An external thread pipe is inserted in an internal thread pipe and screwed in the internal thread pipe through threads. The upper end of the external thread pipe is fixed to the lower side wall of a motor shell. A motor rear cover is arranged on the upper side of the motor shell. A protrusion on the lower surface of the motor rear cover is embedded in an opening in the upper side of the motor shell. A magnetic ring rear cover is arranged on the lower side of the center of the motor rear cover. A protrusion on the lower side of the magnetic ring rear cover is embedded in a column body at the center of a stator. The center of the lower surface of the magneticring rear cover is screwed at the upper end of a stainless steel shaft through a bearing. The lower end of the stainless steel shaft is inserted and fixed into the center of an impeller. A magnetic ring sleeves the outer sid
