| titleOfInvention | A two-color fountain pen |
| abstract | The utility model discloses a two-color fountain pen, which belongs to the technical field of stationery. Move the moving plate and the closing plug to the left until the through hole on the upper end of the moving plate is aligned with the through hole on the upper end of the connecting plate, and the liquid in the black ink bag can enter the hollow tube, and then the third connecting tube enters the pen tip In this way, the use of the black pen can be realized. When the blue ink sac needs to be used, the pen tip can be rinsed with water first, and then the moving plate in the second cavity can be pushed to make the liquid in the blue ink sac pass through the second connection. The tube enters the nib, and the blue pen can be used. When switching back and forth between the blue ink sac and the black ink sac, the nib should be rinsed with water before switching, so as to realize the use of a pen. The pen uses the effect of two colors. |
