Initially, the design of the talking pen mainly focused on how to accurately read the coded information printed on books or cards through optical recognition technology and convert it into voice output to help children better learn basic knowledge such as language and mathematics. However, as the market's demand for the functionality and user experience of the talking pen continues to rise, the design of the talking pen has gradually evolved from a single information reading device to a multifunctional integrated device. For example, modern talking pens not only need to have precise optical recognition capabilities, but also need to consider ergonomics, durability, and ease of use, among other aspects. In particular, the design of the pen tip is one of the key areas of research and development, as it directly affects the accuracy of the reading and the user's experience.
[0003] Although the talking pen in the prior art has made significant progress in many aspects, there are still deficiencies in the replaceability and stability of the pen tip module. Traditional talking pens usually adopt an integrated pen tip design, which, although ensures a certain stability and durability, means that the entire talking pen needs to be repaired or replaced once the pen tip is damaged, increasing the cost of use. At the same time, when users try to replace the pen tip themselves, they often encounter problems such as complex operation and unstable installation, affecting the convenience and experience of use, so we propose a replaceable pen tip module structure for a talking pen.

[0030] The fixing frame device 7 comprises a first circular plate 73 and a second circular plate 74, one side of the first circular plate 73 is fixedly connected with two rectangular plates 72, the rectangular plates 72 and the interior of the connecting ring 76 are provided with wires, the wires are electrically connected with the insertion needle 9 made of metal, and the upper portion of the rectangular plate 72 is provided with a terminal post, which is not shown in the figure.
[0031] The connecting ring 76 is arranged between the two rectangular plates 72 and fixedly connected with the two rectangular plates 72, and the connecting ring 76 is provided with internal threads.
[0032] The central part of the first circular plate 73 is provided with a through hole, and one end of the spring 77 is fixedly connected with the first circular plate 73.
[0033] The first circular plate 73 is fixedly connected with the moving plate 75, and the moving plate 75 is provided with a threaded hole 71.
[0034] The second circular plate 74 is provided with a rectangular opening 78 for the moving plate 75 to penetrate, and the second circular plate 74 is fixedly connected with the front shell 4.
[0035] The insertion needle 9 is provided with external threads 91, and the interior of the front shell 4 is fixedly connected with a limiting block 42.
[0036] The interior of the front shell 4 is fixedly connected with a connecting plate 43, and the connecting plate 43 is fixedly connected with a rubber ring 44.
[0037] The pen tip part 8 is provided with a first step part 82, and the first step part 82 is fixedly connected with a second step part 81.
[0038] The outer side of the front shell 4 is bonded with a silica gel anti-skid layer 41, one end of the front shell 4 is fixedly connected with a threaded connecting part 2, the bowl-shaped structure 5 is provided with a decorative ring 3 and a groove part 6.
[0039] Working principle: when the pen tip needs to be installed or replaced, the user first unscrews the bolt 10, which connects the moving plate 75 with the front shell 4 together. After unscrewing the bolt 10, the spring 77 fixed on the first circular plate 73 will push the pin 9 and the pen tip part 8 outwards due to the loss of external pressure, so that the pen tip part 8 is pulled out from the bowl structure 5 and the front shell 4 together with the pin 9. At this time, the user can rotate the pen tip part 8, and then easily remove the old pen tip and install a new pen tip. The new pen tip is connected through the external thread 91 on the pin 9 and the internal thread 91 in the connecting ring 76.
[0040] In order to ensure the stability of the pen tip part 8 during use, the pin 9 is not only connected with the connecting ring 76 through the thread, but also a rubber ring 44 is arranged inside the front shell 4 for the pin 9 to pass through, which plays a clamping role. This double fixing mechanism effectively prevents the pen tip from loosening during use. In addition, the pen tip part 8 is provided with a first step part 82 and a second step part 81, which increases the friction and facilitates rotation during disassembly.
[0041] The fixing frame device 7 includes a first circular plate 73 and a second circular plate 74, wherein the first circular plate 73 is connected with the connecting ring 76 through two rectangular plates 72. Such design not only ensures the strength of the structure, but also provides enough space for the spring 77 to move smoothly. When the pen tip needs to be replaced, the spring 77 can smoothly push the pen tip part 8 out, avoiding the risk of damage caused by forced disassembly. At the same time, the second circular plate 74 is provided with a rectangular opening 78 for the moving plate 75 to pass through, which makes the moving plate 75 can move freely inside the front shell 4 after disassembly, so as to realize more flexible operation.
[0042] The inside of the front shell 4 is also provided with a connecting plate 43 and a rubber ring 44, which work together to improve the overall sealing and shock resistance of the device. The outside of the front shell 4 is bonded with a silica gel anti-skid layer 41, which improves the feel and stability when holding. In addition, the bowl structure 5 is provided with a decorative ring 3 and a recess part 6, which not only beautifies the appearance, but also increases the comfort of use.
[0043] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
