Annular specimen tensile testing device and realizing method thereof

The invention discloses an annular specimen tensile testing device and a realizing method thereof. The annular specimen tensile testing device comprises tensile equipment, a first connection joint, a second connection joint, a first connection plate, a second connection plate, a first separation disc, a second separation disc, an annular specimen, a first equipment bolt, a second equipment bolt, a first connection bolt, a second connection bolt, a first fixing bolt, a second fixing bolt, a first limiting bolt and a second limiting bolt. The annular specimen tensile test device has the advantages that the structure is simple, and the design is scientific and reasonable; compared with the traditional tensile disc which is customized to different annular specimens, the device is suitable for performing tensile test on the annular specimen with multiple modulus diameters, the suitability is strong, and the repeated utilization is realized; the connection structure of the parts is simple, the force transfer path i
