摘要

A clamping device (10) for fastening an article, such as a lamp or a support for a computer terminal, comprises a frame member (11) having surfaces engaging with the upper surface of a table top (15). A pair of arms (18) are swingably mounted around a stud or shaft (16) extending downwards from the frame member (11). Screw members (21) mounted at the free ends (23) of the arms (18) and provided with replaceable abutment members (24) at their free ends may be screwed into engagement with the bottom surface of the table top (15). The arms (18) may be moved upwards along the shaft (16) by means of a nut member (19), and by adjusting the mutual angular position of the arms (18), the abutment members (24) may be placed in a suitable position at the bottom surface of the table top.
