The angle adjustment member 30 is arc-shaped, and the first end of the angle adjustment member 30 is slidably disposed in the first base 10, and the second end of the angle adjustment member 30 is slidably disposed in the second base 20. The angle adjustment member 30 can adjust the distance between the first base 10 and the second base 20. The first fastener 40 is connected to the first end of the angle adjustment member 30 and the first base 10. The second fastener 50 is connected to the second end of the angle adjustment member 30 and the second base 20. The elastic reset member 60 is connected between the first base 10 and the angle adjustment member 30. When the first fastener 40 loosens the first end of the angle adjustment member 30 and the first seat body 10, and when the second fastener 50 loosens the second end of the angle adjustment member 30 and the second seat body 20, the elastic reset member 60 applies an elastic reset force to the angle adjustment member 30 so that the angle adjustment member 30 can retract into the first seat body 10.

[0034] In this way, the first base 10 is set on one of the two adjacent boxes 70, and the second base 20 is set on the other of the two adjacent boxes 70. By adjusting the distance that the first end of the angle adjustment member 30 slides into the first base 10 and the distance that the second end of the angle adjustment member 30 slides into the second base 20, the relative position between the first base 10 and the second base 20 can be adjusted to adjust the position between the two adjacent boxes 70, so that the shape of the front surface of the LED display device can be adjusted to form a flat screen, an inner arc screen or an outer arc screen.

The first fastener 40 is connected to the first end of the angle adjustment member 30 and the first base 10. The second fastener 50 is connected to the second end of the angle adjustment member 30 and the second base 20. The elastic reset member 60 is connected between the first base 10 and the angle adjustment member 30. Among them, when the first fastener 40 loosens the first end of the angle adjustment member 30 and the first seat 10, and when the second fastener 50 loosens the second end of the angle adjustment member 30 and the second seat 20, the elastic reset member 60 applies an elastic reset force to the angle adjustment member 30 so that the angle adjustment member 30 can be retracted into the first seat 10. In this way, the setting of the first fastener 40 facilitates the sliding and fixing of the first end of the angle adjustment member 30 in the first seat 10, and the setting of the second fastener 50 facilitates the sliding and fixing of the second end of the angle adjustment member 30 in the second seat 20. In addition, the setting of the elastic reset member 60 enables the elastic reset member 60 to retract the angle adjustment member 30 into the first seat 10 under the action of the elastic reset force when the two adjacent boxes 70 do not need to be spliced, thereby reducing the collision of the box 70 with the angle adjustment member 30 during transportation. Therefore, the technical solution of this embodiment can solve the problem of troublesome operation when adjusting the position between two adjacent boxes in the related art.
