Power supply multilayer circuit board

The utility model discloses a power supply multilayer circuit board, comprising a board body, two ends of the board body are connected with bases, the front and rear surfaces of the bases are fixedly provided with installation feet, and the installation feet can be fixed with an external installation surface through screws subsequently, thereby realizing installation of the board body, preventing extrusion and wear of the board body when the screws are installed, and improving the reliability of the board body. A dismounting mechanism is arranged between the base and the plate body; according to the power supply multi-layer circuit board, the bases, the mounting feet and the dismounting mechanism are arranged, so that when the power supply multi-layer circuit board is mounted, the two bases can be connected with the board body firstly, and then the mounting feet on the bases are directly fixed with a mounting surface through screws, so that the quick mounting of the power supply multi-layer circuit board can
