[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By providing a card slot, a docking slot and a positioning docking plate, the card plate enters from the opening position of the card slot and presses the pressure plate upwards. When the pressure plate moves upwards, the card plate is completely entered into the card slot and is pressed by the spring. The pressure plate presses the card plate downwards to press it to the bottom of the card slot and staggered with the entrance. This can prevent the card slot from being separated from the card plate. The pressure plate presses the card plate with the spring to stabilize the card plate. When removing it, the above method can be reversed. The display screen body is connected to the positioning docking plate in a card connection manner for easy installation and removal, which solves the problem that the installation and removal of the existing full-color LED display screen requires bolt installation, which increases the installation steps.
