Stacking structure of integrated electric box

The utility model discloses a stacking structure of an integrated electric box, relates to the technical field of circuit board installation of the integrated electric box, and aims to solve the problems that the circuit board installation mode in the prior art is that a circuit board with a larger volume is installed at the bottom, then circuit boards with gradually reduced volumes are sequentially installed above, and once the circuit board at the bottom layer is damaged and needs to be overhauled, the circuit board is damaged. According to the technical scheme, the circuit board dismounting device is mainly characterized by comprising a mounting bottom plate, a plurality of first supporting rods and a plurality of second supporting rods are fixedly mounted on the upper surface of the mounting bottom plate, and the first supporting rods and the second supporting rods are arranged on the upper surface of the mounting bottom plate; a first circuit board is fixedly installed at the upper ends of the first supp
