[0027] Please refer to Figure 2 The telescopic assembly 5 includes a telescopic rod 501, a bracket 502, a handle 503, a gear 504 and a transmission seat 505. The first pen tip 3 is fixedly connected to one end of the telescopic rod 501, and the other end of the telescopic rod 501 is passed through the transmission seat 505 and connected to the liquid filling tank 8. The transmission seat 505 and the telescopic rod 501 are integrally formed;

[0028] A base 506 is installed on the inner wall of the first pen holder 1, and the bracket 502 is installed on the base 506. A rotating shaft is passed through the base 506, one end of the rotating shaft is connected to the gear 504, and the other end of the rotating shaft passes through the inner wall of the first pen holder 1 and is connected to the handle 503 on the outer wall of the first pen holder 1. The bottom end of the transmission seat 505 is provided with a rack meshing with the gear 504.

[0029] Please refer to Figure 2 A roller 508 is installed on the bracket 502, and a sliding groove 507 that cooperates with the roller 508 is provided on the top of the transmission seat 505.

[0030] Please refer to Figure 1 The telescopic rod 501 is a hollow round rod, and a pressure block 10 is fixedly penetrated at the other end of the telescopic rod 501. A piston 11 is provided on the liquid filling tank 8, and a needle tube 12 is provided on the piston 11 and penetrates the liquid filling tank 8. The central axis of the needle tube 12 is in a straight line with the central axis of the pressure block 10 and the telescopic rod 501.

[0031] The telescopic rod 501 of the present invention is a hollow round rod, one end of the telescopic rod 501 is connected to the first nib 3, and the other end of the telescopic rod 501 is passed through the transmission seat 505 and connected to the liquid filling tank 8, so the hollow round rod provides an infusion channel between the first nib 3 and the liquid filling tank 8; the other end of the telescopic rod 501 is fixedly passed through a pressure block 10, the needle tube 12 of the piston 11 on the liquid filling tank 8 matches the through hole on the pressure block 10, and during the entire process of the first nib 3 making telescopic movement in the first pen holder 1, the pillow of the needle tube 12 always remains in the telescopic rod 501.

[0032] The first pen tip 3 of the present invention only needs the medical staff to shake the handle 503 externally, and the handle 503 rotates to drive the gear 504 to rotate. The bottom end of the transmission seat 505 is provided with a rack meshing with the gear 504. The transmission seat 505 realizes telescopic movement in the front-to-back direction, thereby driving the telescopic rod 501 to do telescopic movement in the first pen holder 1, and the first pen tip 3 can realize the storage function; the roller 508 bears the radial force of the gear 504. This design avoids a long slide, is easy to assemble, and reduces the friction force of the telescopic rod 501 during the telescopic movement.

[0033] Please refer to Figure 1 The liquid adding box 8 is filled with absorbent sponge and medical ink, and a liquid adding port 801 and a liquid adding cover 802 are provided on the side wall of the liquid adding box 8.

[0034] The liquid filling box 8 of the present invention is filled with absorbent sponge and medical sterile ink. The squeezing force of the piston 11 by the pressing block 10 has the effect of squeezing the absorbent sponge, thereby squeezing the absorbent sponge. The ink in the absorbent sponge will be squeezed out through the injection needle 12 into the telescopic rod 501 and then transmitted to the first pen tip 3. This ink supply method avoids the phenomenon of large ink output and prevents ink from leaking into the first pen barrel 1.

[0035] Please refer to Figure 1 A support edge 13 is provided at the connection between the first pen holder 1 and the first pen tip 3, and a magnetic attraction portion 14 is embedded in the support edge 13. A magnetic attraction matching portion 15 is built into the end surface where the first pen cap 6 and the first pen holder 1 are connected. A conical connection portion 16 is provided on the first pen holder 1, and a connecting hole matching with the conical connection portion 16 is provided on the first pen cap 6. A plurality of evenly distributed reinforcing sheets 17 are embedded in the first pen cap 6.

