Please refer to fig. 1 to 7. It should be understood that the structures, ratios, sizes, and the like shown in the drawings are only used for matching the disclosure of the present disclosure, and are not used for limiting the conditions of the present disclosure, so that the present disclosure is not limited to the technical essence, and any modifications of the structures, changes of the ratios, or adjustments of the sizes, can still fall within the scope of the present disclosure without affecting the function and the achievable purpose of the present disclosure. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

As shown in fig. 1 to 7, the present invention provides a writing brush, which is characterized in that the writing brush comprises a brush head 1, a brush casing 2, a first brush core 3, a second brush core 4 and an ink pushing rod 5, wherein the brush casing 2, the first brush core 3 and the second brush core 4 are all hollow tubular structures, and the first brush core 3 and the second brush core 4 are sequentially arranged in the brush casing 2.

The pen point 1 is detachably connected to one end of the pen shell 2, and the root of the pen hair of the pen point 1 is inserted into one end of the first pen core 3. One end of the second pen core 4 is provided with an ink filling head 41, and the ink filling head 41 is arranged in the other end of the first pen core 3. One end of the ink pushing rod 5 is provided with a piston 51, and the piston 51 is arranged at the other end of the second pen core 4. The outer surface of the other end of the pen shell 2 is provided with a limiting opening 21, the outer surface of the second pen core 4 is provided with a limiting buckle 42, and the second pen core 4 is clamped into the limiting opening 21 through the limiting buckle 42 and is limited and fixed in the pen shell 2.

The pen shell 2 is internally provided with 2 clamping grooves 24, the outer surface of the first pen core 3 is provided with 2 first clamping strips 31, and the outer surface of the second pen core 4 is provided with 2 second clamping strips 44. The first pen core 3 is clamped into the clamping groove 24 through the first clamping strip 31 and connected to the pen shell 2, and the second pen core 4 is clamped into the clamping groove 24 through the second clamping strip 44 and connected to the pen shell 2.

A rubber tube 6 is connected between the ink injection head 41 of the second pen core 4 and the other end of the first pen core 3, and the rubber tube 6 plays a role in sealing, so that ink cannot leak outwards when being added.

An O-ring 7 is arranged between the pen point 1 and one end of the first pen core 3, an O-ring groove is formed in one end of the pen point 1, an O-ring groove is formed in one end of the first pen core 3, and the O-ring 7 is arranged in the O-ring groove. The O-ring 7 plays a role in sealing after the pen point 1 is connected with the first pen core 3, so that ink cannot leak.

The outer surface of the other end of the pen shell 2 is provided with a pen clip 22, one end of the pen clip 22 is provided with a clip 23, and the clip 23 is correspondingly positioned above the limiting opening 21. When the pen clip 22 is pressed by hand, the clip 23 touches the limit buckle 42 in the limit opening 21, so that the second pen core 4 can draw the ink from the pen shell 2.

The pressing ring 43 is arranged at the other end of the second pen refill 4, and when the second pen refill 4 is arranged in the pen shell 2, the pressing ring 43 is pushed by a hand, so that the second pen refill 4 can be more easily pushed into the pen shell 2.

The one end of nib 1 is equipped with the external screw thread, and the one end of pen shell 2 is equipped with the internal thread, and nib 1 is connected in the one end of pen shell 2 through external screw thread and internal screw thread cooperation. The pen point 1 can be repeatedly replaced through the external thread of the pen point 1 and the internal thread of the pen shell 2.

When using the writing brush, the second refill 4 is taken out of the pen case 2 by pressing the pen clip 22 with a hand, and the ink pushing rod 5 is pulled by a hand to suck ink from the ink filling head 41 into the second refill 4. Then the second pen core 4 is loaded into the pen shell 2, the ink pushing rod 5 is slowly pushed by hand to control the dosage of the ink, the ink enters the first pen core 3 and contacts with the root of the pen hair of the pen point 1, and the pen hair in the pen point 1 contains the ink to write. When the pen point 1 is damaged for a long time, the pen point 1 is unscrewed by hand to be separated from the pen shell 2, and then the pen point 1 is replaced.

In summary, the writing brush of the invention has the advantages that the brush head can be detached and replaced through the ingenious design; the pen shell can store ink, and the output dosage of the ink is easier to control. Therefore, the present invention effectively overcomes various disadvantages of the prior art and has high industrial utilization value.
