| 摘要 |
The invention relates to a lifting clamp (1) for mounting in a housing of an electrical appliance, e.g. a circuit-breaker, comprising a rectangular frame (14) and a rectangular box (15), the upper section (150) of said box being arranged between the upper section (140) and the lower section (141) of the frame (14), enabling the box (15) to be held in the frame (14) in a displaceable manner. Said lifting clamp also comprises a clamping screw (16) which is guided through an opening (142) incorporated in the upper section (140) of the frame in a freely rotatable manner, and which engages in a screw thread (152) incorporated in the upper section (150) of the box (15). Said box (15) is held in the frame (14) against a resistance in a displaceable manner. |