[0036] The magnetic attraction portion 14 and the magnetic attraction matching portion 15 of the present invention can be made of magnetic sheets, and the magnetic attraction portion 14 and the magnetic attraction matching portion 15 can attract each other. When the first pen cap 6 is loose, it can be ensured that the first pen cap 6 will never fall off the first pen holder 1. The pen cap is made of elastic organic material, such as silica gel, etc. A conical connecting portion 16 is provided on the first pen holder 1, and the first pen cap 6 has a connecting hole that matches the conical connecting portion 16, so as to improve the connection strength between the first pen cap 6 and the first pen tip 3; the reinforcing sheet 17 is made of elastic metal and supports the first pen cap 6. The reinforcing sheet 17 can be inclined, and the inclination angle is equal to the angle of the conical surface of the conical connecting portion 16, so as to ensure that the inner wall of the connecting hole can be firmly buckled on the first pen tip 3, thereby ensuring the connection strength between the first pen holder 1 and the first pen cap 6.

[0037] Please refer to Figure 1 The first pen holder 1 is filled with an alcohol cotton layer 101 , and the outer contour of the alcohol cotton layer 101 is adapted to the first pen tip 3 .

[0038] The function of the alcohol cotton layer 101 of the present invention is that when it is in an emergency use environment, such as when medical staff perform surgery and must pay great attention to disinfection and protection, the pen tip of the marker pen also needs to be disinfected. Therefore, when using it, it is only necessary to cover the first pen cap 6 with this simple operation to achieve the disinfection and protection of the pen tip, which is simple and quick.

[0039] Please refer to Figure 1 A partition wall 18 is provided at the upper end of the liquid storage cavity 9, the second pen tip 4 is a fiber pen tip, the writing end of the fiber pen tip extends outward from the writing end of the second pen barrel 2, a contraction hole 19 is provided between the liquid storage cavity 9 and the writing end of the second pen barrel 2 to cooperate with the water guide end of the fiber pen tip, a liquid guide column 20 is provided in the liquid storage cavity 9, the liquid outlet end of the liquid guide column 20 is connected to the second pen tip 4, and the outer diameter of the liquid guide column 20 is smaller than the diameter of the contraction hole 19.

[0040] Please refer to Figure 1 The liquid storage chamber 9 is filled with medical alcohol.

[0041] The water-introducing end of the fiber pen tip of the present invention is tightly inserted into the contraction hole 19, and a round rod-shaped liquid-conducting column 20 is arranged in the liquid storage chamber 9. The outer diameter of the liquid-conducting column 20 is smaller than the diameter of the contraction hole 19. The gap between the liquid-conducting column 20 and the contraction hole 19 forms a channel for supplying medical alcohol. Under normal circumstances, the liquid-conducting column 20 is located in the contraction hole 19, and the channel is an annular channel.

[0042] Please refer to Figure 1A bushing 21 is provided in the connection portion between the second pen holder 2 and the second pen tip 4, the shrinkage hole 19 is opened in the bushing 21, and the outer wall shape of the bushing 21 matches the inner wall shape of the connection portion.

[0043] The size of the annular gap between the contraction hole 19 of the bushing 21 and the liquid-conducting column 20 determines the flow rate of the medical alcohol. In order to ensure a smooth supply of medical alcohol during use, it is necessary to ensure that the contraction hole 19 has a sufficient effective length. The effective length of the contraction hole 19 refers to the length of the contraction hole 19 above the fiber pen tip, that is, the remaining length after the fiber pen tip is inserted. Under the premise of ensuring that the contraction hole 19 has a sufficient effective length, the upper end surface of the bushing 21 is not higher than the lower end surface of the liquid storage chamber 9, so that all the alcohol used in it can be used up. Of course, in order to ensure that the contraction hole 19 has a sufficient effective length, the solution in which the upper end surface of the bushing 21 is higher than the lower end surface of the liquid storage chamber 9 of the pen barrel can also be adopted. The upper page of the side wall of the liquid storage chamber 9 can be provided with a liquid inlet and a cover.

[0044] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
