A drop-bottle stand includes a base, a lower connecter, an outer tube, an inner movable tube extending and movable in the outer tube, an adjusting sleeve, a lower connecter, a cylindrical member, an upper connecter, a top hanging bar, an eccentric arm, and a plate. The inner movable tube can be moved up and down relative to the outer tube so as to adjust the height of the hanging bar by means of the eccentric arm, which can be swung to release or compress the plate and then the inner movable tube so as to free or tighten unmovable the inner tube for adjusting its position. The outer tube and the inner tube all have two opposite grooves to engage with each other to prevent the inner movable tue from moving rotatably.

[ What is claimed is:] [1.] A drop-bottle stand comprising:a base consisting of two horizontal elongate plates crossing with each other at respective center portions thereof, each of said elongate plates having a centrally disposed aperture, said elongate plates being connected with a screw passing through said apertures, each said elongate plate having a wheel combined with each of two ends to roll freely on the ground;a lower connecter having a cylindrical shape and having an open upper side and a lower side with a small center hole formed therein for said screw to pass therethrough from below said base;an outer tube having female threads formed in a bottom end thereof, said bottom end being disposed in said lower connecter for engaging said screw to secure said outer tube and said lower connecter to said base, said outer tube having two longitudinal grooves formed in an outer surface of opposing sides thereof and a rectangular hole formed therethrough, said two longitudinal grooves forming two longitudinal projections on an inner surface of said outer tube;an adjusting sleeve having (a) an inner protruding edge formed in an upper end thereof, (b) a centrally disposed hole extending longitudinally therethrough, (c) a pair of longitudinally spaced ears respectively formed adjacent said upper end and a lower end thereof, said pair of ears being positioned in line and each having a vertical hole formed therethrough, (d) a recessed opening located between said pair of ears, (e) a plate having an outer concave surface and a central vertical ridge formed on an inner convex surface and positioned within said recessed opening, (f) an eccentric arm disposed between said pair of ears and having an eccentric portion with a vertical hole formed therein, said vertical hole of said eccentric portion being in aligned relationship with said vertical holes of said pair of ears, and (g) a pin inserted through said vertical holes of said pair of ears and said vertical hole of said eccentric portion of said eccentric arm, said eccentric arm being rotatable through 90 degrees for selective engagement or disengagement of said eccentric portion with respect to said concave surface of said plate, and said adjusting sleeve being fixedly attached to an upper end of said outer tube;an inner movable tube telescopically disposed within said outer tube and having two longitudinal grooves formed on opposing sides thereof engaged with said two longitudinal projections of said outer tube, said inner movable tube having a positioning hole formed through a side wall thereof;a cylindrical member having a hole formed centrally therethrough and an inwardly protruding edge formed in an upper end thereof, said cylindrical member having a slot formed in an lower side thereof, a vertically directed recess, fixedly attached to said upper end of said outer tube, and for guiding the inner movable tube within the outer tube;a two-piece ring having two semicircular pieces respectively provided with a projection extending from an inner surface thereof, disposed within the outer tube and for interlocking with the inner movable tube;a cylindrically shaped upper connecter having a closed upper end and an open lower end, said upper connector having an aperture formed through a side wall thereof, said closed upper end having a transversely directed groove formed therein and a top hanging bar positioned in said transverse groove and secured therein, said hanging bar having a hook formed on each end thereon, said open end of said upper connecter is fitted around an upper end of said inner movable tube; and,an elastic button formed by a button body and an elastic U-shaped member having one end connected to said button body, said U-shaped member being completely inserted in said upper end of said inner movable tube, said button body extending out through said positioning hole of said inner movable tube for a predetermined distance established by a flange formed in an inner side of said button body and passing through said aperture of said upper connector to prevent said inner movable tube from rotating, and said flange being of larger diameter than said positioning hole of said inner movable tube.
