As shown in fig. 5, 6 and 8, the two sliding blocks 8 are symmetrically arranged, the sliding blocks 8 can slide in the first sliding groove or the second sliding groove, when the sliding blocks 8 are in the first sliding groove, the intermediate assembly 5 is located at the first position, the user squeezes the pen point 3 at this time, the second tip 7 can pierce the second sealing plate 4, when the user squeezes the sliding blocks 8 from the inside of the first sliding groove to the inside of the second sliding groove, the intermediate assembly 5 is located at the second position, the user squeezes the pen point 3 at this time, the first tip 6 pierces the first sealing plate 2, and in addition, the depth of the second sliding groove is the depth of the pen point 3 entering the ink tube 1.

In another embodiment of the present invention, further, a plurality of ink-spreading holes are formed on both the upper surface of the first connecting plate 502 and the upper surface of the second connecting plate 503. As shown in fig. 8 and 9, the first connecting plate 502 and the second connecting plate 503 are provided with fine ink-scattering holes, the connecting post 501, the first tip 6 and the second tip 7 are not provided with ink-scattering holes, and the ink-scattering holes are arranged so that the ink in the ink tube 1 can flow through the ink-scattering holes after the pen head 3 is mounted on the ink tube 1 and reach the position of the pen head 3.

In still another embodiment of the present invention, the first pointed end 6 and the second pointed end 7 are both conical structures. As shown in fig. 4, 8 and 9, the conical structure facilitates the first tip 6 to pierce the first sealing plate 2, the conical structure facilitates the second tip 7 to pierce the second sealing plate 4, and a plurality of smaller cones may be provided to directly tear the first sealing plate 2 or the second sealing plate 4 when the pen tip 3 is squeezed.

In another embodiment of the present invention, the pen tip 3 further includes a pen tip body 301, a retaining ring 302 with a circular ring structure is fixedly connected to the periphery of the pen tip body 301, and a plurality of bumps 9 are fixedly connected to the periphery of the retaining ring 302 along a circumferential array. As shown in fig. 4 and 7, the stop ring 302 can limit the depth of the nib body 301 entering the ink tube, so as to prevent the nib body 301 from entering the ink tube too deeply, thereby playing a role of limiting, and the protrusion 9 is fixed for the user to rotate the nib 3, so that the nib 3 can enter the ink tube 1 or leave the ink tube 1 more easily.

In another embodiment of the present invention, the top of the pen head body 301 is fixedly connected with a plurality of positioning posts 10, and the middle assembly 5 is provided with a plurality of positioning holes corresponding to the positioning posts 10. Referring to fig. 7 and 9, the positioning posts 10 are fixedly connected to the top of the pen head body 301 along a circumferential array, the positioning holes are formed in the lower surface of the second connecting plate 503 along the circumferential array, the positioning holes are matched with the positioning posts 10, the number of the positioning posts 10 is consistent with the number of the positioning holes, the number of the positioning posts 10 is greater than 1 and less than 9, the number of the positioning posts 10 is less, the positioning effect cannot be achieved, the number of the positioning posts 10 is greater, and time is wasted, a user inserts the positioning posts 10 into the positioning holes when inserting the pen head 3 into the ink tube 1, the positioning posts 10 play a role in positioning the pen head 3, after the positioning posts 10 are inserted into the positioning holes, the intermediate assembly 5 rotates along with the rotation of the pen head 3, and thus the slider 8 can move from the first sliding groove to the second sliding groove, and the intermediate assembly 5 is switched from the first position to the second position.

In still another embodiment provided by the present invention, further, the inside of the ink tube 1 is filled with ink, the ink is a lower alcohol suspension, and one end of the ink tube 1 is provided with a lithium-based grease for plugging the lower alcohol suspension. In this embodiment, the lower alcohol suspension is used as ink, the lithium-based grease is used as a blocking agent, and the solvent is easily volatilized when the lower alcohol suspension is exposed to dry air for a long time, so that the ink becomes sticky and cannot be written normally, and the blocking agent is used for blocking to avoid evaporation of the lower alcohol suspension; in addition, low-carbon alcohol suspension with low viscosity flows backwards in the ink tube 1, the lithium-based ester also has the effect of stopping ink from flowing backwards, the lithium-based ester and the low-carbon alcohol suspension are not mutually soluble, the interface is clear, the turbidity phenomenon does not occur, air bubbles in the ink tube 1 are easy to centrifugally remove after a pen is filled, the lithium-based ester is mostly polysiloxane substances, is not mutually soluble with water, is oily, has good high and low temperature stability, is not frozen at-20 ℃, does not overflow and evaporate at 80 ℃, has strong fluidity, and can still keep good moisture retention and sealing under the condition that the temperature of the neutral pen is greatly changed by the lithium-based ester, so that the low-carbon alcohol suspension is prevented from evaporating or flowing backwards and overflowing; during fast writing, the lithium-based ester can follow up at any time, the wall hanging is light until the ink is completely written, so that when the ink is selected, the inside of the ink tube 1 is shown as figure 10, and low-carbon alcohol suspension and lithium-based ester are arranged in the ink tube.

In still another embodiment of the present invention, further, the ink tube 1 is filled with ink, and the ink is ink. The ink is a viscous oil prepared by adding oil smoke and the like into linseed oil, synthetic pine nut oil (mainly containing terpene alcohols), mineral oil (oil obtained by fractionating minerals such as petroleum) and ebonite, and is selected without filling lithium-based ester, and because the ink is a difficult volatile substance, thickening or drying of the ink caused by solvent volatilization basically does not exist, the interior of an ink tube 1 is shown in figure 11 when the ink is selected, and only the ink is contained in the ink tube.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
