Claims

[Claims for Utility Model Registration] (1) A core pipe 3 inserted into the outer cylinder 1 so as to be slidable in the axial direction, and a core pipe 3 disposed on the tip side of the core pipe 3, when the rear end of the core pipe 3 is clicked. After the lead chuck pieces 8 and 9 rotate forward in the direction of attaching the core, when the rear end notch is released, they rotate in the direction of releasing the core and move backward, and the lead chuck pieces 8 and 9 are attached in the direction of attaching the core. A sharp pencil comprising a first elastic body 10 for tightening the chuck. (2) The lead chuck pieces 8 and 9 are attached to the chuck holder 7 placed at the tip of the core pipe 3, and the lead chuck pieces 8 and 8 are attached to the arcuate surfaces 76 and 77 provided inside the chuck holder 7. , 9 are slidably aligned with each other, and the sharpening pencil according to claim 1, wherein the arcuate surfaces 80, 90 provided on the outside of the edges 80, 9 are slidably aligned with each other. (3) The combination of the outward engaging protrusions 82 and 92 integrally provided on the lead chuck pieces 8 and 9 and the inward engaging step 2c provided in the tip 2 of the outer cylinder 1 allows the lead S A sharpening pencil according to claim 1, characterized in that the sharpening pencil is adapted to send out. (4) The friction applying portion 12 is provided in a slider 11 that is arranged to be slidable in the axial direction in front of the lead chuck pieces 8 and 9 and is biased in the forward direction by the first elastic body 10. A sharpening pencil according to claim 1 of the utility model registration claim.
