The disc 12 is set in the cavity 18 of the sub-plate 7 and inserted into the notch 16 of each card plate 15. A plurality of arc-shaped openings 13 are evenly arranged on the disc 12. The design of the arc-shaped openings 13 is inclined to the radial direction of the disc 12. A slide bar 14 is set at the position corresponding to the arc-shaped opening 13 between the notches 16 of each card plate 15. The design of the arc-shaped opening 13 satisfies that the rotation of the disc 12 can make the arc-shaped opening 13 push the slide bar 14 to drive the card plate 15 to extend to the limit. The disc 12 is fixedly mounted on the side wall of the display screen 9 and inserted into the card slot 17 or retracted into the limiting opening 20. A rotating shaft 11 is fixedly arranged at the center of the side wall of the disc 12 away from the display screen 9. The rotating shaft 11 passes through the side wall of the sub-board 7 and the upper end of the supporting assembly and can rotate. A rotating handle 10 is arranged at the through end of the rotating shaft 11. The supporting assembly includes a telescopic seat 2, a telescopic plate 3 and a base 1. The telescopic seat 2 is fixedly arranged on the upper surface of the base 1. A slot matching the telescopic plate 3 is vertically opened on the upper end surface of the telescopic seat 2. The lower end of the telescopic plate 3 is inserted into the slot. The sub-board 7 and the telescopic plate 3 are connected to each other. The upper end side wall of the retractable plate 3 is fixedly connected, and a plurality of screw holes 4 are vertically arranged on the telescopic plate 3. The telescopic seat 2 passes through the screws 5 and is screwed to the screw holes 4 of the telescopic plate 3; a torsion spring 19 is arranged between the rotating handle 10 and the telescopic plate 3 and is sleeved on the rotating shaft 11, and the force of the torsion spring 19 makes the clamping plate 15 tend to extend out of the limit opening 20; the rotating shaft 11 passes through the center position of the disk 12 corresponding to one end of the disk 12, and is rotatably connected to the inner side wall of the cavity 18 of the sub-plate 7, and the disk 12 is fixedly connected to the rotating shaft 11; a self-locking universal wheel is arranged at the bottom of the base 1.

[0026] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0027] In the utility model, the motherboard 6 is fixedly arranged on the rear side wall of the display screen 9 and does not move for a long time, and can be designed during production.

[0028] According to the instruction manual Figure 1-7 It can be seen that in the utility model, a mounting groove 8 is provided on the side wall of the motherboard 6, and the sub-board 7 on the supporting assembly can be inserted into the mounting groove 8. The sub-board 7 is a box with a cavity 18 therein, and the optimal rectangular box is inserted into the mounting groove 8 to ensure that the motherboard 6 and the display screen 9 cannot rotate, and at the same time ensure that the limit opening 20 on the end face of the sub-board 7 can correspond to the slot of the motherboard 6; rotating the handle 10 can drive the rotating shaft 11 and the disk 12 in the cavity 18 of the sub-board 7 connected to the rotating shaft 11 to rotate, and the disk 12 is provided with an arc opening 13, the arc center of the arc opening 13 deviates from the center of the disk 12, and one end of the arc opening 13 is close to the disk 12 center, the other end is close to the edge, inclined in the radial direction of the disc 12, the rotation of the disc 12 can make the arc-shaped opening 13 push the slide bar 14 to drive the card plate 15 to extend out of the limit opening 20 and insert into the card slot 17, fix the sub-board 7 and the motherboard 6, and achieve the purpose of connecting the display screen 9 connected to the motherboard 6 and the supporting assembly connected to the sub-board 7. The support frame is composed of only the supporting assembly, the sub-board 7, the motherboard 6 and the structure inside the sub-board 7. The overall structure is small, convenient for transportation, and suitable for a wide range of environments. It is also easy and quick to install. When disassembling, only the handle 10 needs to be rotated in the opposite direction to remove the display screen 9 and the motherboard 6, and the disassembly is also relatively convenient.

[0029] The supporting assembly includes a telescopic seat 2, a telescopic plate 3 and a base 1. The telescopic seat 2 is fixedly arranged on the upper surface of the base 1. The base 1 is used to balance the entire device. A self-locking universal wheel can be arranged at the bottom of the base 1 for easy movement. A slot matching the telescopic plate 3 is vertically opened on the upper end surface of the telescopic seat 2. The lower end of the telescopic plate 3 is inserted into the slot and can be telescoped in the vertical direction, so that the height of the terminal board 7, the motherboard 6 and the display screen 9 on the telescopic end can be adjusted. The telescopic seat 2 and the telescopic plate 3 are screwed to the screw holes 4 at different heights on the telescopic plate 3 by screws 5 to achieve the purpose of fixing. The fixing method is simple and convenient. The sub-plate 7 is fixedly connected to the upper side wall of the telescopic plate 3. The rotating shaft 11 runs through the side wall of the sub-plate 7 and the side wall of the telescopic plate 3 and can rotate relatively.

[0030] Among them, a torsion spring 19 is arranged between the handle 10 and the telescopic plate 3 and is sleeved on the shaft 11. The force of the torsion spring 19 makes the shaft 11, the handle 10 and the disc 12 tend to push the slide bar 14 in the arc-shaped opening 13 to the side away from the center of the circle. Even if the card plate 15 tends to be extended, the handle 10 is rotated during installation to retract the card plate 15, the sub-board 7 is inserted into the installation slot 8 of the motherboard 6, and the handle is released. The card plate 15 automatically extends into the card slot 17 of the motherboard 6 and will not be retracted without external force. The installation is stable and safe.

[0031] In addition, the rotating shaft 11 corresponds to one end of the disc 12 and passes through the center position of the disc 12, and is rotatably connected to the inner wall of the cavity 18 of the sub-plate 7. The disc 12 is fixedly connected to the rotating shaft 11. The rotating shaft 11 can drive the disc 12 to rotate stably, and the telescopic effect of the clamping plate 15 will not be affected by the tilting of the disc 12.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
