The invention discloses a novel biaxial tensile test device, and relates to the field of tensile test devices, the novel biaxial tensile test device comprises a loading device, the top of the loading device is provided with a loading end sealing device, liquid, a first threaded hole, a tested piece, a second threaded hole, a sealing base, an observation area and a third threaded hole, four first threaded holes are formed in the bottom of the loading end sealing device, and liquid is arranged in the loading end sealing device. According to the invention, the male die stamping test is used as a template to build a basic model, a solid male die is changed into liquid, and a sample is stretched by hydraulic pressure, so that the consistency of loading and deformation in two directions in the test process can be ensured, and the friction force of a loading area can be reduced by using the characteristic of hydraulic pressure, thereby improving the accuracy of a test result and improving the test efficiency.
