More Information
Summary:A clamping apparatus of construction molding board has a base, a base body, a press bar, and a torsion spring. The base is provided with a through hole. The base body of U-shaped construction is made integrally with the base such that the base body extends upwards from the base. The base body contains a receiving space having a rear portion provided with a canal in communication with the through hole of the base. The press bar has a bottom end provided thereon with a serrated arresting portion. The press bar is mounted pivotally in the receiving space by a shaft pin in such a manner that the arresting portion is opposite in location to the canal. The torsion spring is composed of two ring bodies sharing a common end which forms a pressing portion of an inverted U shape. The two ring bodies are provided respectively with another end which forms a supporting portion. The torsion spring is mounted in the receiving space such that the two ring bodies are fitted over the shaft pin, and that the pressing portion embraces the press bar, and further that the two supporting portions are sustained at a predetermined location.
