The compression sleeve is arranged in the limiting cavity, and the length of the limiting cavity is consistent with the maximum length of the compression sleeve, so that the compression sleeve can move linearly to a certain extent. The end of the penholder 1 is provided with a penholder protruding locking snap ring 3.

The other end of the compression sleeve 14 is arranged around the hollow cylinder 10, one end of the pen tongue 12 is arranged in the middle of the hollow cylinder 10, and ink enters the ink suction and storage device through the pen tongue 10. A gap is arranged between the compression spring 16 and the compression sleeve 14, and two ends of the stainless steel spring 16 respectively lean against the plane inner wall of the compression sleeve 14 connected with the compression rod 15 and the hollow cylinder 10.

The penholder 1 is connected with the pen holder 4, the ink absorption and storage device provided with the hollow cylinder 10 is inserted into the pen holder 4, and the inner wall of the hollow cylinder 10 is tightly sleeved with the outer wall of the circular interface tube protruding from the pen holder 4. The pen tongue 12 is inserted into the middle round hole of the pen holder 4, no gap is arranged between the pen tongue 12 and the pen holder 4, an ink channel is arranged on the pen tongue 12, and ink slowly reaches the pen point 13 along the pen tongue.

One end of a hollow cylinder 10 of the ink absorbing and storing device forms a thick opening end, the inner circular wall of the port of the ink absorbing and storing device is tightly extruded with the outer circular wall of the hollow cylinder 10, and the ink absorbing and storing device is adhered by glue. The compression sleeve 14 may be a polyethylene compression sleeve, which is cylindrical and has a flange around it.

The compression sleeve 14 and the compression rod 15 are integrated, the stainless steel spring 16 is placed inside the ink suction and storage device 14, a gap is formed between the outer edge of the spring 16 and the inner edge of the compression sleeve 14, and two ends of the spring 16 are respectively close to the inner wall of a plane where the ink suction and storage device is connected with the compression rod 15 and the hollow cylinder 10.

The circular inner wall of the thick open end of the ink absorption and storage container 14 and the circular outer wall of the hollow cylinder 10 are tightly pressed together and bonded with glue so that they can withstand the repulsive force when the spring 16 is pressed, while preventing ink from leaking out therefrom.

As shown in figure 2, the ink sucking and storing device 14 with the hollow cylinder 10 is inserted into the pen holder 4, the inner wall of the hollow cylinder 10 is tightly sleeved with the outer wall of the circular mouthpiece protruding from the middle part of the pen holder 4, so that ink is prevented from leaking from the inner wall of the hollow cylinder 10, and the ink sucking and storing device 14 can be taken down at any time for cleaning.

The pen tongue 12 and the pen point 13 are combined and then inserted into the middle round hole of the pen holder 4, and no gap is arranged between the pen tongue 12 and the pen holder 4. The tongue 12 is provided with an ink channel, and the ink slowly reaches the pen point 13 along the tongue 12, so that the writing purpose is realized.

The penholder 1 and the pen holder 4 are screwed together through the thread openings on the upper surfaces of the penholder and the pen holder, as shown in fig. 3, the functions of protecting the ink absorption and storage device and facilitating the holding of the pen are achieved.

The pen cap 8 and the pen holder 4 are tightly sleeved on the pen holder 4 through a protruding locking snap ring, as shown in fig. 4, so that the aim of sealing and protecting the pen point 13 is fulfilled. When the pen cap is used, the pen cap 8 is taken down and sleeved on the tail of the pen holder 1, and the protruding locking snap ring in the pen cap 8 is tightly clamped on the protruding locking snap ring of the pen holder 1, as shown in fig. 5, so that the pen cap 8 is prevented from being lost and the comfort level of holding a pen is increased.

In the present embodiment, the stainless steel spring 16 is in the compressed position by pressing the pressing rod 15, and the compression sleeve 14 compresses the space by reducing the folding angle of the edge, thereby exhausting the air inside. When the pressure lever 15 is released, the elastic force of the spring 16 is released, and the elastic force acts to expand the ink sucking and storing device 14, and simultaneously the spring 16 acts as a plastic folding hose supporting the compression sleeve 14 to prevent the plastic folding hose from being randomly contracted and deformed, so that negative pressure is formed in the air inside. The ink now travels along the tongue 12 and into the ink reservoir 14. Thus, the ink suction is conveniently and rapidly completed; after the ink is sucked, the ink can not be directly leaked out because the ink has a certain surface tension and is adsorbed at the pen tongue, so that the ink can be stored in a large quantity.

The shape of the cap 8 of the present embodiment matches the shape of the pen holder 4 and the pen point 7, and the clip 7 is provided outside the cap 8. The stainless steel spring 16 is made of 304 stainless steel wire, the nib 7 is made of stainless steel material, and the remaining components are made of various types of plastic materials, as in the prior art.
