Due to its advantages of high definition, customizability, reliability, energy saving and environmental protection, it can be used in various occasions, such as commercial advertisements, sports events, concerts, exhibitions, etc. When installing the LED splicing screen, multiple separate display screens will be installed on the display bracket.

[0003] However, traditional LED splicing display screens are mostly installed and fixed by multiple bolts to a single LED display screen. Therefore, when one of the LED display screens is damaged and needs to be disassembled, multiple bolts need to be twisted to disassemble the LED display screen, which wastes a certain amount of time and is inconvenient for the inspection and maintenance of the LED display screen. In addition, during the disassembly process, the LED display screens next to the LED display screens will also block the body of the staff. At the same time, since the space between two adjacent LED display screens is small, collisions and jams are prone to occur during the operation, resulting in poor convenience of operation. Utility Model Content

[0024] As a technical optimization solution of the utility model, the base plate 1 is provided with a plurality of mounting holes 4, and the plurality of mounting holes 4 on the same side of the base plate 1 are linearly and equidistantly distributed, so that the base plate 1 can be installed and fixed by means of the mounting holes 4 in conjunction with bolts.

[0025] As a technical optimization scheme of the utility model, the pushing structure 2 includes a double-headed motor 201, and the double-headed motor 201 is installed on the base plate 1. Two screw rods 202 are rotatably connected to the base plate 1, and the two ends of the double-headed motor 201 are respectively fixedly connected to the two screw rods 202, and the screw rods 202 are threadedly connected with a push rod 203. A connecting shaft 205 is rotatably connected to the connecting plate 5. A plurality of connecting shafts 205 located on one side of the push rod 203 pass through the push rod 203 and are rollingly connected to the push rod 203.
