Rod, the guide rod is arranged on the storage box 2, the sliding plate is arranged on the guide rod and slidably cooperates with the guide rod to drive the sliding block to slide smoothly, the connecting rod is rotatably arranged on each sliding plate, and the other end of the connecting rod is rotatably installed with the bottom of the display board 1, and the guide sliding mechanism is used to store and open the display board 1 and extend the mobile support outside the storage box 2. Two pairs of guide holes are opened on the display board 1, and a guide installation rod cooperating with the guide hole is arranged in the storage box 2. The guide installation rod is used to store the display board 1 and slide smoothly in the storage box 2. The support rod 41 and the shielding storage block 51 are rotatably installed with the display board 1 through the damping rod, which can prevent the support rod 41 from tilting freely when supporting, and the bottom end of the support rod 41 is rotatably provided with a rubber sheet in contact with the ground.

[0029] First, pull the support rod 41 outward and adjust it to a suitable angle, and then the support rod 41 slides smoothly along the external shielding storage block 51 and the internal limiting rod 52, and then the support rod 41 can be slid out of the limiting rod 52, so as to provide stable support for the display board 1.

[0030] See also Figure 3 and Figure 5 As shown, the folding storage mechanism 5 also includes a mounting block 53 and a clamping rod 54; the mounting block 53 is arranged on the outside of the shielding storage block 51; the clamping rod 54 is slidably arranged on the mounting block 53, and the clamping rod 54 and the mounting block 53 are clearance-matched, and a second return spring is arranged on the outside of the clamping rod 54, and the two ends of the second return spring are respectively fixed to the ends of the clamping rod 54 and the mounting block 53.

[0031] By means of the second return spring, when the shielding storage block 51 needs to be rotated and opened, the card rod 54 is pulled outward, thereby causing the card rod 54 to move to the outside of the shielding storage block 51 and the support rod 41. At this time, the support rod 41 that has lost the engagement of the card rod 54 can slide and extend inside the shielding storage block 51, thereby making it easier for the support rod 41 to contact the ground and adjust the height, so that the user can make adjustments according to different usage environments.

[0032] See also Figure 3 and Figure 5 As shown, the folding storage mechanism 5 also includes a first return spring 55 and a limiting block 56; the first return spring 55 is arranged on the outer wall of the limiting rod 52, and the two ends of the first return spring 55 are respectively fixed to the limiting rod 52 and the support rod 41; the limiting block 56 is arranged at one end of the limiting rod 52, and the limiting rod 52 and the support rod 41 are both provided with a circular groove, and the circular groove is used to contact and engage with the clamping rod 54 to block the storage block 51 and the display board 1 from being rotatably installed, and a pulling cover is provided at one end of the clamping rod 54, and the limiting block 56 is circular in shape, and the limiting block 56 is used to limit the sliding distance of the support rod 41, and a circular sliding groove is provided on the support rod 41 to slide with the limiting rod 52, and the circular sliding groove is adapted to the outer part of the support rod 41.

[0033] When the card rod 54 is pulled outward, one end of the card rod 54 can extend to the outside of the shielding storage block 51, the limiting rod 52 and the support, so that the support rod 41 that loses the card fixation can perform external stretching along the limiting rod 52 and the shielding storage block 51, and then the support rod 41 can be smoothly extended and retracted.

[0034] See also Figure 5 and Figure 6 As shown, the adjustment and fixing mechanism 6 includes a first positioning rod 61 and a first sliding block 62 arranged on the display board 1; the first positioning rod 61 is arranged on the display board 1 and has a pair; the first sliding block 62 is arranged on the first positioning rod 61 and slidably cooperates with the first positioning rod 61, the first positioning rod 61 has a pair, and the first positioning rod 61 is provided with a travel groove for sliding through.

[0035] The first sliding block 62 is restricted by the first positioning rod 61 so that the first sliding block 62 can slide smoothly along the first positioning rod 61 in a horizontal straight line, thereby facilitating adjustment of the position of the first sliding block 62 .

[0039] When placing display paper on the display board 1, the position can be adjusted by adjusting the first sliding block 62 and the second sliding block 64 to adapt to display paper of different sizes on the display board 1, and then the telescopic spring 65 and the moving block 66 can fix the display paper placed on the display board 1, thereby improving the fixing effect of the display paper.
