The outer cylinder of the writing tool and stylus, and the writing tool and stylus equipped with this outer cylinder

摘要

PROBLEM TO BE SOLVED: To provide a case where the outer shape of a writing tool and a stylus is deformed in order to achieve both ease of use and portability, and the operation required for the deformation is simpler. SOLUTION: This is an outer cylinder that supports the outer shape of a rod-shaped writing tool and stylus, has a hexagonal cross section when used, and can be deformed into a flat foldable shape when carried. It is equipped with a connector for supporting the stylus from four directions, and when a force is applied so that the upper and lower stylus pieces are sandwiched between the fingers from the hexagonal cross section at the time of use, the left and right stylus pieces are folded and carried. Become a shape. In addition, it is an outer cylinder that opens the left and right cylinder pieces that were folded when a force is applied from both sides to the hinge portions that correspond to the left and right corners from the shape when carried.
