[0013] 2. Closed type, characterized by at least one end of the channel being located on the surface of the writing sleeve, with the side surface of the filler all inside the channel.
[0014] 3. Hybrid type, which includes alternating open and closed types.
[0015] There are more options for channel selection, allowing users to choose freely according to their requirements to achieve the best user experience.
[0016] The preferred cross-sectional shape of the channel according to this utility model includes:
[0017] 1. Polygonal configurations, including regular polygons with n≥3 sides and star-shaped polygons.
[0018] 2. Curved configuration, including circles and / or at least a segment of an irregular shape formed by a curve and a straight line.
[0019] 3. The structure of written symbols, including the shapes of letters, numbers, or punctuation marks.
[0020] In a preferred embodiment of this invention, the cross-sectional shape of the filler is not exactly the same as the cross-sectional shape of the channel, and the two are adapted and fixed by gaps, anti-detachment parts or limiting protrusions.
[0021] As a preferred embodiment of this invention, different axial segments of the same channel may have different cross-sectional shapes, and the different cross-sectional segments are connected by a gradual transition or by direct connection of end faces.
[0022] As a preferred embodiment of this invention, the channel is provided with a limiting protrusion.
[0023] The preferred filler of this invention is provided with a manual replacement part.
[0024] As a preferred embodiment of this utility model, the upper sleeve is also provided with a tail cap.
