A first slide bar 12 passes through at least two first movable seats 14; two second slide bars 15 are installed on both sides of the movable frame 13; a first display screen assembly 16 is located on the side of the stand 11 away from the movable frame 13; at least two second movable seats 17 are installed on the side wall of the first display screen assembly 16 near the stand 11, and the two second slide bars 15 pass through at least two second movable seats 17; the end of the second display screen assembly 18 is rotatably connected to the top of the first display screen assembly 16; and a third display screen assembly 19 is connected to the bottom of the first display screen assembly 16.

[0039] By mounting the upright frame 11 on the base 10 and mounting two first sliding rods 12 on both sides of the upright frame 11, the base 10 supports the upright frame 11, thereby supporting the two first sliding rods 12 and improving the stability of the two first sliding rods 12. By positioning the movable frame 13 on one side of the upright frame 11 and mounting multiple first movable seats 14 on the side wall of the movable frame 13 near the upright frame 11, and allowing the two first sliding rods 12 to pass through the multiple first movable seats 14 respectively, the movable frame 13 can move up and down along the two first slide rails via the multiple first movable seats 14, thereby adjusting the relative position of the movable frame 13 and the upright frame 11. By installing two second slide rods 15 on both sides of the movable frame 13 and installing multiple second movable seats 17 on the side wall of the first display assembly 16, and by having the two second slide rods 15 pass through the multiple second movable seats 17 respectively, the first display assembly 16 can move up and down along the two second slide rods 15 via the multiple second movable seats 17, thereby adjusting the relative position between the first display assembly 16 and the movable frame 13; by rotatably connecting the end of the second display assembly 18 to the top of the first display assembly 16, the first display assembly 16 and the second display assembly 18 can rotate relative to each other, thereby enabling the first display assembly 16 and the second display assembly 18 to unfold to form a whole screen, and at the same time, the first display assembly 16 and the second display assembly 18 can also be folded together, thereby reducing the space occupied by the product.

[0040] In actual use of the product, firstly, the movable frame 13 is moved upward along the two first slide bars 12 via multiple first movable seats 14, thereby moving the movable frame 13 to its highest position; then, the first display screen assembly 16 is pushed upward, causing the first display screen assembly 16 to move upward along the two second slide bars 15 via multiple second movable seats 17, thereby moving the first display screen assembly 16 to its highest position; next, the second display screen assembly 18 is rotated so that the second display screen assembly 18 and the first display screen assembly 16 are on the same plane; then, the third display screen assembly 19 is connected to the bottom of the first display screen assembly 16, thereby enabling the first display screen assembly 16, the second display screen assembly 18, and the third display screen assembly 19 to... The screen is assembled into a single unit. When preparing to transport the product, the third display assembly 19 is first removed from the first display assembly 16 and stored. Then, the first display assembly 16 is pushed downward, causing it to move downward along two second slide bars 15 via multiple second movable seats 17. At the same time, the second display assembly 18 is rotated, causing the first display assembly 16 and the second display assembly 18 to fold together. Then, the movable frame 13 is pushed downward, causing it to move downward along two first slide bars 12 via multiple first movable seats 14, thereby placing the movable frame 13 on the base 10, thus reducing the space occupied by the product and facilitating product transportation.

[0041] By adopting the above structure, the movable frame 13 moves up and down along the two first sliding rods 12, and the first display screen assembly 16 moves up and down along the two second sliding rails. This allows the movable frame 13 to move up and down relative to the upright frame 11, and the first display screen assembly 16 to move up and down relative to the movable frame 13, thereby increasing the range of movement of the first display screen assembly 16. This allows the third display screen assembly 19 to connect to the bottom of the first display screen assembly 16, thus improving the user experience. At the same time, by rotating the second display screen assembly 18 to the first display screen assembly 16, the first display screen assembly 16 and the second display screen assembly 18 can be placed on the same plane. This allows the first display screen assembly 16, the second display screen assembly 18, and the third display screen assembly 19 to form a large display screen, increasing the display area. Furthermore, the first display screen assembly 16 and the second display screen assembly 18 can be folded together to reduce the space occupied by the product, making it easier to store and transport.
