Conversely, the circuit board 20 may be detached from the case 10. Therefore, through two working modes of front disassembly and rear disassembly, the flexibility of disassembling and assembling the circuit board 20 is improved, and the circuit board is easy to maintain. Therefore, the technical scheme of the embodiment effectively solves the problem that the circuit board cannot be flexibly maintained due to single front installation or single rear installation in the related technology.
