The utility model relates to a novel testing apparatus which determines the tensile fatigue strength to the elastic material specimen, and the novel testing apparatus is formed by that a power transmission system and a specimen testing frame are arranged together in an outer box body, and the novel testing apparatus is also provided with an automatic counting, printing, displaying and controlling system; the specimen testing frame is formed by two fixing beams which are respectively installed horizontally on the upper end part and the lower end part of two vertical post sliding rails which are arranged vertically, and when a sliding beam group is horizontally installed on the middle part of the vertical post sliding rails by sliding cooperation, a plurality of specimens are uniformly divided into two groups and respectively clamped in each pair of specimen clamping heads of the upper and the lower groups which are arranged on the front side of three beams, and the specimen clamping head which is hinged on the fixing beams can automatically turn over and alarm after the specimen is cracked.
