1. A flexible screen tensile test device, comprising a tensile unit, wherein the tensile unit comprises:
a rotating disk comprising rotating disk guide grooves;
telescopic slide rods positioned above the rotating disk and corresponding to the rotating disk guide grooves in a one-to-one correspondence, wherein the telescopic slide rods are annularly arranged to form a hollow ring column, a generatrix of the hollow ring column is perpendicular to the rotating disk, and an outer side wall of the hollow ring column is configured to support a flexible screen; and
sliding blocks connected with the telescopic slide rods and positioned in the rotating disk guide grooves;
wherein the rotating disk is rotatable within a predetermined angle to drive the telescopic slide rods to slide in a direction away from or close to a central axis of the hollow ring column and to cause a diameter of the hollow ring column to change.
