Abstract: A decorating glass vessel is disclosed. In particular, It relates to a spherical shape decorating vessel filled with water. The glass vessel is disposed with an opening which has extended with a circular wall upward to a preset height. A soft cover can be inserted into the circular wall such that a frictional engagement is attained between the circular wall and the cover. The water facing surface of the cover is provided with an elevated surface. The other portion of the water facing surface except the elevated surface is provided with at least one thinner portion with thinner thickness. The thinner portion can be readily deformed to absorb the increased hydraulic pressure resulted from temperature gradient. Consequently, the water or air leakage resulted therefrom can be therefore avoided.

Each curved arm has a pair of horizontally outwardly arched sections, a horizontally inwardly curved section connected between the horizontally outwardly arched sections, and a coupling tip at a free end. The clamping strip has a retainer portion at its free end for securing the coupling tips of the curved arms together. The clamping strip also has a plurality of downwardly curved sections and upwardly curved sections alternatively connected in a line between the clamping strip fixed end and free end. The width of the clamping strip is broader than the gap between the horizontally inwardly arched sections of the curved arms.

Abstract: A tripod including a tripod head supported on tripod legs and formed of two symmetrical half shells and defining a ball socket between the half shells, a camera platform adapted for holding a camera and having a ball at the bottom mounted in the ball socket of the tripod head, a hexagon nut mounted within a hexagonal hole in one half shell of the tripod head, a lock screw inserted through a respective mounting hole in each half shell of the tripod head and threaded into the hexagon nut and then screwed up with a cap nut, wherein turning the lock screw in one direction causes the two half shells of the tripod head to be released from each other for permitting the ball of the camera platform to be turned to the desired angle; turning the lock screw in the reversed direction causes the ball of the camera platform to be firmly retained in the ball socket of the tripod head in position.

Abstract: 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.

Abstract: The present invention relates to a keyboard switch which comprises first and second elements alternately engaged with each other and supporting a keycap at the top ends of the elements. The inner edges of the first and second elements are each respectively provided with a corresponding pressing board. The external edges of the first and second elements are provided with a corresponding protruded shaft and a slot to enable restricted movement. When the keycap is pressed at any position, due to the restricted movement, the keycap will move downwardly with a well balanced and stable motion along a shortest distance path to trigger the electrical contact assembly located below when the keycap; when the keycap is released, it will be restored to its original position as a result of a force exerted by an elastic rubber pad mounted within a keyseat.
