Claims

[Scope of utility model registration request]

Outer sleeve 2 removably fitted into outer cylinder 1
an inner sleeve 4 that is slidably engaged with the outer sleeve 2; and a core delivery mechanism 5 that is installed inside the inner sleeve 4 and allows the core S to move forward but prevents it from retreating. , a slider 3 that is slidably disposed within the tip 2A located at the tip of the outer cylinder 1 and applies a predetermined frictional force to the lead S, and a biasing force stronger than the core biting force of the lead feeding mechanism 5. An elastic body 11 that urges the slider 3 forward, a stopper 6 that slidably engages the outer sleeve 2 and the inner sleeve 4, and a notch that urges the outer sleeve 2 and the inner sleeve 4 forward. A sharpening pencil comprising an elastic body 12 for a cushion.
