    摘要: An instrument for measuring positions and displacements of portions of a human body, comprising a base plate and a belt or suction cup for detachably securing the base plate to a portion of a human body. A bifurcated holder is mounted on the base plate for rotation about a first axis, the bifurcated holder having a pair of arms, and a housing is pivotally carried between these arms for swinging movement about a second axis perpendicular to the first axis. A dip circle and a north-south-seeking compass are carried by this housing, the dip circle and compass being mounted on the housing for pivotal movement about a common third axis perpendicular to the second axis. The base plate has a scale thereon, and there is an indicator on the holder for indicating on the scale the degree of rotation of the holder relative to the base plate. There is also a scale for indicating the degree of rotation of the dip circle and compass relative to the housing, and this scale is rotatable relative to the housing about that common third axis.
