Claims

[Scope of utility model registration request]

After the pipe section retreats a minute distance from the most extreme position, the core clamp holder securely holds and grips the core, and as the pipe section moves forward, the core is similarly fed forward by the pipe section, until the pipe section reaches its maximum position. A set of sharp pencil mechanisms in which the pipe part and the lead holder are connected so that the lead holder does not hold or grasp the lead at all when in the tip position.
