined tooth surfaces 13 so as not to engage with the second spring claw 11 every time the second knock is completed.
