When the fixed cover is rotated, the push plate is reset to press against the bracket under the action of the elastic force of the first spring, thereby increasing the friction between the second buckle and the pen shell. The installation and disassembly of the bracket are completed by rotating the fixed cover, thereby reducing the difficulty of maintenance and improving the efficiency of maintenance.

Then reinstall the nib cap. The second spring on the side of the pen case will apply pressure to the carbon fiber nib to ensure the fit between the carbon fiber nib and the nib cap. When in use, it will also provide writing feedback to the user. Through the material properties of the carbon fiber nib, the service life of the carbon fiber nib is increased.

[0022] The embodiment of the present application effectively solves the technical problem of the above-mentioned capacitive stylus that the shell is difficult to disassemble when a fault occurs, which increases the difficulty of maintenance and the maintenance cost. When a fault occurs and maintenance is required, the fixed cover is rotated. When the fixed cover is rotated to the extreme position, the second buckle is separated from the restraint of the pen shell, and the fixed cover is pulled to pull out the bracket to pull out the battery and the mainboard for maintenance. When the maintenance is completed, the bracket is inserted into the pen shell again, the second buckle is aligned with the notch at the side end of the pen shell and inserted, and the fixed cover is rotated again to make the second buckle clamp the pen shell. In this process, the bracket will press against the push plate after entering the pen shell, so that it overcomes the elastic force of the first spring and slides. When the fixed cover is rotated, the push plate is reset to press against the bracket under the action of the elastic force of the first spring, increasing the friction between the second buckle and the pen shell. Friction, the installation and disassembly of the bracket is completed by rotating the fixed cover, which reduces the difficulty of maintenance and improves the efficiency of maintenance. The carbon fiber nib is made of a highly conductive material with excellent comprehensive performance and has many unparalleled advantages over other materials. In addition to high conductivity, it is also corrosion-resistant, wear-resistant, high-temperature resistant, high-strength, and light-weight. When it needs to be replaced after a long period of use, rotate the nib cover to release the first buckle from the pen shell, pull out the nib cover, and then pull out the old carbon fiber nib to replace the new one. After reinstalling the nib cover, the second spring on the side of the pen shell will apply pressure to the carbon fiber nib to ensure the fit between the carbon fiber nib and the nib cover. When in use, it will also provide writing feedback to the user. Through the material properties of the carbon fiber nib, the service life of the carbon fiber nib is increased.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the shell of the capacitive stylus is difficult to disassemble when a fault occurs, which increases the difficulty of maintenance and the maintenance cost. The overall idea is as follows:

[0025] In view of the problems existing in the prior art, the utility model provides a capacitive pen with a conductive carbon fiber material nib, comprising a pen shell 1, a nib cover 2 is installed on the side end of the pen shell 1, a bracket 4 is slidably installed inside the pen shell 1, a fixed cover 3 is rotatably installed on the side end of the bracket 4, a second spring 9 is fixedly installed on the side end of the pen shell 1, and a first buckle 12 is fixedly installed on the side end of the nib cover 2.

[0026] A second buckle 13 is fixedly installed on the side end of the fixed cover 3, a carbon fiber nib 11 is installed inside the nib cover 2, a push plate 8 is slidably installed inside the pen shell 1, a first spring 7 is fixedly installed on the side end of the push plate 8, and a main board 5 is fixedly installed inside the bracket 4.

[0027] A battery 6 is fixedly installed inside the bracket 4; the main board 5 is connected to the battery 6 through a wire, a magnetic sheet 14 is fixedly installed on the side end of the pen shell 1, and four electrode columns 15 are fixedly installed on the side end of the pen shell 1; the electrode columns 15 are connected to the main board 5 through a wire.

[0028] Working principle:

[0029] The first step is, when a fault occurs and maintenance is required, rotate the fixed cover 3. When the fixed cover 3 is rotated to the extreme position, the second buckle 13 is separated from the restraint of the pen shell 1. The fixed cover 3 is pulled to pull out the bracket 4 to pull out the battery 6 and the main board 5 for maintenance. When the maintenance is completed, the bracket 4 is inserted into the pen shell 1 again, and the second buckle 13 is aligned with the notch at the side end of the pen shell 1 and inserted, and the fixed cover 3 is rotated again to make the second buckle 13 clamp the pen shell 1. During this process, the bracket 4 will resist the push plate 8 after entering the pen shell 1, so that it can overcome the elastic force of the first spring 7 and slide. When the fixed cover 3 is rotated, the push plate 8 is reset to resist the bracket 4 under the action of the elastic force of the first spring 7, increasing the friction between the second buckle 13 and the pen shell 1. The installation and disassembly of the bracket 4 is completed by rotating the fixed cover 3, thereby achieving the effect of reducing the difficulty of maintenance and improving the maintenance efficiency.

[0030] Second step, the carbon fiber pen tip 11 is made of a highly conductive material with excellent comprehensive performance and has many advantages that are incomparable to other materials. In addition to high conductivity, it also has the characteristics of corrosion resistance, wear resistance, high temperature resistance, high strength, and light weight. When it needs to be replaced after long-term use, rotate the pen tip cover 2 to disengage the first buckle 12 from the restraint of the pen case 1, pull out the pen tip cover 2, then extract the old carbon fiber pen tip 11 and replace it with a new one, and then install and reset the pen tip cover 2. The second spring 9 on the side of the pen case 1 will apply pressure to the carbon fiber pen tip 11 to ensure the fit between the carbon fiber pen tip 11 and the pen tip cover 2, and will also provide writing feedback to the user during use. Through the material characteristics of the carbon fiber pen tip 11, the effect of extending the service life of the carbon fiber pen tip 11 is achieved.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
