ADJUSTABLE DEVICE WITH UNIVERSAL JOINTS

摘要

An adjustable device is disclosed comprising two relatively re-orientatable members each having a lockable universal joint, and a connecting member for connecting the two relatively re-orientatable members whereby when the two relatively re-orientatable members are connected the two joints are in mechanical communication via the connecting member. The two lockable joints may be locked and unlocked using an actuator, a lever, which may act on a compression device in order to render the lockable joints either mobile or locked. The compression device may cause a change in cross-sectional area of the tube over at least a part of its length. At least one of the lockable universal joints may provide for linear movement between the two relatively re-orientatable members. Also disclosed is an apparatus for the simulation of the orientation of a sample with respect to a cutting tool or scanning probe and method for aligning the adjustable device.
