[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-Figure 4 As shown, the pressure-sensing capacitive pen comprises a pen shell 1, a clamping block 11 is fixedly connected to the top of the left end of the pen shell 1, a protective cover 12 is threadedly connected to the top of the pen shell 1, a charging slot 13 is opened in the middle of the protective cover 12, a circuit board 15 is fixedly connected to the bottom of the inner cavity of the pen shell 1, a control mechanism 3 is fixedly connected to the bottom of the circuit board 15, an adjustment mechanism 2 is slidably connected to the inner wall of the pen shell 1, the adjustment mechanism 2 comprises a core unit 23, an outer wall of the core unit 23 is slidably connected to the bottom of the pen shell 1, and the control mechanism 3 comprises a fixed frame 31, and an outer wall of the fixed frame 31 is fixedly connected to the bottom of the circuit board 15.

[0027] By cooperating with the adjusting mechanism 2 and the controlling mechanism 3, the capacitive pen is adjusted so that the lines drawn by the capacitive pen can be thick or thin.

[0028] like Figure 2 As shown, a slot 14 is provided at the bottom of the front end of the pen housing 1 , and an adjusting rod 21 is slidably connected to the inner wall of the slot 14 .

[0029] By toggling the adjusting rod 21, the outer wall of the adjusting rod 21 slides on the inner wall of the card slot 14. When the adjusting rod 21 moves to a suitable position, the outer wall of the adjusting rod 21 engages with the inner wall of the card slot 14, thereby fixing the refill unit 23 so that the refill unit 23 will not expand or contract during subsequent use. This keeps the pressure on the pressure sensor 33 unchanged, ensuring stability during use. At the same time, it can also avoid the phenomenon of unstable current in the refill unit 23 and avoid broken lines, thereby increasing stability.

[0031] When the battery 17 needs to be replaced, the protective cover 12 is screwed out so that the outer wall of the protective cover 12 is no longer threadedly connected to the top of the pen housing 1, and then the battery 17 can be taken out for replacement.

[0032] like Figure 3 , Figure 4 As shown, an adjusting block 22 is fixedly connected to the bottom of the core unit 23, a front end of the adjusting block 22 is fixedly connected to the rear end of the adjusting rod 21, an outer wall of the adjusting block 22 is slidably connected to the bottom of the pen case 1, and a moving block 24 is fixedly connected to the bottom of the core unit 23, an outer wall of the moving block 24 is slidably connected to the bottom of the pen case 1.

[0033] When the adjusting rod 21 is turned, the adjusting block 22 is driven to move synchronously, the adjusting block 22 drives the core unit 23 to move synchronously, the core unit 23 drives the moving block 24 to slide synchronously in the inner cavity of the pen shell 1, and the core unit 23 is limited and guided by the adjusting block 22 and the moving block 24, so that the adjusting block 22 will not deviate when moving.

[0034] like Figure 3 , Figure 4As shown, the bottoms of the left and right ends of the inner cavity of the fixed frame 31 are fixedly connected with connecting blocks 32, the top of the inner cavity of the fixed frame 31 is fixedly connected with a pressure sensor 33, the top of the pressure sensor 33 is electrically connected to the inner wall of the circuit board 15, the bottom of the pressure sensor 33 is fixedly connected with a conductive spring 34, the bottom of the conductive spring 34 is fixedly connected with a conductive slider 37, the outer wall of the conductive slider 37 is slidably connected to the inner cavity of the fixed frame 31, the outer wall of the conductive slider 37 is rotatably connected to the top of the refill unit 23, and the refill unit 23, the conductive slider 37, the pressure sensor 33 and the circuit board 15 are electrically connected.

[0035] The pressure is transmitted to the pressure sensor 33 through the conductive spring 34 and the spring 36. The pressure sensor 33 controls the magnitude of the electricity conducted by the circuit board 15 according to the magnitude of the pressure, thereby changing the thickness of the line drawn by the pen core unit 23, thereby achieving the effect of changing the thickness of the line drawn by the pen core unit 23.

[0036] like Figure 3-Figure 5 As shown, the left and right parts of the conductive slider 37 are slidably connected with a guide rod 35, the outer wall of the guide rod 35 is movably sleeved with the inner wall of the connecting block 32, the outer wall of the guide rod 35 is movably sleeved with a spring 36, the bottom end of the spring 36 is fixedly connected to the top end of the conductive slider 37, and the top ends of the guide rod 35 and the spring 36 are fixedly connected to the bottom end of the pressure sensor 33.

[0037] When the refill unit 23 moves, it drives the conductive slider 37 to move upward, so that the inner wall of the conductive slider 37 slides on the outer wall of the guide rod 35, and at the same time, the outer wall of the conductive slider 37 slides on the inner wall of the fixed frame 31. The conductive slider 37 is guided by the guide rod 35, so that the conductive slider 37 slides more smoothly. At the same time, the conductive slider 37 drives the conductive spring 34 and the spring 36 to contract synchronously.

[0038] The working principle of the utility model is as follows: when in use, the capacitive pen is adjusted according to the needs of the user, and the adjusting rod 21 is toggled so that the outer wall of the adjusting rod 21 slides upward on the inner wall of the card slot 14, and at the same time, the adjusting rod 21 drives the adjusting block 22 to move synchronously, and the adjusting block 22 drives the pen core unit 23 to move synchronously, and the pen core unit 23 drives the moving block 24 to slide synchronously in the inner cavity of the pen shell 1, and the adjusting block 22 and the moving block 24 limit and guide the pen core unit 23, so that the pen core unit 23 will not deviate when moving, thereby making the pen core unit 23 drive the conductive slider 37 to move upward, so that the inner wall of the conductive slider 37 slides on the outer wall of the guide rod 35, and at the same time, the outer wall of the conductive slider 37 slides on the inner wall of the fixed frame 31, and the conductive slider 37 is guided by the guide rod 35, so that the conductive slider 37 slides more smoothly, and at the same time, the conductive slider 37 drives the conductive spring 34 and the spring 36 to contract synchronously, and the conductive spring 34 and the spring 36 transmit the pressure to the pressure The sensor 33, the pressure sensor 33 controls the size of the electricity conducted by the circuit board 15 according to the size of the pressure, thereby changing the thickness of the line drawn by the pen core unit 23, which has the effect of changing the thickness of the line drawn by the pen core unit 23. When the adjusting rod 21 is moved to the appropriate position, it is pushed to the right so that the outer wall of the adjusting rod 21 is engaged with the inner wall of the card slot 14, thereby fixing the pen core unit 23, so that the pen core unit 23 will not be extended or retracted during subsequent use, thereby keeping the pressure on the pressure sensor 33 unchanged, ensuring stability during use, and also avoiding the phenomenon of unstable current in the pen core unit 23, avoiding broken lines, and having the effect of increasing stability. When charging is needed later, it is charged by the charging slot 13. When the battery 17 needs to be replaced, the protective cover 12 is unscrewed so that the outer wall of the protective cover 12 is no longer connected to the top thread of the pen shell 1, and then the battery 17 can be taken out for replacement, thereby greatly improving the user experience.
