One side of fixed head generates the cylinder axis of a projection, one side described portable plate correspondingly generate one first groove, described cylinder axis is arranged in first groove, rotates for portable plate relative fixed plate.
One side of fixed head generates one first groove, one side the cylinder axis that correspondingly generates a projection of described portable plate, described cylinder axis is arranged in first groove, rotates for portable plate relative fixed plate.
One second groove is set near the place of being rotationally connected on the fixed head, arranges wherein for an end of described shell fragment, second groove be provided with chamfering be unlikely to skid off this groove so that described shell fragment rotates in this second groove.
One side relative with the place of being rotationally connected is provided with one the 3rd groove on the described portable plate, and the 3rd groove also is provided with a chamfering, is against wherein for the other end of described shell fragment, and when shell fragment rotates, is unlikely to skid off this chamfering.
The length of described shell fragment is fixed head when being connected with first groove by described cylinder axis with portable plate, the distance between second groove and the 3rd groove.
Described portable plate is smooth arc-shaped structure.
Clamp device is four, is arranged on the four edges of lamp box.
After adopting above technical scheme,, only need open that to step up device be detachable transparent panel, with the maintenance of carrying out lamp box inside or change the advertisement picture in maintenance or when changing the advertisement picture.
