。[Detailed description of the invention] The present invention relates to a mechanical pencil broken lead remover in which a needle for removing a broken lead is attached to a short cylinder for inserting an eraser, and the embodiment shown in the figure is The short cylinder body 1 is removably fitted into the head of a shaft cylinder (not shown).
A short rod-shaped eraser 2 is fitted into the holder so that it cannot be inserted or removed, and a needle bed 3 is clamped between the inner surface of the circumferential wall of the short cylinder 1 and the outer circumferential surface of the eraser, and the upper end of the needle bed 3 is folded into a U-shape. The outer edge of the U-shaped bent portion 4 is bent into a concave shape, and the concave bent portion 5 is engaged with an outward flange 6 provided on the upper edge of the short cylindrical body 1.

がないなどの優れた効果を有するものである。Since the present invention is as shown above, it is extremely easy to attach the needle bed to the short cylinder, and it can be done securely.It is particularly effective because the needle bed is not used for erasers. In particular, the needle bed 3 is clamped between the inner surface of the peripheral wall of the short cylinder 1 and the outer peripheral surface of the eraser, and the upper end of the needle bed 3 is bent into a U-shape. The outer edge of the bent portion 4 is bent into a concave shape so that the concave bent portion 5 is engaged with the outward flange 6 provided on the upper edge of the short cylindrical body 1, thereby reducing the pushing force on the needle bed during use. The needle bed has excellent effects such as not being so-called retracted even when the needle bed is affected.

シャープペンシルの折損芯除去具。In a mechanical pencil whose lead is fed out by pushing the barrel section, a short barrel 1 is attached to the head of the barrel so that it can be inserted and removed freely, and a short bar-shaped eraser 2 cannot be inserted into or removed from the short barrel 1. At the same time, the needle bed 3 is inserted between the inner surface of the peripheral wall of the short cylinder 1 and the outer peripheral surface of the eraser, and the upper end of the needle bed 3 is bent into a U-shape. This tool for removing a broken lead of a mechanical pencil is made by bending the outer edge of the part 4 into a concave shape and locking the concave bent part to an outward flange 6 provided on the upper edge of the short cylinder 1.
