[0013] When in use, the exhibits are placed in the display slots at the bottom of the mounting assembly. The partitions in the display slots can display multiple exhibits in categories. With the use of the electronic display screen above each display slot, the information of the corresponding exhibits can be displayed on the electronic display screen through data visualization, and operations can also be performed on the electronic display screen, so as to achieve the purpose of interactive display;

[0014] When the device is not in use, the handle is lifted up, and the handle drives the clamping rod to move up and out of the clamping slot on the connecting plate. Then, the handle is held to push the connecting rod, so that the end of the connecting rod rotates inside the bearing seat, so that the clamping rod and the clamping slot are not on the same vertical line. After releasing the handle, the brake pad in the universal wheel is opened, so that the universal wheel is in a free movable state, and the column is pushed to drive the universal wheel to roll on the ground through the bottom plate. The connecting shaft inside the column can push the first ear plate through the first shaft sleeve, and the first ear plate drives multiple connecting plates on one side to rotate, because the middle part of the connecting plate and the baffle plate is connected by a pin rod;

Then, the handle is held to push the connecting rod, so that the end of the connecting rod rotates inside the bearing seat, so that the clamping rod and the clamping slot are not on the same vertical line. The column is pushed to drive the universal wheel to roll on the ground through the bottom plate. The connecting shaft inside the column can push the first ear plate through the first shaft sleeve, and the first ear plate pushes multiple connecting plates on one side to rotate. The baffle is hinged with the second ear plate through the pin shaft, so that the connecting plate and the baffle can rotate around the pin rod, and the electronic display screen on the baffle and the connecting plate The two electronic display screens can be deflected synchronously so that the two electronic display screens can rotate relative to each other without the screens being exposed. As the baffle and the connecting plate gradually approach each other, the screen in the electronic display screen can be protected.

After releasing the handle (507), the brake pad in the universal wheel (1003) is opened, so that the universal wheel (1003) is The wheel (1003) is in a free-moving state, pushing the column (1001) to drive the universal wheel (1003) to roll on the ground through the bottom plate (1002), and the connecting shaft (1004) inside the column (1001) can push the first ear plate (1006) through the first shaft sleeve (1005), and the first ear plate (1006) pushes the multiple connecting plates (301) on one side to rotate, because the middle part of the connecting plate (301) and the baffle plate (302) are connected by the pin rod (303); The baffle (302) is hinged to the second ear plate (2004) through a pin shaft, so that the connecting plate (301) and the baffle (302) can rotate around the pin rod (303), and the electronic display screen (7) on the baffle (302) and the connecting plate (301) can be deflected synchronously, so that the two electronic display screens (7) can rotate relative to each other without the screens being exposed. As the baffle (302) and the connecting plate (301) gradually approach each other, the screen in the electronic display screen (7) can be protected. At this time, the storage work of the baffle (302), the connecting plate (301) and the electronic display screen (7) on one side is completed. Similarly, the locking assembly (5) on the other side is operated to make the two columns (1001) approach each other and complete the storage of the device. Secondly, the handle (507) is lifted to drive the card rod (504) to move upward, so that the retaining ring (505) outside the card rod (504) can squeeze the spring (506). When the handle (507) is pushed to move the card rod (504) to the top of the card slot (4), the handle (507) is released, and the retaining ring (505) is supported by the elastic force of the spring (506), so that the retaining ring (505) drives the card rod (504) to move downward and snap into the card slot (4), thereby achieving the purpose of locking the connection plate (301) and the retaining plate (302). Secondly, the column (1001) or the fixed column (2001) is pushed to make the universal wheel (1003) and the walking wheel (2005) roll on the ground, so that the display device can be transferred; When unfolding the display device, the handle (507) is lifted to drive the card rod (504) to move upward and out of the card slot (4), and the handle (507) is held to push the connecting rod (501) to form a misalignment between the card rod (504) and the card slot (4), and the column (1001) is pulled to drive the first shaft sleeve (1005) and the first ear plate (1006) to move through the connecting shaft (1004), and the first ear plate (1006) pulls the baffle plate (302) or the connecting plate (301) to move. Since the baffle plate (302) is hinged to the connecting plate (301) through the pin rod (303), the connecting plate (301) and the baffle plate (302) can drive the electronic The display screen (7) is rotated so that the screen of the electronic display screen (7) can be exposed to the outside, and interactive display can be performed in cooperation with the exhibits in the display slot (6). The orientation of the electronic display screen (7) is adjusted by adjusting the position of the column (1001), so as to achieve the purpose of multi-directional interactive display. The handle (507) is lifted to drive the clamping rod (504) to move upward. When the clamping rod (504) is moved to the top of the clamping slot (4), the handle (507) is released, and the clamping rod (504) is clamped into the clamping slot (4) by the elastic force of the spring (506), so that the position of the connecting plate (301) and the baffle plate (302) can be locked, thereby improving the use stability of the display device.
