FIELD: the invention refers to measuring technique. ^ SUBSTANCE: it may be used for measuring of the sizes of the lines on curvilinear or volumetric surfaces particular in criminology, medical jurisprudence, archeology, zoology etc. particularly if there is necessity of photo fixation of these sizes. The rule is fulfilled out of thin spring stainless steel with lusterless surface on which a millimeter marking is outlined. The ends of the rule are turned up in the shape of semicylindrical surfaces forming immobile jaws. Besides mobile jaws are fixed on the ends of the rule. They are fulfilled out of plates which are turned up in the middle part in the shape of a semicylinder. Their coming forward ends are turned up towards the immobile jaws. The technical result is that the rule makes it possible to make factual measuring and detail scale photo fixation without hotspots on the scale rule traces of crimes and corporal injuries on any curvilinear of the surface of the investigated object including the human body even in vertical position at the expense of mobile and immobile jaws. The arrangement is lasting, does not deform with time, is easily sterilized, simple in construction, comfortable in using even in field conditions. ^ EFFECT: the arrangement increases the quality of measuring. ^ 1 dwg |
