The first rotating shaft 6021 drives the spur gear 6025 to rotate, which makes the rack 6026 engaged with it move in the vertical direction. The rack 6026 pushes the solar charging panel 603 to rise. When the first rotating shaft 6021 rotates, the first connecting plate 6023 fixed thereto rotates with the shaft, which pushes the cover plate 606 to slide outward along the sliding groove of the shell 601 through the hinge point. The synchronous rotation of the second connecting plate 6027 on the second rotating shaft 6022 makes the opening on the shell 601 gradually exposed.
