As shown in fig. 1-3, a double-ended pen comprises a pen holder 1, a pen clip 2, an oil tube 3, a fixing ring 4, a tail plug 5, a limiting column 6, a pen core 7, a partition plate 8, a guide sliding piece 9, a sealing piece seat 10 and a sealing piece 11. The pen clip 2 is connected to the pen holder 1 and used for fixing the pen holder 1 on other articles; the oil pipe 3 is divided into a thin pipe end 31 and a thick pipe end 32 which are sleeved in the penholder 1 to provide ink for the double-ended pen; the partition plate 8 and the two pen cores 7 form a double-pen-head assembly, and the partition plate 8 is clamped between the two pen cores 7; the pen core 7 comprises a cotton core 71 and a pen point 72, and the cotton core 71 is wrapped outside the pen core 7 and is arranged in the oil pipe 3; the pen point 72 is positioned at two sides of the clapboard 8, and the sliding guide piece 9 is positioned in the pen holder 1 and sleeved on the oil pipe 3.

Specifically, the partition plate 8 is divided into a lower partition portion 81, a middle partition portion 82, and an upper partition portion 83 as shown in fig. 6 to 7; wherein the middle partition 82 and the upper partition 83 divide the cotton core 71 into two parts, each of which is impregnated with a fluorescent pigment of a different color in advance; the middle partition 82 and the upper partition 83 are built in the thick tube end 32 of the oil tube 3 together with the cotton core 71; the cross-sectional area of the middle partition 82 is larger than that of the upper partition 83 because the cotton core 71 mainly absorbs ink at the position corresponding to the middle partition 82, so that the cotton core can be completely separated in color without mutual influence. The lower partition 81 is used for partitioning the pen point 72, and the cross section of the lower partition 81 is smaller than that of the middle partition 82 as the pen point 72 is thinner relative to the cotton core 71; the cross sections of different parts of the partition plate 8 are different, so that the weight of the pen body can be reduced, and the thickness of the pen holder 1 can not be additionally increased.

The pen point 72 is specifically a fluorescent pen point commonly used in the prior art which is divided into two symmetrical pen points 72, each pen point 72 has a plurality of sections, the pen point is rectangular, and the sides and the corners of the rectangle can be used for writing, so that lines with different thicknesses are obtained. The side of each pen point 72 is provided with a rectangular section, and a user can realize the drawing of thicker lines by inclining the pen holder 1.

For the oil pipe 3, as shown in fig. 8, on the side close to the thin pipe end 31, the thick pipe end 32 is further provided with symmetrically distributed stop strips 34; the thick pipe end 32 is also provided with convex strips 321 which are symmetrically distributed; on the side far from the thin tube end 31, the thick tube end 32 is externally sleeved with a fixing ring 4, and a protruding ring 33 is arranged at the intersection of the fixing ring 4 and the thick tube end 32 and used for preventing the fixing ring 4 from sliding downwards. The fixing groove 4 is provided with a limiting column 6, and the limiting column 6 is matched with the pen clip 2 for use and used for preventing the double-ended pen from moving upwards in the using process. The upper part of the thick pipe end 32 is connected with a tail plug 5.

As shown in fig. 4-5, the slide guide 9 is specifically provided with first guide slots 91 symmetrically distributed on the body of the slide guide 9, and the protruding strip 321 can slide in the first guide slots 91; a sealing element seat 10 and a sealing element 11 are sleeved in the sliding guide piece 9, two clamping blocks 111 are symmetrically arranged on the sealing element 11, and a clamping groove 101 matched with the clamping blocks 111 for use is arranged on the sealing element seat 10. The inner side of the pen holder 1 is provided with a limiting position (not shown in the figure) for limiting the sealing element seat 10 and the sealing element 11 so as to fix the sealing element seat in the pen holder 1. The guide slide member 9 is provided with two second guide grooves 92, and the seal seat 10 is further provided with a baffle plate 102, the baffle plate can slide in the second guide grooves 92, and the baffle plate 102 is rotatably connected with the seal seat 10 and is used for sealing the pen head 72 when the highlighter is folded.

Also included in this embodiment is a spring (not shown) that is sleeved over the thin tube end 31, with one end abutting the thick tube end 32 and the other end abutting the upper end of the seal 11.

During use of the double-ended pen of the present embodiment: the tail plug 5 is pressed, the spring is compressed, the oil pipe 3 and the guide sliding piece 9 move downwards together, the guide sliding piece 9 is abutted against the pen holder 1, the baffle plate 102 slides in the second guide groove 92, and the pen head 72 extends out of the sealing piece seat 10; the tail plug 5 is continuously pressed, the convex strip 321 slides in the first guide groove 91, the pen head 72, the pen core 7, the partition plate 8 and the cotton core 71 are fixed together, the limiting column 6 reaches a positioning block (not shown) in the pen clip 2, the pen head 72 extends out of the pen holder 1 and is fixed, and writing can be carried out after the tail plug 5 is loosened. After the pen is used, the tail plug 5 or the raised pen clip 2 can be pressed again, so that the limiting column 6 is separated from the positioning block in the pen point 2; under the action of the spring force, the slide guide 9 and the oil pipe 3 move upwards, the pen point 72 retracts into the sealing element seat 10, and the baffle plate 102 is closed. The design of the baffle 102 is to avoid drying the nib 72, and further avoid the evaporation of moisture in the cotton core 71, thereby increasing the service life of the highlighter.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
