The tongue 2 is arranged on the side with the stylus nib 1, corresponding to a writing surface with the stylus nib 1, and serves as an ink guide (or ink-containing, moisturizing). The water reservoir 3 is located between the pen tongue 2 and the gallbladder 5. And it communicates with them, and it has the functions of anti-leakage and ink-conducting. The water reservoir 3 and the pen tongue 2 can be made into one body, or it can be a split structure water reservoir 3 which can have an integrated or separate connection to the pen mouth. Or a water-conducting device in the pen, such as one or two water-conducting cores 1 1 or 1 1 ′, etc., where the water-conducting tube 1 Γ also plays the role of sucking ink and exhausting: a nib with a seam 1, a tongue 2 and the water reservoir 3 are assembled together by the pen item 4, the pen tongue 2 and the pen item 4 can also be made into one body; the pen item 4 is wrapped in part or all of the water reservoir 3, part or all of the pen tongue 2 and part of the pen tip 1 The outside, so that people hold the pen free of ink pollution when writing; Pen item 4 can also be made into one with the pen holder 6, pen holder 6 can also be made into one with the pen 5 to simplify the structure.

 The fountain pen with elastic device of the present invention includes a stylus pen tip 1, a pen tongue 2, a water reservoir 3, a pen item 4, a pen sleeve 5, a pen holder 6, a pen cap 7, and the like. Referring to FIG. 2, an elastic device 8 is provided in the pen tongue 2 and the water reservoir 3. The elastic device 8 can be embedded in the outer side of the pen tongue 2 or can be installed in the water reservoir 3 and installed on the pen item 4 and the pen tongue 2. Between the water reservoir 3, due to the elastic force of the elastic device 8 acting on the pen tongue 2, the pen tongue 2 is tightly abutted to the nib 1-side, so that the pen tongue 2 and the nib 1 fit.

 Referring to FIG. 1 and FIG. 3, a pen tip 2 ′ is also provided on the other side of the stylus tip 1, which corresponds to the other writing surface of the stylus tip 1. This structure with double pen tips is generally applied to both sides of the thick and thin head. A writing fountain pen can ensure sufficient water supply on each writing surface when writing on both sides. The pen tongue on one side can be provided without a sink, and the tongue without a sink can moisturize the pen tip. Of course, in order to make the water supply sufficient, In general, the pen tongues on both sides are equipped with a sink.

 The nib with a seam can be made into a sheet shape or a round rod shape, and there is a water-guiding slit from the tip of the nib to the middle of the nib body.

For double-sided writing fountain pens with a thick and thin tip on both sides of the nib, the shape of the open section of the nib is generally flat, so that the nib elasticity is uniform when the book is thick and thin, and the feel is good when writing The writing surface on both sides of the pen tip is a circular arc surface a, a small arc surface b, see FIG. 12; the longitudinal projection shape of the slit of the nib 1 tip can be wedge-shaped, such as "V" or trapezoidal, etc. See Figure 13, 14, 15; The wide-edge opening of the wedge-shaped slit corresponds to the large arc surface a of the thick writing surface, and the narrow-edge opening of the wedge-shaped slit corresponds to the small arc surface b of the thin writing surface. This can ensure that wedge-shaped slits are used when writing thick typefaces. The larger side has more water, and the font appears thicker; the smaller wedge-shaped seam has less water, and the font is thinner, so that the best effect of coarse and fine division can be achieved with a fountain pen on both sides.-Slit nib 1 can be in pen item 4 On the center line of the double-tongue solution, the same smooth writing effect is achieved when writing in both directions, see Figure 1.
