[0002] As an output device, display screens are widely used in various electronic products to intuitively present images, text, videos and other information.

[0003] The split display screen breaks through the integrated design of traditional display screens and separates the display screen module from the device body, which brings unique advantages and diversified applications. For example, each module can be upgraded independently. For example, if the display screen technology is updated, only the display screen needs to be replaced. If the performance of the signal processing unit and the power module meets the requirements, they can continue to be used, saving costs and extending the overall service life of the equipment.

[0004] The display angle of existing split display screens is usually adjusted within a small range, and thus cannot meet the viewing needs of users in different positions.

[0009] Through the above technical solution, the first motor is started to drive the second gear to rotate, and the rotation of the second gear drives the first gear and the first rotating shaft to rotate.

[0010] Furthermore, the top end of the first rotating shaft is fixedly connected to the top wall of the second supporting column, a movable cavity is opened in the second supporting column, the movable through groove penetrates the top wall of the second supporting column and is connected with the movable cavity, a bidirectional threaded rod is arranged in the movable cavity, both ends of the bidirectional threaded rod are respectively rotatably connected to the side walls of the second supporting column, and clamping clamps are respectively rotatably connected on both sides of the bidirectional threaded rod, and the top end of the clamping clamp is inserted in the movable through groove.

By pulling the limit column, the movable push-pull rod is retracted into the connecting box body. At this time, the display screen body or the mobile tablet computer is placed on the surface of the support plate, and the limit column is released.

The split movable LED display screen according to claim 7, characterized in that: The limit locking mechanism (5) comprises a connecting box body (501), a movable push-pull rod (502) is slidably connected between the top wall and the bottom wall of the connecting box body (501), the movable push-pull rod (502) is arranged in sequence along the bottom wall of the connecting box body (501), the top end of the movable push-pull rod (502) is fixedly connected to a push-pull plate (503), the top wall of the push-pull plate (503) is fixedly connected to a limit column (505), the outer wall of the limit column (505) is sleeved with a spring (504), and the two ends of the spring (504) are respectively located between the top wall of the push-pull plate (503) and the top wall of the connecting box body (501).

9. A method for using a split mobile LED display screen according to any one of claims 1 to 8, characterized in that: The method for using the split mobile LED display screen comprises the following steps: The first step is to pull the limiting column (505), place the display screen body on the surface of the support plate (406), loosen the limiting column (505), and under the elastic force of the spring (504), the push-pull plate (503) drives the movable push-pull rod (502) to extend out of the connecting box body (501), and at this time, the movable push-pull rod (502) can establish a limiting relationship with the edge of the display screen; The second step is to start the third motor (409), at which time the steering shaft (410) rotates, and the steering shaft (410) drives the support plate (406) to rotate around the engagement point with one end of the movable limit plate (405) through the first connecting rod (412) and the second connecting rod (411), thereby adjusting the display angle of the display screen; The third step is to start the second motor (308), the output end of the second motor (308) rotates, driving the transmission worm (303) to rotate, the transmission worm (303) rotates, driving the fourth gear (310) to rotate, and the annular flange sleeve (304) starts to make a linear motion along the first rotation axis (302). When the annular flange sleeve (304) makes a linear motion along the first rotation axis (302), it drives the third gear (313) to start rotating, thereby realizing the rotation of the bidirectional threaded rod (312), and the clamping forceps (314) clamp the outer wall of the angle adjustment mechanism (4) through the rotation of the bidirectional threaded rod (312); The fourth step is to start the first motor (307), the first motor (307) drives the second gear (306) to rotate, and the rotation of the second gear (306) drives the first gear (305) and the first rotating shaft (302) to rotate, thereby realizing the change of the display angle of the display screen.
