Abstract: A direction-turning device for the lens of a camera phone is contained in a chamber extending between the front and rear sides of the camera phone, the chamber having front and rear openings each covered with a transparent window. The direction turning device includes a lens base fitted in the chamber having a lens in a sidewall of the lens base for shooting pictures, and a driving unit able to activate the lens base to rotate to let the lens to face toward the front side or the rear side of the phone through the transparent windows. Therefore, the invention is totally hidden in the chamber and able to optionally shift the lens to face toward the front side of the phone for self-shooting or the rear side of the phone for shooting normally.

Abstract: A direction-turning device for the lens of a camera phone contained in the rear side of the camera phone includes a lens base having a pivot at two sides respectively connected pivotally in an interior wall of the groove, a driving unit able to rotate the pivot for 180 degrees, and a positioning unit having an auxiliary gear fixed with the lens base and an elastic locking wire always stopping the auxiliary gear to keep the lens base positioned stably when moved to a position electronically or manually. The driving unit and the pivot of the lens base are linked by viscous oil, enabling the lens base driven by the driving unit or manually. The invention is totally hidden to keep the camera phone looked normally and able to shift the lens to face forward or backward with a self-shooting function.

Abstract: A sink trap having a generally semi-global main chamber, a shallow water chamber, a plurality of baffles for supporting the water chamber in the main chamber in an inwardly spaced relation and define a plurality of volute passageways between the main and water chambers and a cap detachably secured to the upper edge of the main chamber and an inlet pipe extending axially downwardly through the cap into the water chamber to lead drainage into the water chamber and discharging the drainage by overflowing the water chamber to flow through the volute passageways forming a turbulent liquid flow along a drainage pipe line to prevent the drainage pipe line from becoming choked with impassable matter.

Abstract: A space adjustment device of a blow torch comprising a tray, a retainer spaced from the tray for supporting a burner, an adjustable handle interconnecting the tray and the retainer, a ratchet mechanism fitted in the adjustable handle and used to prevent collapsing of the adjustable handle and a control unit associated to the ratchet mechanism and applicable to release the ratchet mechanism for a space adjustment between the retainer and the tray to fit a gas cassette of any of several standard sizes to the blow torch.

Abstract: An elongate plate having prealigned holes for guiding a flexible conduit in both the horizontal and vertical directions in order to form a flexible drain trap for permanently retaining a proper quantity of water therein to prevent an intrusion by insects.
