[0022] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the support device 500 includes a main rod 501, a secondary rod 502, and a foot 503. The front end of the main rod 501 is movably connected to the connecting seat 203, the end of the main rod 501 is movably connected to the front end of the secondary rod 502, and the end of the secondary rod 502 is movably connected to the foot 503. The main rod 501 is a long rectangular block, and its length is less than the length of the support device storage slot 102. The front end of the main rod 501 has a main rod connecting hole 5011 for connecting to the connecting shaft 2032 of the connecting seat, and the middle part has a storage hole 5011 for storing... The auxiliary rod 502 has an auxiliary rod storage slot 5013, and a main rod connecting shaft 5012 for connecting to the auxiliary rod 502 is provided at its tail. The main rod connecting hole 5011 is a through hole with a radius matching the radius of the connecting seat connecting shaft 2032. The auxiliary rod storage slot 5013 is a double-sided open rectangular slot, with the openings located on the lower and end surfaces of the main rod 501, and the upper surface of the main rod 501 being closed, limiting the rotation angle of the auxiliary rod 502 to between 0° and 180°. The length of the auxiliary rod storage slot 5013 is greater than that of the auxiliary rod 502. The length and depth are greater than the height of the secondary rod 502. The main rod connecting shaft 5012 is cylindrical, and its two ends are fixedly connected to the two side walls of the secondary rod storage groove 5013. The secondary rod 502 is a long rectangular block. The front end of the secondary rod 502 is provided with a first connecting hole 5021 for connecting with the main rod connecting shaft 5012, and the end of the secondary rod 502 is provided with a rectangular notch for storing a pad 503. The rectangular notch divides the end of the secondary rod 502 into two side plates, on which are provided a...

[0023] Furthermore, to prevent damage to the support device 500 due to frequent wear, the front and rear ends of the main rod 501, the auxiliary rod 502, and the pad 503 are rounded. The rounding can prevent the front end of the main rod 501 from contacting the back of the fixing plate 200 and the front end of the auxiliary rod 502 from contacting the upper surface of the main rod 501. On the other hand, it can make the contact between the pad 503 and the wall of the support device storage slot 102 smoother.

[0024] like Figure 1 , Figure 2 , Figure 14 and Figure 15 As shown, the foldable advertising screen bracket is normally in a closed state. In use, the fixing plate 200 is rotated to its maximum angle, at which point the fixing plate 200 is perpendicular to the base 100. The locking buckle 402 is rotated to engage with the locking fastener 403, opening the support device 500. The auxiliary rod 502 is then unscrewed from the auxiliary rod storage slot 5013, and the pad 503 is simultaneously unscrewed. The rotation angle of the main rod 501 is adjusted so that the bottom surface of the pad 503 contacts the bottom of the support device storage slot 102, and the front end of the pad 503 contacts the inner wall of the support device storage slot 102. When not in use, screw the pad 503 into the notch of the auxiliary rod 502, screw the auxiliary rod 502 into the auxiliary rod storage slot 5013, rotate the main rod 501 so that the main rod 501 is parallel to the fixing plate, rotate the latch 402 so that the latch 402 is away from the latch fixing part 403, and finally rotate the fixing plate 200 so that the fixing plate 200 fits into the base. Because the connecting seat 203 corresponds to the position of the support device storage slot 102, the connecting seat 203 and the support device connected to the connecting seat 203 will be inserted into the support device storage slot 102.

[0025] As described above, firstly, the foldable advertising screen bracket of this utility model can flexibly adjust the state of the advertising screen, so that the advertising screen is in a closed state when not in use, effectively saving space. Secondly, through the double fixation of the locking device and the support device, the foldable advertising screen bracket can better maintain a vertical state when in use, and will not tilt or collapse.

[0026] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
