▎ 摘　　要

NOVELTY - Board comprises a main plate component (3) whose two sides are provided with a locating component (5). A screw rod is rotatably set on the main plate component. One end of a screw rod nut is provided with a location column. A compression block is slidingly set on the main plate component. The compression block is located below the location column. A bottom of the compression block is connected with a connecting rod. The location column moves and compresses the connecting rod. A lifting component is provided between the connecting rod and the compression block. The lifting component is set on the main plate component, when the compression block is downward. An elastic lifting component stores an elastic compression force. USE - Mobile phone main board with good radiating effect based on graphene. ADVANTAGE - The mobile phone main board has good radiating effect based on conduction graphene. The main board component is fast fixed on the machine frame, and the size difference of the main plate components can be fixed on machine frame. The use scene of main board is increased. The convenience of the current main board when installing and reducing the damage condition when the main plate component is installed is greatly improved. The efficiency of the personnel maintenance screen assembly or main board can be accelerated. The maintenance efficiency of maintainer can be improved. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the mobile phone main board with good radiating effect based on graphene. 1Machine frame 2Screen assembly 3Main plate component 4Graphene layer 5Locating component 31Groove
