[0029] Working principle: When the display publicity board body 101 needs to be unfolded, first, pull the display publicity board body 101 to rotate the rotating plate 202 and the fixed rod 201 until the rotating plate 202 rotates to a suitable position, pull the support plate 204 to rotate the support plate 204 with the rotating plate 202 through the hinge seat, so that the return spring A206 is stretched by force, until the support plate 204 rotates to a suitable position, pull the support member 208 to rotate the support member 208 with the receiving groove 207 through the rotating shaft B, so that the insert block 209 is inserted into the slot 210 at a suitable position, at this time, the position of the support plate 204 is fixed, then rotate the display publicity board body 101 to rotate the rotating block 203 with the rotating plate 202 through the rotating shaft A, so that the inclined surface of the limit block 303 squeezes the inner wall of the limit groove 304, so that the limit block 303 slides in the slide groove 301, so that the return spring B When the end of the limit block 303 contacts the inner wall of the next limit slot 304, the return spring B302 is no longer stressed and begins to stretch, so that the limit block 303 slides in the opposite direction in the slide slot 301 until the limit block 303 is engaged with the next limit slot 304. At this time, the position of the display billboard body 101 is fixed. If the position of the display billboard body 101 is not required at this time, the display billboard body 101 is continuously rotated. At this time, the limit block 303 will continuously disengage from the current limit slot 304 and engage with the next limit slot 304, and the return spring B302 will continuously shrink and reset until the display billboard body 101 is rotated to a suitable position, and the display billboard body 101 can be used to post posters.

[0030] When the display and publicity frame body 1 needs to be folded, the support plate 204 is pulled to rotate the support plate 204 and the rotating plate 202 through the hinge seat, so that the return spring A206 is stretched by force until the plug block 209 is disengaged from the insertion of the slot 210. At this time, the support member 208 is put into the receiving groove 207, and the return spring A206 is no longer stressed and begins to shrink, so that the support plate 204 rotates in the opposite direction to the rotating plate 202 through the hinge seat until the support plate 204 contacts the rotating plate 202. At this time, the rotating plate 202 is moved to rotate the rotating plate 202 and the fixed rod 201 in the opposite direction, so that the rotating block 203 rotates in the opposite direction to the rotating plate 202 through the rotating axis A, so that the limit block 303 tilts. The inclined surface squeezes the inner wall of the limit groove 304, causing the limit block 303 to slide in the slide groove 301, causing the return spring B302 to be forced to shrink until the end of the limit block 303 contacts the rotating plate 202. At this time, the return spring B302 no longer shrinks. When the end of the limit block 303 contacts the inner wall of the next limit groove 304, the return spring B302 is no longer stressed and begins to stretch, causing the limit block 303 to slide in the opposite direction in the slide groove 301, causing the limit block 303 to continuously disengage from the current limit groove 304 and engage with the next limit groove 304, and the return spring B302 will continuously shrink and reset until the display promotion board body 101 rotates to its original position. At this time, the folding of the display promotion frame body 1 is completed.

[0031] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes.
