Claims

[Claims for Utility Model Registration] (1) A large number of cores having a certain length and a pointed tip are housed in a straight line arrangement, and the tip has a two-arc claw that can grip the rear end of the first core. A core tube constituting a chuck; a hollow outer tube inserted so that the core tube, with the core held by the chuck, can be fitted into the tip opening from the tip end and can also be advanced a certain length; In the outer barrel dispensing pencil, the inner circumferential portion of the outer barrel near the tip opening protrudes at one point with a small diameter to form a step, and the wall surface of the core tube has a fixed length extending along the axis following the chuck root. The groove is extended, and a coil spring is interposed between the step of the core tube and the outer tube to force it to move backward at all times. After that, stretch the tip straight and bend it in the shape of an "o" toward the center to create a relief part, and then bend it diagonally toward the center to create a tension part. The pencil is provided with a protruding part formed of a slightly curved hook part, and the dispensing pencil is attached so that the protruding part protrudes into the core tube from the split groove. (2) The feeding pencil according to claim 1, wherein the protruding portion is formed separately from the coil spring and is joined to the coil spring via a spacer. (3) The feeding pencil according to claim 2, wherein the protruding portion and the spacer are integrally formed of a resin material.
