| 摘要 |
The invention relates to an adjustable fastening device e.g. for an axially-shaped, tubular, flat or spherical tool or working piece or machine part or a like of a desired shape. The device includes: a body section (1), a clamping means (2), mounted within the body section (1) and at least partly pressable/squeezable indirectly or directly against a piece (10) to be fastened. Between the body section (1) and the clamping is provided a space (3), which is pregreased for a medium effecting said pressing/squeezing. The medium comprises in situ cast elastomer (5) whereby, upon the application of pressure on elastomer by means of a screw, a piston or the like, said elastomer (5) delivers by way of its displacement and/or deformation said pressure to clamping means (2) which thus presses/squeezes against a piece (10) to be fastened and, upon releasing said pressure, the elastomer (5) returns to its initial state.
