[0023] A novel combination lock pencil case includes a box body 1 and a lid 2, the lid 2 being hinged to the box body 1. The box body 1 has a combination lock structure 4 that allows modification of the unlocking combination, enabling students to set their own passwords for increased security. The combination lock structure 4 includes a movable fastener 41 that can move when unlocked. The lid 2 has a fixed fastener 22 that cooperates with the movable fastener 41. When unlocked, the movable fastener 41 can lock the fixed fastener 22 to prevent the pencil case from being opened. A whiteboard 3 is hinged between the lid 2 and the box body 1, and the whiteboard 3 is horizontally placed on the box body 1. For details, refer to [reference needed]. Figure 3 The inner side of the box body 1 is provided with a support ridge 11. The whiteboard 3 is placed on the support ridge 11 and kept horizontal. The side of the whiteboard 3 closest to the box cover 2 is the writing surface. When it is necessary to write temporarily or make drafts, a whiteboard marker can be used to write on the whiteboard 3. The horizontally positioned whiteboard 3 provides a good writing experience. The box cover 2 is provided with a calculator 5. Specifically, the box cover 1 is provided with a calculator groove. The calculator 5 is placed in the calculator groove to facilitate students to perform mathematical calculations.

[0024] Further reference Figure 4-6 The combination lock structure 4 further includes a housing 42, an unlocking slider 43, a lever 44, a wheel axle 45, a spring 46, two wheel hubs 47, a wheel hub sleeve 48, and three rotating wheels 49. The rotating wheels 49 are sequentially marked with the numbers 0-9. The movable fastener 43 is fixedly connected to the unlocking slider 41. After unlocking, sliding the unlocking slider 43 can drive the movable fastener 41 to move, causing the fixed fastener 22 to disengage.

[0025] Furthermore, the hub 47 and hub 48 are fitted onto the axle 45. The outer sides of the hub 47 and hub sleeve 48 are provided with positioning protrusions 471. The rotating wheel 49 is fitted onto the hub 47 and hub sleeve 48. The inner side of the rotating wheel 49 is provided with ten positioning grooves 491. The positioning protrusions 471 are placed into the positioning grooves 491. When the rotating wheel 49 rotates, it drives the hub 47 or hub sleeve 48 to rotate.

[0026] Furthermore, the axle 45 is provided with three limiting protrusions 451, and the hub 47 and hub sleeve 48 are provided with limiting grooves 472 that match the limiting protrusions 451. When the limiting grooves 472 are not located on the limiting protrusions 451, the hub 47 and hub sleeve 48 can rotate. By rotating the wheel according to the password, the directions of the three limiting grooves 472 are aligned with the directions of the limiting protrusions 451 on the axle. At this time, it is in the unlocked state, and the three limiting protrusions 451 are... 51 can be placed into three limiting grooves 472. The unlocking slider 41 and the movable fastener 43 can push the rotating shaft 45 to move towards the lever 44, so that the movable fastener 43 is disengaged from the fixed fastener 22, thereby unlocking. The spring 46 is sleeved on the wheel axle 45. The wheel axle 45 is provided with a stop plate 452 at one end near the movable fastener 41. The spring 46 is located between the stop plate 452 and the wheel hub 47. When the unlocking slider 41 is released, the spring 46 can push the movable fastener 43 back into place.

[0027] Furthermore, the movable fastener 43 contacts one end of the axle 45, and the hub sleeve 48 is fitted onto the other end of the axle 45. A cylindrical connecting post 481 is provided on the side of the hub sleeve 48 away from the axle. The lever 44 is provided with a connecting groove 441 that matches the connecting post 481, allowing the hub sleeve 48 to rotate relative to the lever 44. In the unlocked state, the lever 44 can be pushed to move the hub 47 and hub sleeve 48 toward the unlocking slider 43, thereby causing the positioning protrusion 471 to disengage from the positioning groove 491. At this time, it is in the setting state, and rotating the wheel 49 will not cause the hub 47 and hub sleeve 48 to rotate. After rotating the wheel to set the desired password, the lever 44 is released. Under the push of the spring 46, the hub 47 and hub sleeve 48 drive the lever 44 to return to its original position, and the positioning protrusion 471 is repositioned into the positioning groove 491, completing the password setting.

[0028] Furthermore, the outer surface of the rotating wheel 49 is provided with ten rotating wheel grooves 492, and the back of the housing 1 is provided with an elastic element 421. When the rotating wheel is rotated, the elastic element 421 can be locked in the rotating wheel grooves 492. The numbers written on the auxiliary rotating wheel 49 face the user and are easy to unlock.

[0029] Furthermore, an electronic clock 6 is also provided on the cover 2 in front of the calculator 5, and a battery cover 61 is provided on the cover at the bottom of the electronic clock 6. A transparent protective shell 21 is hinged to the cover 2 to cover the calculator 5 and the electronic clock 6. The transparent protective shell 21 can protect the calculator 5 and the electronic clock 6, and the time can be seen without opening the protective shell 21.

[0030] Furthermore, a first magnetic component 12 is provided on the side of the box body 1 facing the whiteboard 3, and a second magnetic component 32 is provided on the bottom of the whiteboard 3 directly above the first magnetic component 12, so that the whiteboard 3 can be attached to the box body 1. When the pencil case is not placed on the table, but picked up to use the whiteboard 3 for writing, the magnetic structure can prevent the internal stationery from falling out.

[0031] Furthermore, a pull ring 31 is provided on the side of the whiteboard 3 near the combination lock structure. The pull ring 31 is hinged to the whiteboard 3, making it easy to open the magnetically attracted whiteboard 3.

[0032] Furthermore, a mirror 7 is fixed to the side of the box lid 2 facing the box body 1, which facilitates grooming.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
