For the convenience of the user, the through hole 15 on the base 42 for the rotating shaft 41 to pass does not completely coincide with the movable track 12 to facilitate initialization. In this state, the rotating shaft 41 is stuck in the through hole 15, thereby adjusting the front and rear inclination angle of the flat plate 1 and at the same time adjusting the oblique position of the flat plate 1. When the user needs to adjust the oblique position, the flat plate 1 is lifted upward to move the rotating axis. Entering the movable track 12, the rotation axis 41 can slide relatively in the movable track 12 to cooperate with the forward and backward swing and lifting of the arc-shaped support arm to achieve a better viewing angle and position posture for the user.

Preferably, the rotating shaft 41 has a second threaded section 16 that passes through the arc-shaped support arm and the base 42. The second threaded section 16 is provided with a second tightness adjusting member for adjusting the tightness between the arc-shaped support arm and the base 42. 17. Specifically, the second elastic adjustment member 17 is also a hand-tightened nut. Through the second elastic adjustment member 17, the rotating shaft 41 can be locked at any position in the movable track 12, making it convenient for the user to adjust the tablet 1 according to his or her own wishes. In addition, the damping sliding method of the rotating shaft 6 and the inner wall of the through hole 7 can also be used to achieve the stop at any position.

Preferably, in the initial state, the flat plate 1 is tilted and the lower end of the upper surface is provided with a bracket 18 for supporting items. The bracket 18 is provided with an elastic anti-detachment strip that presses the items tightly against the flat plate 1. 19. The bracket 18 is also provided with a storage position for storing the anti-falling strip 19. Furthermore, the bracket structure is made of transparent material to enhance the aesthetics of the product.
