A MECHANICAL JOINT STRUCTURE

摘要

A joint (100) arranged to interconnect two elements (102, 104) to allow relative movement to those elements, the joint comprising a first member (102) operative to be connected to one of the elements and a second member (104) operative to be connected to the other element, the second member (104) being coupled to the first member (102) so as to be movable relative to the first member (102) about a first axis, wherein the second member (104) includes first and second parts that are movable relative to each other about a second axis that intersects the first axis so as to allow the joint to rotate through two rotational degrees of freedom around a common point.
