With the rapid development of capacitive solutions, interactive smart products with capacitive touch technology are also increasing. Capacitive touch has also evolved from the original finger touch to pen touch, especially for large-screen writing, capacitive pens have become an indispensable component.

[0003] For example, a Chinese patent discloses: a capacitive pen tip and a capacitive pen, CN217443834U, in which a conductive contact is fixed to the pen tip body by a fixed sleeve, and the fixed sleeve is detachably connected to the column. When replacing the conductive contact, only the fixed sleeve needs to be removed and the conductive contact can be pulled out. The structure is simple and the replacement is convenient.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the above structure can remove the fixing sleeve to pull out and replace the conductive contact, but the pen tip needs to be manually screwed to remove the fixing sleeve installed by threading. Since the pen tip usually has a smooth surface, it is easy to slip when screwing, resulting in inconvenience in replacement operation. Utility Model Content

[0023] The embodiment of the present application provides an active compatible passive capacitive pen, which effectively solves the problem that the conductive contact can be pulled out and replaced by removing the fixing sleeve of the above structure. However, when removing the fixing sleeve, the pen tip needs to be manually screwed to remove the fixing sleeve installed by threaded screwing. Since the pen tip usually has a smooth surface, it is easy to slip when screwing, resulting in inconvenience in replacement operation. When the pen tip needs to be replaced after long-term use, the first sleeve is pulled upward. During the sliding process of the first sleeve, the four rotating blocks are squeezed by the squeezing ring to rotate. The rotating blocks rotate to loosen the clamping and fixation of the pen tip. The old pen tip is removed, the new pen tip is taken out, and the new pen tip is inserted into the first sleeve. The first sleeve is loosened and the first sleeve is driven by the first spring to slide downward and reset. At this time, the four rotating blocks rotate and reset to clamp and fix the pen tip. During the operation, the replacement can be completed by only pulling the first sleeve. The operation is simple and convenient, which is conducive to improving the speed of replacement work.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application effectively solves the problem that the conductive contact can be pulled out and replaced by removing the fixing sleeve of the above-mentioned structure, but the pen head needs to be manually screwed when the fixing sleeve is removed. The fixing sleeve installed by screwing is removed. Since the pen head usually has a smooth surface, it is easy to slip when screwing, resulting in inconvenient replacement operation. The overall idea is as follows: it includes a pen body 11, the outer surface of the pen body 11 is slidably connected to the first sleeve 12, the first sleeve 12 is internally sleeved with the pen head 13, the inner surface of the first sleeve 12 is fixedly connected to the first spring 14, the inner surface of the first sleeve 12 is fixedly connected to the connecting ring 15, the connecting ring 15 is rotatably connected with four rotating blocks 16, and the inner surface of the first sleeve 12 is fixedly connected to the quick-change mechanism at one end close to the connecting ring 15. The quick-change mechanism includes an extrusion The pressure ring 17 and the extrusion ring 17 are fixedly connected to one end of the inner surface of the first sleeve 12 close to the connecting ring 15. When the pen tip 13 needs to be replaced after long-term use, the first sleeve 12 is pulled upward. During the sliding process of the first sleeve 12, the four rotating blocks 16 are squeezed and rotated by the extrusion ring 17. The rotating blocks 16 rotate to loosen the clamping and fixation of the pen tip 13, and the old pen tip 13 is removed, and the new pen tip 13 is taken out, and the new pen tip 13 is inserted into the first sleeve 12, and the first sleeve 12 is loosened. The first spring 14 drives the first sleeve 12 to slide downward and reset. At this time, the four rotating blocks 16 rotate and reset to clamp and fix the pen tip 13. During the operation, you only need to lift the first sleeve 12 to complete the replacement. The operation is simple and convenient, which is conducive to improving the speed of replacement work.

