Referring to FIG. At this time, the sliding arc surface 333 of the inner base wall 332 will be driven by the second connecting wall 331, and take the arc center C common to the guiding arc surface 315 and the sliding arc surface 333 as the axis center relative to The guiding arc surface 315 slides in the rotation direction R. At the same time, the guiding through hole 335 will be changed from the position of the first protruding portion 316 and the second protruding portion 322 at the position of the guiding through hole 335 adjacent to the second connecting wall 331 to the position of the first protruding portion 316 and the second connecting wall 331 . The two protrusions 322 are located at a position where the guiding through hole 335 is away from the second connecting wall 331 . Moreover, the assembling surface 334 also slides relative to the arc surface of each engaging member 34 to drive the shielding plate 35 to move. In this way, the second display surface 22 can also be rotated toward the rotation direction R with the common arc center C of the guide arc surface 315 and the sliding arc surface 333 as an axis, thereby reducing the size of the second display surface 22 and the The included angle θ between the first display surfaces 12 .
