[0002] In daily life, including study, work, and daily activities, people often need to use writing tools for recording and creating. Traditional writing tools, such as ordinary writing boards, have many limitations. Their fixed size makes it difficult to meet the diverse writing area requirements of different content. When writing long passages of text or drawing large charts, a fixed-size writing board often proves inadequate; while for simple note-taking, an oversized writing board is inconvenient to carry. Existing writing tools lack flexibility in terms of support structure and angle adjustment. Many writing boards can only be used on a horizontal table and cannot be adjusted to suit the user's needs. Prolonged use can easily lead to neck and back fatigue, especially in certain work scenarios, such as outdoors or inside a vehicle, where a fixed-angle writing tool is extremely inconvenient.

The positioning plate 107 is fixedly connected to the top of the limiting groove 104, and the extension rod 106 is movably connected inside the limiting groove 104.

[0031] Further explanation is needed:

[0032] The first support rod 101, the adapter tube 102, and the second support rod 103 constitute the main frame. Through the adapter tube 102, the first support rod 101 and the second support rod 103 can rotate, and the adapter tube 102 itself can be bent 360°. This allows the writing pad to be adjusted to any suitable angle according to the user's needs, whether writing on a horizontal table or tilting at a certain angle for convenient reading. The combination of the limiting groove 104, the slider 105, the extension rod 106, and the positioning plate 107 provides a height adjustment function. Users can flexibly change the height of the positioning plate 107 according to the actual scenario, such as sitting on tables and chairs of different heights, to ensure writing comfort. The design of the locking block 108, the positioning ring 109, the locking plate 110, the first locking hole 111, and the knob 112 facilitates quick and easy locking of the position of the extension rod 106, ensuring the stability and reliability of the support structure.

[0033] The splicing component 2 is mainly responsible for splicing and fixing the writing soft board. The splicing board body 201 is composed of multiple hollow boards that can be spliced ​​left and right. With the cooperation of the clip 202 and the slot 204, the number of splicing boards can be easily increased or decreased, allowing users to freely adjust the width of the writing soft board according to factors such as the amount of writing content and the size of the paper. The first Velcro 205 and the second Velcro 207 are set to firmly fix the writing soft board body 206 to the splicing board body 201, and at the same time, it can be easily disassembled when the writing soft board needs to be replaced. In addition, the second clip hole 203 on the splicing board body 201 is used to cooperate with the insert board component 3, further improving the structure of the entire writing soft board.

[0034] The insert assembly 3 is installed on one side of the splicing board body 201 and plays a unique role. The insert body 301 is used to place some commonly used stationery, paper and other items for easy access by the user. The support plate 302 and the baffle 303 play an auxiliary support and blocking role. The support plate 302 provides additional support to the insert body 301 to ensure its stability. The baffle 303 prevents items placed on the insert from slipping off. The protrusion 304 at the bottom cooperates with the second locking hole 203 on the splicing board body 201 to realize the fixed installation of the insert assembly 3, so that the insert is tightly integrated with the entire writing soft board to form a complete and fully functional portable writing tool.

[0035] The working principle of the above embodiments is as follows:

[0036] First, by utilizing the 360° bending characteristic of the adapter tube 102 and the rotation function of the first support rod 101 and the second support rod 103 around the adapter tube 102, the support assembly 1 is adjusted to a suitable angle. For example, when placed on a desktop, it can be adjusted to a perpendicular angle to the desktop to obtain stable support. At the same time, according to the actual usage scenario, such as the user's height and the height of the table and chair, the slider 105 is moved in the limiting groove 104 to drive the extension rod 106 to move up and down, thereby adjusting the height of the positioning plate 107 to meet the needs of different users. After adjustment, the position of the extension rod 106 is locked by the cooperation of the knob 112, the locking block 108, the positioning ring 109, the locking plate 110 and the first locking hole 111 to ensure the stability of the support structure.

[0037] Secondly, based on the writing needs, select an appropriate number of splicing board bodies 201. Utilizing the fact that the card strips 202 and card slots 204 on the splicing board bodies 201 are the same size, the splicing boards are spliced ​​left and right to adjust the width of the writing board. For example, when writing a large amount of content, the number of splicing boards can be increased; if only simple note-taking is required, the number of splicing boards can be reduced. After splicing, the splicing work of the writing board is initially completed.

[0038] Next, the writing soft board body 206 is placed on the splicing board body 201. The first Velcro 205 at the bottom of the splicing board body 201 is bonded to the second Velcro 207 on the left and right sides of the writing soft board body 206, thus firmly fixing the writing soft board to the splicing board and ensuring that the writing soft board will not shift during the writing process.

[0039] Next, align the protrusion 304 at the bottom of the insert assembly 3 with the second locking hole 203 on the splicing plate body 201, insert and fix it to complete the installation of the insert assembly 3. Then, place commonly used stationery items such as pens, erasers, rulers and papers on the insert body 301. The support plate 302 provides support, and the baffle 303 prevents items from slipping, making it convenient for users to access them at any time.

[0040] Finally, after completing the above steps, the portable writing board is ready for use. Users can write, record, and perform other operations on the writing board. When finished, the operation can be reversed: first, remove the items on the board and disassemble the board assembly 3; then separate the Velcro and remove the writing board; then disassemble the splicing board; finally, adjust the support assembly 1 to make it easy to store and carry.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
