PURPOSE: A specimen fixing device of a tensile testing device is provided to prevent a grip unit of an ultra thin specimen in a testing process by firmly fixing the specimen. CONSTITUTION: A specimen fixing device(10) of a tensile testing device comprises a pair of fixing units(12). The fixing units fixing both front ends of a specimen respectively are oppositely arranged, thereby being mounted in the tensile testing device. The fixing unit includes a body(14), a fixing bar(16), and a pressing member(18). The body is mounted in the tensile testing device. The fixing bar is installed in the body in a width direction of the specimen and has a structure of a circular cross-section in which one front end of the specimen is wound. The pressing member is joined in the outer side of the fixing bar, thereby fixing the specimen by pushing. |
