Abstract
A clamping device includes elongated first and second butt housings that are connected pivotally to each other and that have free ends, which are locked relative to each other by a releasable locking unit. Two aligned first large notches in two side walls of the first butt housing and two aligned second large notches in two side walls of the second butt housing constitute a confining hole unit that is adapted to permit extension of an article. Elastic first and second pressing elements are disposed respectively within the first and second butt housings, and are adapted to clamp the article therebetween.
Claims11
A clamping device comprising:

- an elongated second butt housing having a pivot end connected pivotally to said pivot end of said first butt housing, a free end, a base wall, and two side walls extending respectively from two opposite sides of said base wall of said second butt housing to define an interior space among said base wall and said side walls of said second butt housing, each of said side walls of said second butt housing having an inner side that abuts against said inner side of a corresponding one of said side walls of said first butt housing and that is formed with a second large notch which is aligned with said first large notch in said first butt housing, said first large notches in said side walls of said first butt housing and said second large notches in said side walls of said second butt housing constituting cooperatively a confining space unit between said first and second butt housings, said confining space unit being adapted to allow for extension of an article therethrough;
- an elastic second pressing element attached fixedly to said base wall of said second butt housing and disposed within said interior space in said second butt housing between said second large notches in said side walls of said second butt housing, said first and second pressing elements being adapted to clamp the article therebetween;
- and
- a releasable locking unit interconnecting said free ends of said first and second butt housings so as to lock the first and second butt housings against each other, said locking unit being operable to unlock said first and second butt housings from each other;
- wherein said base wall of said second butt housing has an outer surface that is formed with a paper clip unit, said paper clip unit including an elongated flexible plate that is generally parallel to and that is adjacent to said outer surface of said base wall of said second butt housing and that has a connecting end attached fixedly to said outer surface of said base wall of said second butt housing, and a free end which is adapted to press a paper sheet against said outer surface of said base wall of said second butt housing;
- and
- wherein said free end of said flexible plate is formed with a first projection and a second projection that is spaced apart from said first projection and that is disposed between said connecting end of said flexible plate and said first projection, said first and second projection pressing against said outer surface of said base wall of said second butt housing and adapted to press the paper sheet against said outer surface of said base wall of said second butt housing.

- and
- a clamping unit, which includes:
- a mounting seat disposed fixedly on an outer surface of said base wall of said first butt housing and having a clamping portion and a U-shaped bracket portion that has two aligned side plate portions, each of which is formed with a slide slot extending along a direction generally perpendicular to said outer surface of said base wall of said first butt housing;
- an elongated zigzag reed spring having a connecting end fastened to said mounting seat, and a free end;
- and
- an L-shaped rotating plate including a long plate portion having an inner end disposed between said side plate portions of said U-shaped bracket portion of said mounting seat, and an outer end abutting said free end of said reed spring and adjacent to said clamping portion of said mounting seat, a short plate portion extending perpendicularly to said long plate portion and having an inner end formed integrally with said inner end of said long plate portion, and an outer end contacting said reed spring, and two pivot pins extending outwardly from said inner end of said short plate portion away from each other and received respectively and slidably within said slide slots in said mounting seat, said outer end of said short plate portion contacting said reed spring at a location such that said reed spring biases said long plate portion to rotate toward said clamping portion of said mounting seat, said outer end of said long plate portion of said L-shaped rotating plate and said free end of said reed spring being adapted to press a laminated element against said clamping portion of said mounting seat.
