FIELD: testing equipment.
SUBSTANCE: clamping device comprises body with mechanism of sample compression, two clamping grips. Body is arranged in the form of arched basic and attachable beams, with ledges arranged on their internal working surfaces. On internal working surface of basic beam there are fixed pins installed, which are movably arranged in guide holes provided in attachable beam. Each pin is equipped with detachable clamping pin. Pins and clamping nuts compose mechanism of sample compression. Upper and lower detachable clamping grips are arranged in the form of semicircle, straight edge of it is arranged in the form of collar. Collar of lower clamping grip is directed to the side of basic beam, and collar of upper clamping grip is directed to the side opposite to basic beam. In plane of lower clamping grip through its convex edge there are the following components arranged perpendicularly to collar: through middle indent that touches collar, and parallel on its both sides there are through side indents for location of basic beam pins in it. In plate of upper clamping grip there are through template holes arranged. Near convex edge of plate there are location holes arranged for installation of basic beam pins, and in middle part of straight edge through collar there is a bore arranged with aligning lines arranged on its edges.
EFFECT: invention provides for possibility to detect parametres of sample tension in any directions in respect to vector of stretching force, which is locally applied to plate of tested sample, and increased convenience in preparation for testing of biological tissue sample.
