[0009] Preferably, a threaded groove is formed on one side of the inner tube, a slot hole is formed on one side of the housing, and one end of the liquid taking faucet is rotatably connected to the threaded groove formed on the inner tube through the slot hole formed on the housing.

[0010] Preferably, threaded rings are inserted inside both sides of the outer shell surface. One end of each threaded ring is internally connected to a compression spring. One end of the compression spring is connected to a movable rod. One end of the movable rod is movably connected to a positioning plate. Both sides of the positioning plate are movably connected to second bearings.

[0011] Preferably, the second bearings are connected to one side of the inner surface of the outer shell. The outer shell and the positioning plate are movably connected by the second bearings. The positioning plate is sleeved on one side of the outer surface of the inner tube.
