[0013] Compared with the prior art, the beneficial effects of the utility model are: the main control cover structure not only realizes the supporting and fixing functions, the partitioning function, but also realizes the disassembly and assembly function;

[0014] (1) By setting a limit plate, a main board and a fixed knife, the protruding part of the bottom of the fixed knife is placed in the inside of the placement groove, the limit plate is placed vertically on the top of the protruding part of the fixed knife, and the buckle is inserted and installed in the corresponding card hole at the bottom of the isolation rib. The limit plate is quickly installed and the fixed knife is limited and fixed at the same time. The isolation rib is used as a support, and the fixed knife and the main board are respectively fixed at the two ends of the isolation rib with a pressure strip. The fixed knife, the main board and the isolation rib are bound as a whole and can support each other, ensuring that the overall structure will not loosen or even move during use, enhancing the connection force between each other, not easy to deform, and reducing damage to the circuit;

[0015] (2) By providing isolation ribs and limiting grooves, the interior of the placement groove is horizontally fixed with isolation ribs to form an independent partition space, separating the fixed blade from the main board. The creepage distance is increased by the isolation ribs. When the fixed blade generates static electricity, it is not easy to be transmitted to the main board, thereby reducing the interference of metal parts to the wireless signal;
