[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 5 A mathematical formula derivation and verification auxiliary tool includes: a mounting plate 1, a writing whiteboard 2 fixedly connected inside the mounting plate 1, a calculator 3 movably placed on the inner wall of the mounting plate 1, a pen groove 6 opened on the upper surface of the mounting plate 1, the pen groove 6 being located between the writing whiteboard 2 and the calculator 3, a first protective cover 4 movably disposed on the mounting plate 1, the first protective cover 4 being located on one side of the writing whiteboard 2 and the pen groove 6, and a second protective cover 5 movably disposed on the inner wall of the first protective cover 4, the second protective cover 5 being located on one side of the calculator 3.

[0024] In its implementation, this mathematical formula derivation and verification auxiliary tool is suitable for university mathematics applications. The mounting plate 1 restricts the installation positions of the whiteboard 2 and calculator 3. The whiteboard 2 is used for formula derivation and calculation, replacing traditional scratch paper. It is erasable and reusable, making this application more environmentally friendly and improving computational efficiency. The calculator 3 allows operators to perform numerical calculations at any time, improving computational efficiency during the mathematical formula derivation and verification process. A pen slot 6 is provided on the mounting plate 1 to hold a writing pen for quick access and to prevent loss. Furthermore, a first protective cover 4 is movably mounted on the mounting plate 1, and a second protective cover 5 is movably mounted inside the first protective cover 4. The first protective cover 4 can be opened and closed as needed; when closed, it protects the whiteboard from damage. The plate 2 and pen slot 6 are covered for protection. The second protective cover 5 can open and close in sync with the opening and closing of the first protective cover 4. It is specifically designed to protect the calculator 3. The second protective cover 5 and the first protective cover 4 are movably connected, so that when the first protective cover 4 is closed, the second protective cover 5 can be slid open and closed along the connection with the first protective cover 4. This allows the calculator 3 to be opened and used independently, thereby increasing the usability of this application. This mathematical formula derivation and verification auxiliary tool integrates commonly used tools on the same mounting plate 1, which facilitates unified storage and carrying, minimizes the possibility of losing some tools, and also improves the convenience of using this application. It should be noted that the calculator 3 is movably mounted to the mounting plate 1, allowing the operator to disassemble and use the calculator 3 independently, thereby further increasing the usability of this application and making it more practical for actual use.

[0025] refer to Figure 1 and Figure 2 As shown, the mounting plate 1 includes a rectangular plate 101, a pen slot 6 is formed on the upper surface of the rectangular plate 101, a first storage slot 102 and a second storage slot 103 are formed on the upper surface of the rectangular plate 101, the pen slot 6 is located between the first storage slot 102 and the second storage slot 103, the whiteboard 2 is located inside the first storage slot 102, the calculator 3 is located inside the second storage slot 103, and two ear plates 104 are fixedly connected to one side of the upper surface of the rectangular plate 101.

[0026] In the specific implementation process, the first storage slot 102 can restrict the installation position of the whiteboard 2 on the rectangular plate 101, the second storage slot 103 can restrict the installation position of the calculator 3 on the rectangular plate 101, and the ear plate 104 can be hinged to the first protective cover 4, thereby restricting the installation position of the first protective cover 4 on the rectangular plate 101.

[0027] refer to Figure 1 and Figure 2 As shown, both sides of the rectangular plate 101 are provided with disassembly ports 9 that communicate with the second storage slot 103. Both sides of the calculator 3 are fixedly connected with second anti-slip pads 10, and each second anti-slip pad 10 is located inside each disassembly port 9.

[0028] In the specific implementation process, the disassembly port 9 makes it easy for operators to take the calculator 3 out and disassemble it from both sides. When the operator takes the calculator 3 out, the second anti-slip pad 10 increases the friction between the operator's hands and the calculator.

[0029] refer to Figure 1 , Figure 3 and Figure 4 As shown, the first protective cover 4 includes a first rectangular cover plate 401. An installation strip 402 is fixedly connected to one side of the first rectangular cover plate 401. The two ends of the installation strip 402 are hinged to each ear plate 104. A third storage groove 403 is provided inside the first rectangular cover plate 401. The second protective cover 5 is located inside the third storage groove 403. A sliding groove 404 communicating with the third storage groove 403 is provided on the upper surface of the first rectangular cover plate 401. The top of the second protective cover 5 passes through the interior of the sliding groove 404.

[0030] In the specific implementation process, closing the first rectangular cover plate 401 can cover and protect the writing whiteboard 2 and pen slot 6. The hinged connection between the mounting strip 402 and the ear plate 104 can restrict the installation position of the first rectangular cover plate 401. The opening that cooperates with the third storage slot 403 and the sliding groove 404 can restrict the installation and movement position of the second protective cover 5.

[0031] refer to Figure 3 , Figure 4 and Figure 5 As shown, the second protective cover 5 includes a second rectangular cover plate 501 located inside the third storage groove 403. A slider 502 is fixedly connected to the upper surface of the second rectangular cover plate 501. The slider 502 passes through the interior of the slide groove 404. A first anti-slip pad 503 is fixedly connected to the upper surface of the second rectangular cover plate 501.

[0032] In the specific implementation process, by closing the second rectangular cover plate 501 and moving it above the calculator 3, the calculator 3 can be covered and protected. The slider 502 cooperates with the slide groove 404, which makes it easy for the operator to adjust the second rectangular cover plate 501 to slide inside the third storage groove 403. The first anti-slip pad 503 can increase the friction between the second rectangular cover plate 501 and the groove wall of the third storage groove 403. Thus, after the position of the second rectangular cover plate 501 is adjusted, it can play a certain limiting role in preventing the second rectangular cover plate 501 from opening and closing at will.

[0033] refer to Figure 4 and Figure 5 As shown, the second rectangular cover plate 501 has guide holes 7 evenly distributed on one side near the rectangular plate 101, and the third storage groove 403 has guide rods 8 evenly distributed inside. One end of the guide rod 8 is located inside the guide hole 7, and the two are slidably connected.

[0034] In the specific implementation process, the guide hole 7 and the guide rod 8 are used to guide the movement of the second rectangular cover plate 501, thereby enhancing the stability of the second rectangular cover plate 501 when it moves.

[0035] The working principle of the mathematical formula derivation and verification auxiliary tool provided by this utility model is as follows:

[0036] In use, the whiteboard 2 and calculator 3 are mounted on the mounting plate 1, and a pen slot 6 is provided on the mounting plate 1. The operator derives and calculates formulas on the whiteboard 2 and performs numerical calculations on the calculator 3. The writing pen is stored inside the pen slot 6 for easy access, improving the calculation efficiency in the process of mathematical formula derivation and verification. The first protective cover 4 is movably mounted on the mounting plate 1, and the second protective cover 5 is movably mounted inside the first protective cover 4. By closing the first protective cover 4, the whiteboard 2 and pen slot 6 are covered and protected. When the first protective cover 4 closes, the second protective cover 5 also closes, protecting the calculator 3. The second protective cover 5 and the first protective cover 4 are movably connected, allowing the second protective cover 5 to slide open and close independently along the connection point with the first protective cover 4 when the first protective cover 4 is closed, so that the calculator 3 can be opened and used independently. This mathematical formula derivation and verification auxiliary tool integrates commonly used tools on the same mounting plate 1, which facilitates unified storage and carrying, minimizes the possibility of losing some tools, and also improves the convenience of using this application.
