The inner wall side of the fixed pipe 25 is provided with an internal thread, and the outer side of the external threaded pipe 23 is fixedly connected to an internal threaded pipe 24 that is threadedly connected to the fixed pipe 25.

[0027] When the outer end cover 1 is in contact with the first inner end cover 11, the external threaded tube 23 is twisted into the slot 5. The external threaded tube 23 drives the internal threaded tube 24 to connect with the inner wall of the fixed tube 25. At the same time as the external threaded tube 23 and the internal threaded tube 24 are connected, the outer end cover 1, the first inner end cover 11 and the second inner end cover 12 are connected. The external threaded tube 23 and the fixed tube 25 are used to dissipate heat inside the motor. The filter screen set on the inner wall of the fixed tube 25 blocks debris. The connection of the external threaded tube 23, the internal threaded tube 24 and the fixed tube 25 facilitates the splicing and disassembly of the outer end cover 1, the first inner end cover 11 and the second inner end cover 12.
