[0019] The rotating guide drive assembly includes guide grooves 16 symmetrically opened on both sides of the inner wall of the cavity, and the guide grooves 16 include a lower vertical part 161 and an upper arc-shaped part 162 bent to one side, and the guide sliders 17 are fixedly installed at the corresponding guide groove positions on both sides of the lower fixed part of the elastic telescopic tube. The guide sliders 17 slide in cooperation with the corresponding guide grooves. When the electric telescopic rod contracts, the docking tube moves up, and first the upper telescopic part of the elastic telescopic tube docks with the docking joint, and then the lower part of the elastic telescopic tube continues to move up. Under the cooperation of the guide slider and the guide groove, the docking tube will rotate, and the docking joint will be driven to rotate synchronously. At this time, the butterfly valve plate rotates to open the seal of the first vertical tube through the meshing cooperation of the gear and the gear ring.
