摘要
A swivel joint for a hand-held vacuum cleaner includes a first joint tube and a second joint tube rotatably connected at one end portions thereof with respect to each other, a connecting tube enabling communication between the first joint tube with the second joint tube, and a conductive assembly. The connecting tube is a corrugated flexible tube. The other end portions of the first and second joint tubes respectively connect a vacuum cleaner body with a dust suction tube of a vacuum cleaner or the dust suction tube with a dust suction head of the vacuum cleaner. The conductive assembly includes a first conductive interface and a second conductive interface respectively disposed on the first and second joint tubes and a conducting wire disposed inside the corrugated flexible tube. Two ends of the conducting wire connect with the first and second conductive interfaces, respectively.
