The protective plate 5 can protect the touch screen 6 to prevent the touch screen 6 from being attached to dust or being damaged, thereby preventing the use of the attendance device body 1 from being affected, and can meet market demand and is suitable for promotion. When using the utility model, the protective plate 5 is rotated forward along the axis of the rotating shaft 3 to open the protective plate 5, so that the protective plate 5 rotates 180 degrees. The rotation of the protective plate 5 drives the rotating shaft 3 to rotate through several connecting rods 4, and the torsion spring stores energy. Then, the protective plate 5 is limited by the limiting device to prevent the protective plate 5 from rotating and resetting by itself under the action of the torsion spring. Then, the attendance device body 1 is operated through the touch display screen 6. After use, the limiting device on the protective plate 5 is released. Under the action of the torsion spring, the protective plate 5 rotates 180 degrees along the axis of the rotating shaft 3 to reset.
