The rubber sealing ring body and the rubber sleeve end are squeezed and deformed by both the second connecting tube and the docking sleeve, thereby increasing the sealing effect between the second connecting tube and the docking sleeve. At this time, the stress ring drives the positioning plug rod to be inserted into the inside of the positioning plug hole under the elastic force of the positioning spring, thereby achieving fixed installation between the second connecting tube and the docking sleeve; when the rubber sealing ring body needs to be removed, the positioning plug rod is pulled away The rubber sealing ring body can be removed from the butt joint sleeve by pulling the second connecting tube away from the positioning socket and releasing the fixation between the second connecting tube and the butt joint sleeve.
