Apparently, the described embodiments are partial embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figures 1-6 , an ophthalmic surgery special marking pen, comprising a pen shaft 1, one end of the pen shaft 1 is fixedly installed with a sleeve 2, one end of the sleeve 2 is provided with a fixed plate 3, the top of the fixed plate 3 is provided with a horizontal and oblique stroke structure 4, the horizontal and oblique stroke structure 4 includes a horizontal part and an oblique part, which are used to form the top of the "left" or "right" character mark. A sliding groove 5 is opened at a position corresponding to the inner side of the fixed plate 3 end face and the horizontal and oblique stroke structure 4, and the sliding groove 5 includes a square hole part 501 and a round hole part 502. The square hole part 501 is communicated with the round hole part 502, and the square hole part 501 is opened on the side of the fixed plate 3 facing the outside, while the round hole part 502 is opened on the side of the fixed plate 3 facing the inside of the sleeve 2;

[0028] A T-shaped sliding plate is slidably connected inside the square hole part 501. The T-shaped sliding plate includes two first horizontal pressing plates 7 and a first vertical rod 8. The first vertical rod 8 is separated from the first horizontal pressing plate 7. The first horizontal pressing plate 7 is slidably connected to the side wall of the square hole part 501, and a positioning spring is arranged at the connection. One end of the first vertical rod 8 facing the inside of the sleeve 2 is provided with a first vertical rod structure 10. The T-shaped sliding plate is jointly composed of the first vertical rod 8 and the first horizontal pressing plate 7, and together with the horizontal and oblique stroke structure 4 forms a "left" character mark. First positioning plates 801 are arranged at both ends of the first vertical rod 8, and first linkage grooves 701 are opened at positions corresponding to the positions of the two first horizontal pressing plates 7 and the first positioning plates 801, so that when the first vertical rod 8 is pushed by the first vertical rod structure 10 to extend out of the square hole part 501, the two first horizontal pressing plates 7 can be driven by the first vertical rod 8 to move and be flush with the marking surface of the horizontal and oblique stroke structure 4 to form a "left" character structure;

[0029] On the two hole walls of the square hole portion 501 adjacent to the two first transverse pressing plates 7, second vertical rods 9 are slidably arranged. The second vertical rods 9 and the two first transverse pressing plates 7 together form a square shape, and together with the horizontal and diagonal structure 4, form a "right" shape structure. At the ends of the two second vertical rods 9 facing the inside of the sleeve 2, a second vertical rod structure 11 is arranged. At both ends of the two second vertical rods 9, support grooves 901 are provided, and the support grooves 901 correspond to both ends of the first transverse pressing plate 7. When the end faces of the second vertical rods 9 and the first transverse pressing plate 7 are flush with each other, the end portions of the first transverse pressing plate 7 are located within the support grooves 901. When the two second vertical rods 9 are pushed out of the square hole portion 501 by the second vertical rod structure 11, the two first transverse pressing plates 7 move synchronously and are flush with the top surface of the horizontal and diagonal structure 4 to form a "right" shape structure. In summary, this marking pen can perform "left" or "right" shape markings at the same end, effectively improving the convenience of the marking pen during use. Moreover, the marking surfaces of the horizontal and diagonal structure 4, the first transverse pressing plate 7, the second vertical rod 9, and the first vertical rod 8 are all roughened, which can retain the ink for a long time to facilitate multiple embossings and effectively avoid frequent plugging and unplugging of the pen cap.

The axis of the sliding rod 1001 and the axis of the round hole portion 502 are on the same straight line. The bottom end of the sliding rod 1001 is fixedly connected to the first vertical rod 8. Therefore, when the sliding rod 1001 moves downward, it can push the first vertical rod 8 downward. Furthermore, through the first positioning blocks provided at both ends of the first vertical rod 8 and in cooperation with the first linkage groove 701, the first transverse pressing plate 7 can effectively follow the first vertical rod 8 downward. A first arc-shaped pushing plate 1003 is fixedly connected to the side wall of the sliding rod 1001. The top end of the first arc-shaped pushing plate 1003 is fixedly connected to the inner end wall of the sleeve 2. Since an ejection groove 12 corresponding to the position of the first arc-shaped pushing plate 1003 is provided on the barrel wall of the sleeve 2, and the arc portion of the first arc-shaped pushing plate 1003 extends out of the sleeve 2 through the ejection groove 12, when the first arc-shaped pushing plate 1003 is pressed toward the inside of the sleeve 2, the effect of pushing the sliding rod 1001 downward can be achieved.

[0031] The second vertical rod structure 11 includes a sliding ring 1101. The outer wall of the sliding ring 1101 fits and is slidably connected to the inner wall of the circular hole portion 502. An extension plate 1102 is provided at the top of the sliding ring 1101. The bottom end of the sliding ring 1101 is fixedly connected to two second vertical rods 9. The extension plate 1102 is arc-shaped, and the arc surface of the extension plate 1102 can fit with the inner wall of the circular hole portion 502. Therefore, when the extension plate 1102 moves downward, the circular hole portion 502 can provide good stability for the movement of the extension plate 1102. A second arc-shaped push plate 1103 is provided on the outer wall of the extension plate 1102, and the arc portion of the second arc-shaped push plate 1103 extends out of the sleeve 2 through another pop-up groove 12. At the same time, the top end of the second arc-shaped push plate 1103 is fixedly connected to the top wall of the sleeve 2. Therefore, when the second arc-shaped push plate 1103 is pressed downward, the purpose of pushing the sliding rod 1001 downward can be achieved;

[0032] And the arc portions of the first arc-shaped push plate 1003 and the second arc-shaped push plate 1103 are respectively engraved with left and right marks for respectively corresponding to the protrusions in the shape of "work" character and "mouth" character;

[0033] An ink chamber 601 is provided inside the pen cap 6. The pen cap 6 is used to protect the horizontal and oblique structure 4 and each part forming the "work" character and "mouth" character. And an infiltration sponge 602 communicating with the magic chamber is provided on the inner end wall of the pen cap 6. When the pen cap 6 is completely sleeved on the outer wall of the sleeve 2, the inner wall of the pen cap 6 will press both the first arc-shaped push plate 1003 and the second arc-shaped push plate 1103 into the inside of the sleeve 2. While improving the fixing strength of the pen cap 6 through the elastic force of the first arc-shaped push plate 1003 and the second arc-shaped push plate 1103, each part forming the "work" character and "mouth" character extends out and is inserted into the inside of the infiltration sponge 602 to improve the clarity of the marking when the marker pen is in use.

[0034] Compared with the prior art, this device uses the first vertical rod structure 10 and the second vertical rod structure 11 to respectively push out protrusions of different shapes to cooperate with the horizontal and oblique structure 4 to respectively form the "left" character or "right" character marks, so that both ends of the marker pen can make "left" or "right" character marks, which can effectively improve the convenience of the marker pen in use.

[0035] It should be understood that for those of ordinary skill in the art, modifications or variations can be made according to the above description, and all such modifications and variations should fall within the protection scope of the appended claims of the present utility model.
