[0002] To help schools and teachers understand student attendance and ensure students arrive at school on time, attendance is often managed through a sign-in system. A time clock is a commonly used device for this purpose. The time clock uses a power adapter to convert the main power supply into a specific voltage and current to power the time clock.
[0003] To ensure the proper functioning of the attendance machine, the power adapter's cord has a redundant length. When the two ends of the power adapter are connected to the attendance machine and the socket respectively, the cord is prone to drooping due to the redundant length, which can cause students to trip over the cord or have it pulled apart during the attendance process.
[0004] To address the problems raised in the background art, those skilled in the art have proposed a student attendance management device. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a student management check-in device to solve the problem in the prior art where the power adapter's cable is prone to sagging due to redundant length, causing students to easily get tangled in the cable during the check-in process, tripping or having the cable separated due to traction.
[0006] A student attendance management device includes a card reader connected to a power adapter and a support. A winding rod is movably connected to the support. The power adapter's wiring is wound around the periphery of the winding rod. A turntable is fixedly connected to one end of the winding rod, and an operating lever is fixedly connected to the turntable.

Detailed Implementation
[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0024] Example 1
[0025] As attached Figure 1 To be continued Figure 3 As shown, this utility model provides a student attendance management device, including a card reader 1, through which students complete attendance. The card reader 1 is connected to a power adapter 2, which converts the main power supply into a specific voltage and current to power the card reader 1. The card reader 1 is connected to a bracket 3, of which there are two brackets, located at both ends of a winding rod 4. The winding rod 4 is movably connected to the bracket 3, and can rotate or be pulled and moved on the bracket 3. The power adapter 2's wiring is wound around the winding rod 4 to prevent the wiring from sagging. One end of the winding rod 4 is fixedly connected to a turntable 5, and the turntable 5 is fixedly connected to an operating lever 6. By rotating the operating lever 6, the turntable 5 is rotated, which in turn rotates the winding rod 4.
[0026] As can be seen from the above, by rotating the operating lever 6, the turntable 5 is rotated, which in turn drives the winding rod 4 to rotate, winding the power adapter 2's wires onto the winding rod 4. Then, the two ends of the power adapter 2 are connected to the time clock 1 and the socket respectively. Finally, the bracket 3 is installed at the lower end of the time clock 1. Since the power adapter 2's wires are wound onto the winding rod 4, there is no risk of the wires falling, thus avoiding accidents.
[0027] Example 2
[0028] As attached Figure 2 As shown, this embodiment is basically the same as the previous embodiment, except that the bracket 3 is fixedly connected to a collar 7, the collar 7 is provided with a toothed groove 8, and the turntable 5 is provided with a fixed tooth 9. The shapes of the toothed groove 8 and the fixed tooth 9 are matched. When the fixed tooth 9 is located in the toothed groove 8, the winding rod 4 cannot rotate.
[0029] As attached Figure 2 To be continued Figure 3 As shown, specifically, the other end of the winding rod 4 is fixedly connected to an anti-detachment plate 10. The anti-detachment plate 10 and the turntable 5 cooperate to prevent the winding rod 4 from detaching from the bracket 3. A first spring 11 is sleeved on the periphery of the winding rod 4. When the winding rod 4 slides on the bracket 3, the first spring 11 deforms and stores energy to prepare for the winding rod 4 to reset. The first spring 11 is fixedly connected to the bracket 3.
[0030] As attached Figure 3 To be continued Figure 4As shown, the bracket 3 further includes a receiving groove 12, to which a rod 13 is slidably connected. The rod 13 can slide within the receiving groove 12. A plate 14 is fixedly connected to the rod 13. A second spring 15 is sleeved around the periphery of the rod 13. The winding rod 4 includes a positioning groove 16. When the winding rod 4 moves toward the turntable 5, the positioning groove 16 moves to align with the receiving groove 12. At this time, the second spring 15 causes the rod 13 to enter the positioning groove 16, preventing the winding rod 4 from moving and allowing it to rotate.
[0031] As attached Figure 3 To be continued Figure 4 As shown, one end of the second spring 15 is fixedly connected to the insert plate 14, and the other end of the second spring 15 is fixedly connected to the bracket 3. The positioning groove 16 is an annular groove. When the winding rod 4 rotates, the positioning groove 16 can still restrict the movement of the winding rod 4.
[0032] As can be seen from the above, by pulling the operating lever 6, the take-up lever 4 is moved towards the turntable 5. At this time, the first spring 11 is compressed until the receiving groove 12 is aligned with the positioning groove 16. Then, the second spring 15 causes the insertion rod 13 to enter the positioning groove 16, thus preventing the take-up lever 4 from moving and allowing it to rotate. By rotating the operating lever 6, the take-up lever 4 is rotated, and the power adapter 2's wiring is wound around the take-up lever 4. Then, the insertion rod 13 is pulled out from the positioning groove 16, and the first spring 11 causes the take-up lever 4 to reset and the turntable 5 to rotate at a certain angle, thus causing the fixing tooth 9 to engage in the tooth groove 8. At this time, the take-up lever 4 cannot rotate, preventing the power adapter 2's wiring from becoming loose due to accidental rotation of the take-up lever 4.
[0033] Example 3
[0034] As attached Figure 2 and attached Figure 5 As shown, this embodiment is basically the same as the previous embodiment, except that a limiting groove 17 is provided at the lower end of the time clock 1. The diameter of the opening of the limiting groove 17 is smaller than the diameter of the cavity inside the limiting groove 17. A through groove 18 is provided on the bracket 3. A post 19 is connected to the limiting groove 17 and the through groove 18. After the post 19 is inserted into the through groove 18 and the limiting groove 17, the bracket 3 and the time clock 1 will be connected together. A fitting groove 20 is provided on the periphery of the post 19 for fitting. The lower and upper ends of the groove 20 are respectively fitted to the edges of the through groove 18 and the limiting groove 17, thereby preventing the insertion post 19 from shaking. The upper end of the insertion post 19 is provided with a polymerization groove 21. The insertion post 19 is made of elastic material. The upper end of the insertion post 19 is larger than the opening of the limiting groove 17 and the through groove 18. When the insertion post 19 is inserted into the through groove 18 and the limiting groove 17, the upper end of the insertion post 19 can be deformed due to the polymerization groove 21, thereby allowing the upper end of the insertion post 19 to be inserted into the limiting groove 17.
[0035] As can be seen from the above, the bracket 3 and the card reader 1 are aligned through the through groove 18 and the limiting groove 17. Then, the insert post 19 is passed through the through groove 18 and inserted into the limiting groove 17. Although the upper end of the insert post 19 is larger than the opening of the limiting groove 17 and the through groove 18, the upper end of the insert post 19 is provided with a gathering groove 21. When the insert post 19 is inserted into the through groove 18 and the limiting groove 17, the upper end of the insert post 19 is deformed and gathered by the gathering groove 21, so that the upper end of the insert post 19 is inserted into the limiting groove 17. After the upper end of the insert post 19 is completely inserted into the depth of the limiting groove 17, it returns to its original shape. At this time, the fitting groove 20 fits with the edge of the through groove 18 and the limiting groove 17, thereby preventing the insert post 19 from shaking and connecting the card reader 1 and the bracket 3 together. When disassembling, the insert post 19 can be pulled out by force downwards. The deformed insert post 19 is pulled out.