[0026] The pen tip 13 is sleeved on the outer surfaces of the four rotating blocks 16, and the four rotating blocks 16 are all on the same vertical line with the extrusion ring 17. A multifunctional control chip 18 is fixedly connected to the inside of the pen body 11, and a pressure sensor 19 is fixedly connected to one end of the pen body 11 close to the multifunctional control chip 18. When in use, the user holds the pen body 11 and interacts with the touch screen device through the first sleeve 12 to provide a more accurate and natural input experience. The pressure sensor 19 is used to detect the pressure of the pen tip 13 and transmit the pressure data to the multifunctional control chip 18. In the active mode, these data can be sent to the touch screen device to achieve different pen pressure effects and drawing accuracy. The multifunctional control chip 18 is responsible for managing various functions and mode switching, and switching between active and passive modes as needed to achieve active compatibility with passive effects.

[0027] Two slide grooves 21 are provided inside the pen body 11, and a second sleeve 22 is fixedly connected to the upper end of the first sleeve 12, and two second springs 23 are fixedly connected inside the second sleeve 22. One end of the two second springs 23 close to the slide groove 21 is fixedly connected to a limiting block 24, and the two limiting blocks 24 are slidably connected to the inside of the slide groove 21 respectively, and a pressing block 25 is fixedly connected to the upper end of the two limiting blocks 24. When the user holds the pen body 11 for daily use, the limiting block 24 is driven by the second spring 23 to slide into the slide groove 21 to limit the first sleeve 12 to prevent the first sleeve 12 from sliding due to accidental operation during daily use. When the first sleeve 12 needs to slide for replacement, the two pressing blocks 25 are pressed downward, and the pressing blocks 25 squeeze the second springs 23 downward and slide out of the slide groove 21. At this time, the first sleeve 12 can be lifted, which is conducive to improving the stability and reliability during use and provides better control.

[0028] In view of the problems existing in the prior art, the utility model provides an active compatible passive capacitive pen. When the pen tip 13 needs to be replaced after long-term use, the first sleeve 12 is pulled upwards. During the sliding process of the first sleeve 12, the four rotating blocks 16 are squeezed and rotated by the squeezing ring 17. The rotating blocks 16 rotate to loosen the clamping and fixation of the pen tip 13. The old pen tip 13 is removed, and the new pen tip 13 is taken out. The new pen tip 13 is inserted into the first sleeve 12, the first sleeve 12 is loosened, and the first sleeve 12 is driven by the first spring 14 to slide downward and reset. At this time, the four rotating blocks 16 rotate and reset to clamp and fix the pen tip 13. During the operation, only the first sleeve 12 needs to be lifted to complete the replacement. The operation is simple and convenient, which is conducive to improving the speed of replacement work.

[0029] Working principle:

[0030] The first step is that when using, the user holds the pen body 11 and interacts with the touch screen device through the first sleeve 12 to provide a more accurate and natural input experience. The pressure sensor 19 is used to detect the pressure of the pen tip 13 and transmit the pressure data to the multi-function control chip 18. In the active mode, these data can be sent to the touch screen device to achieve different pen pressure effects and drawing accuracy. The multi-function control chip 18 is responsible for managing various functions and mode switching, and switching between active and passive modes as needed to achieve active compatibility with passive effects. When the pen tip 13 needs to be replaced after long-term use , pull the first sleeve 12 upward, and during the sliding process of the first sleeve 12, the four rotating blocks 16 are squeezed and rotated by the squeezing ring 17. The rotating blocks 16 rotate to loosen the clamping and fixation of the pen tip 13, remove the old pen tip 13, take out the new pen tip 13, insert the new pen tip 13 into the first sleeve 12, loosen the first sleeve 12, and drive the first sleeve 12 to slide downward and reset through the first spring 14. At this time, the four rotating blocks 16 rotate and reset to clamp and fix the pen tip 13. During the operation, you only need to lift the first sleeve 12 to complete the replacement. The operation is simple and convenient, which is conducive to improving the speed of replacement work.

[0031] In the second step, when the user holds the pen body 11 for daily use, the second spring 23 drives the limit block 24 to slide into the slide groove 21 to limit the first sleeve 12 to prevent the first sleeve 12 from sliding due to accidental operation during daily use. When the first sleeve 12 needs to slide for replacement, the two pressing blocks 25 are pressed downward. The pressing blocks 25 squeeze the second spring 23 downward and slide out of the slide groove 21. At this time, the first sleeve 12 can be lifted, which is beneficial to improve the stability and reliability during use and provides better control.

[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
