Claims

[Scope of utility model registration request]

A sharp pencil cartridge and a ballpoint pen cartridge have a hollow upper shaft and a hollow lower shaft that are removably connected, and are arranged vertically in parallel inside the shaft so that the lower tips of the cartridges can be drawn out alternately. In the writing instrument, the upper shaft has a partition wall that extends downward from the upper center and also serves as a slide track, and a partition wall that is provided on one side corresponding to the partition wall for feeding and centering operations of the sharp pencil cartridge. one window hole with a length that allows the ballpoint pen cartridge to be moved out, and the other window hole with a length that allows the ballpoint pen cartridge to be fed out on the other side; has an opening large enough to expose the cap of the sharp pencil cartridge and to lock the chuck from lowering, and to expose the cap of the ballpoint pen cartridge; Moreover, the lower end is fitted to the upper end of the sharp pencil cartridge, and the first
A first knob slides to lower the sharp pencil cartridge along the one window hole against the force of a spring; a second knob bar that slides to lower the ballpoint pen cartridge along the other window hole when operated, against the force of a second spring; , a first protrusion that slides along the track of the partition wall and falls toward the center of the upper shaft at the lower end of the track, and a mating first protrusion that falls outward from the center of the upper shaft; and a second protrusion that releases the depression by pressing on it.
