Typically, two of the limiting holes 5 of the limiting plate 4 are selected to fix the distance between the crossing points formed in the two sets of scissors structures. More preferably, the two groups of scissors structures are two adjacent groups of scissors structures; the specific operation example is that when the folding leg 11 is adjusted to a required height, the bolts 3 near the middle parts of the two sets of scissors structures on the lower beam 6 are firstly removed, the limiting piece 4 is attached to the folding leg 11, then the stretching degree of the scissors-shaped support is adjusted in a small range to enable the two limiting holes 5 on the limiting piece 4 to be opposite to the cross points near the middle parts of the two sets of scissors structures on the lower beam 6, then the bolts 3 are installed again and screwed, and meanwhile, the bolts 3 at the middle parts of the remaining scissors-shaped structures are screwed, so that the scissors-shaped support is completely stable in a stretching state through the supporting function of the limiting piece 4.

Preferably, a wiring hole for a wiring circuit to penetrate into the base 7 and be connected with the flexible electronic screen is formed in the side wall where the non-rectangular opening 10 of the base 7 is located, so that a lead can be conveniently led out, and the lead can be connected with an external display driving module for display driving of the flexible electronic screen.

More preferably, the weight member 13 is a rechargeable lithium battery power source, and can provide power source without external power source if necessary, so as to ensure normal operation of the display driving module and normal display of the flexible electronic screen.

The structure is used for an electronic display board which adopts a flexible electronic screen as a display interface, and the specific scheme is as follows:

it should be noted that the flexible electronic screen in this embodiment generally refers to "electronic paper" -a flexible Eink display screen, and the display of the flexible electronic screen may be color or black and white, and is available as needed. However, this does not exclude that a flexible electronic screen made using the 0LED principle is also suitable for the holder in this embodiment.

Firstly, connecting a lead wire used for being connected with a display control circuit by the flexible electronic screen, then fixing one end of the flexible electronic screen, which is connected with the lead wire, on the roller 8, paying attention to the fact that the joint of the lead wire needs to be reinforced and sealed (such as glue sealing, or fixing more lead wire cables on the roller 8 in advance by using a protective adhesive tape so as to avoid bending of the joint of the lead wire in the processes of rolling and pulling out) and prevent the lead wire from being damaged in the subsequent processes of rolling and pulling out; and one end of the flexible electronic screen, which is not provided with the lead, is fixedly connected with the bottom end surface of the convex beam 9 on the upper cross beam 1. The bolt 3 for fastening the intersection of the two supporting sheets 2 in the scissors structure is loosened, the upper cross beam 1 is pushed downwards to fold and contract the folding frame 11 to the lowest position, and then the roller 8 is manually rotated through the end of the roller 8 extending out of the roller 8 to roll up the flexible electronic screen on the roller 8 as much as possible. At the moment, the whole electronic display board with the flexible electronic screen is in a storage state, small in size and convenient to carry and transport.

When the flexible electronic screen is needed to be used, the upper beam 1 is pulled by hands, so that the folding frame 11 is gradually opened, and in the process that the folding frame 11 is gradually opened, the rotating shaft is rotated in the direction opposite to the rolling direction, so that the flexible electronic screen can extend out of the base 7 along with the opening of the folding frame 11. Because the opening of the folding leg 11 and the rotation of the rotating shaft are carried out synchronously, the flexible electronic screen can not be subjected to overlarge tension in the pulling process, the problem that the flexible electronic screen is damaged by the tension is avoided, and meanwhile, the flexible electronic screen can be kept in a weak tensioning state, so that the display surface formed by the whole flexible electronic screen is smoother. When the upper cross member 1 of the folding leg 11 is pulled up to a desired height, bolts 3 each for fastening the opposite positions of the two support pieces 2 crossing each other in the corresponding scissors structure are tightened to structurally stabilize the folding leg 11. Preferably, in order to further enhance the stability of the extended folding leg 11, the spacing between two corresponding intersections can be fixed by using the limiting piece 4, so as to thoroughly avoid the problem of the change of the opening and closing degree of the folding leg 11 caused by the looseness of the bolt 3. Finally, the connection port 12 arranged on the base 7 in a locking mode is used for connecting a lead on the flexible electronic screen with an external display driving module, and meanwhile, the external display driving module is supplied with power by an external power supply, so that the display of the content of the flexible electronic screen is realized, the displayed content can be changed and replaced by different display commands output by the display driving module, and then the same electronic display board can alternately display various information. When the power supply condition is limited, a lithium battery power supply serving as a balancing weight 13 can be used for supplying power to the display driving module so as to improve the mobility of the whole electronic display board; at the moment, the optimized flexible electronic display screen adopts a flexible electronic ink screen, so that the energy consumption can be effectively controlled, and the longer display endurance time is realized.

Preferably, the display driving module for the flexible electronic screen can be integrated into the rear portion of the cavity of the base 7, at this time, the wiring port 12 for wiring is replaced by a data interface for data input, and the power supply of the flexible electronic screen and the display driving module can adopt an external power supply, and can also more conveniently adopt a lithium battery power supply as the balancing weight 13. The electronic display board obtained by the method has more perfect functions and can be suitable for more outdoor scenes. It should be emphasized that, when the flexible electronic display board is used in outdoor scenes, the whole electronic display board needs to be subjected to waterproof treatment, such as a display driving module and a lithium ion power supply, which need to be sealed and waterproof, and a transparent waterproof layer should be coated and fixed on the surface of the flexible electronic screen.

Preferably, the convex beam 9 and the upper cross beam 1 are in magnetic fixed connection through magnets which are correspondingly fixed in the convex beam 9 and the upper cross beam 1 and have mutual attraction, so that the convex beam 9 and the upper cross beam 1 can be separated in the storage process, the flexible electronic screen can be completely collected into the base 7, and more comprehensive damage prevention protection can be achieved; meanwhile, through the limiting effect between the convex beam 9 and the rectangular opening 10, the convex beam 9 is always positioned outside the rectangular opening 10, and the problem that the flexible electronic screen cannot be pulled out after being completely collected into the base 7 is solved.

The above-mentioned embodiments only express the specific embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for those skilled in the art, without departing from the technical idea of the present application, several changes and modifications can be made, which are all within the protection scope of the present application.
