Claims

[Scope of utility model registration request]

By rotating the rear shaft forward and backward relative to the front shaft, the refill of the knock-type mechanical pencil housed there moves back and forth, and when moving forward, the tip of the refill protrudes from the opening at the tip of the front shaft, making it possible to write. A mechanical pencil that retracts into the front shaft when reversing has a knock button that is fitted into the rear end opening of the rear shaft so that it can be knocked, and a cylindrical clutch that is connected to the knock button so that it can be displaced at right angles to the axial direction. The clutch is equipped with a cylindrical displacement pawl that elastically protrudes from the outer circumferential surface of the clutch and is biased so that it comes into contact with the inner circumferential surface of the rear shaft and is displaced perpendicularly to the axial direction to be eccentric. Equipped with a clutch pendulum of When moving forward, the rear end moves out of the clutch pendulum, causing the clutch to be displaced perpendicular to the axial direction and become eccentric, causing a portion of the front edge of the clutch to fit into the rear end opening of the core case inside the refill. A mechanical pencil with a rotating retractable mechanical pencil that can be tapped by facing the lead cap.
