Abstract: A locking pliers includes a slide bar mounted in both second handle unit and locking unit and comprising a wavy edge facing bottom of the second handle unit, the wavy edge including a rear slot member and a forward hook; and a movable jaw at a forward end of the second handle unit and comprising two intermediate opposite stop members each having an inclined edge, a channel between the stop members with a forward end of the slide bar movably received therein, and a rear stop bar interconnected two sidewalls of a rear portion of the movable jaw, the inclined edges being stopped by bending members on sidewalls of the second handle unit for retaining the stop members in an inoperative position.

Abstract: A self-adjusting locking pliers includes a stationary handle; a front stationary jaw; a thumb screw threadedly secured to a rear end of the stationary handle; a front moveable jaw; an operating handle pivotably secured to a rear end of the moveable jaw; a toggle link pivotably interconnecting the stationary handle and the operating handle; a biasing member having one end secured by the moveable jaw and the other end fastened in the stationary handle; a quick release lever having an intermediate portion pivotably fastened in the operating handle and a front end urged against one end of the toggle link in the operating handle; and a retainer having one end pivotably secured to a rear end of the operating handle, the retainer comprising a ring at the other end and a bar interconnecting both ends. The ring may be lockingly put on the thumb screw.

Abstract: A lifting device includes two opposite parallel rings; and a bridge member interconnecting the rings, the bridge member comprising a through hole having a diameter greater than that of a threaded shank of a thumb screw. Threaded shank of the thumb screw is adapted to drive through the through hole into a threaded hole in a rear end of a stationary handle of a self-adjusting locking pliers to rotatably retain the lifting device.

Abstract: The present invention relates to a pharmaceutical composition for inhibiting influenza virus infection and reproduction, comprising a effective amount of C-phycocyanin (C-PC), allophycocyanin (APC), spirulina growth factor (SGF) or the mixture thereof. The present invention also provides a method for extracting said pharmaceutical composition, comprising the steps of: (a) adding hypotonic buffer solution to organic blue-green algae powder and mixing thoroughly; (b) incubating the mixture below room temperature overnight; (c) separating and purifying the mixture by a centrifuge; (d) collecting the suspending supernatant and detecting it by a spectrometer to determine ingredients and content; and (e) spray drying the supernatant; characterized in which low-temperature extraction is employed to maintain the bioactivity and nutrients of the pharmaceutical composition.
