The first shell and the second shell are connected by the assembly block and the assembly slot. When installing, the assembly block on the top of the first shell The card block is inserted into the assembly card slot at the bottom of the second shell and fixed with a fixing bolt. When disassembling, you only need to remove the fixing bolt to separate the first shell and the second shell, which is convenient for quick inspection and maintenance of the internal micromotor body. However, the micromotor still has the following defects during use: the micromotor can indeed be easily spliced ​​and fixed by bolts through the first shell, assembly card slot, second shell, fixing bolts and assembly card blocks, but the micromotor fixed by bolt threads is inconvenient to disassemble.
