Claims

[Scope of utility model registration request]

An inner cylinder 4 having a base 3 at its tip is housed in the tip shaft 1 by biasing a return spring 8 between the tip shaft 1 and the tip shaft 1 so that it can be integrally moved in the axial direction with respect to the tip shaft 1 in the rotational direction. A cam slope 20 is provided at the rear end of the inner cylinder 4, and a cap 2 integrally provided with a cam slope 30 facing and in contact with the cam slope 20 is rotatably inserted into the rear end hole of the front shaft 1 and is prevented from coming off. At the same time, when the cap 2 is rotated with respect to the front shaft 1 and the cam slopes are slid together so that the tip of the cam slope 30 is located at the rear end of the cam slope 20, the cap 3 is moved from the tip of the front shaft 1. protrudes, and a cam slope 30 is attached to the rear end of the cam slope 20.
When the bottom of the tip shaft 1 is positioned, the base 3 is configured to be housed in the tip barrel 1, and there is an outer window hole 7 in the vicinity of the gripping fingertip of the tip barrel 1 and a portion corresponding to the outer window hole 7 of the inner cylinder 4. An inner window hole 24 is provided in each of the inner cylinder 4, and a core case 17, a relay pipe 16, and a 30% chuck 9 are installed in the inner cylinder 4.
A fastener 10 is provided on the outside of the 3-split chuck 9 protruding from the inside of the inner cylinder 4 and inside the base 3, and the 3-split chuck 9 is housed in the inner cylinder 4 in the distal direction. A slider 12 is provided which is moved to the center and returned to its original state by a core feeding spring 11, and a side knob button 25 is provided in the outer window hole 7 to push the upper end inclined surface 14 of the slider 12 downward. A side-knot type sharpening pencil characterized by the fact that the number 9 can be moved in the direction of the tip.
