Cable tensile property testing device

The invention relates to the technical field of tensile test devices, and discloses a cable tensile property test device which solves the problem that an existing tensile test device can only vertically stretch a cable, and the authenticity of test data is poorer in the mode, the cable tensile property test device comprises a base, and a mounting frame is fixedly mounted at the top of the base; a first rotating joint is fixedly mounted in the middle of the top of the base, a chest expander is fixedly mounted at the top of the first rotating joint, a first mounting cylinder is fixedly mounted at the top of the chest expander, first screw sleeves are fixedly mounted on the two sides of the first mounting cylinder, and first screw rods are in threaded connection with the interiors of the first screw sleeves; first hand wheels are fixedly mounted at the ends, away from each other, of the two first screw rods; according to the tensile test device, the cable can be stretched in multiple directions, and the authenti
