[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 A user-friendly pencil case includes a carrying box 1 and a lid 2. The carrying box 1 has a carrying cavity, and the lid 2 closes the carrying cavity. The carrying cavity of the carrying box 1 is used to store various stationery items such as pencils, pens, erasers, and rulers. The lid 2 is hinged to the back of the carrying box 1 and can rotate around the hinge to open and close the carrying cavity. When stationery needs to be used or stored, opening the lid 2 allows the stationery to be easily placed into or taken out of the carrying cavity, while closing the lid 2 protects the stationery.

[0028] The handwriting tablet 3 embedded at one end of the lid 2 and the calculator 4 embedded at the other end provide students with additional learning functions. The handwriting tablet 3 can be used to write, draw, and perform other operations on its surface using the accompanying stylus or finger, meeting students' needs for recording information; the calculator 4 has calculation functions, which students can use directly when performing mathematical or physical calculations without having to carry an additional calculator, making it convenient and quick.

[0029] In the cover plate 5 assembly, the limiting block 8 on the cover plate 5 is aligned with the notches on the left and right sides below the box cover 2 and inserted. When the limiting block 8 is fully inserted into the notch, the cover plate 5 is connected to the box cover 2 through the connector. At this time, the filling block 6 above the cover plate 5 presses against the battery compartment of the handwriting tablet 3 and the calculator 4, which plays the role of fixing the battery and preventing the battery from shaking during use.

[0030] In this embodiment, the connector includes a limiting block 8, an insert block 9, an elastic element, and an unlocking block 10. The limiting block 8 is adapted to the notch, and movable grooves are symmetrically arranged on the front and rear sides of the limiting block 8. The two ends of the elastic element are respectively connected to the inner wall of the movable groove and the insert block 9. The cover 2 is also provided with an insertion hole adapted to the insert block 9. An unlocking groove is provided below the limiting block 8, and a sliding hole is provided on the limiting block 8 to pass through the unlocking groove. An unlocking block 10 is provided below the insert block 9, extending into the unlocking groove through the sliding hole. In the cover plate 5 assembly, the limiting block 8 on the cover plate 5 is aligned with the notches on the left and right sides below the cover 2 and inserted. Since the insert block 9 has an inclined surface above the end away from the elastic element, during the insertion process, the cover 2 applies pressure to the inclined surface of the insert block 9, causing the insert block 9 to compress the elastic element (spring 11 and telescopic rod 12) and move into the movable groove. When the limiting block 8 is fully inserted into the notch and the insert block 9 is aligned with the insertion hole on the cover 2, the elastic element returns to its original state, pushing the insert block 9 into the insertion hole, thereby fixing the cover plate 5 to the cover 2. At this time, the filling block 6 above the cover plate 5 abuts against the battery compartment of the handwriting pad 3 and the calculator 4, which serves to fix the battery and prevent the battery from shaking during use;

[0031] When the battery needs to be replaced, open the cover 2 and simultaneously press the corresponding unlocking block 10 with both hands. The unlocking block 10 pushes the insert 9 into the movable slot through the sliding hole, compressing the elastic element. Once the insert 9 is completely disengaged from the socket, the cover 5 can be removed from the cover 2, allowing easy access to the battery compartments of the handwriting tablet 3 and calculator 4 for battery replacement. After replacing the battery, reinstall the cover 5 following the installation steps.

[0032] Several sets of C-shaped elastic holders 7 are located below the cover plate 5 to hold the pen. When the pen is placed in the elastic holder 7, the C-shaped elastic holder 7 will undergo a certain elastic deformation due to the insertion of the pen, thereby clamping the pen tightly and placing it securely inside the elastic holder 7. When carrying the pencil case, the pen will not roll or collide inside the case, protecting the pen while also making it convenient for students to take it out and use it at any time.
