Macro-bending test tool for optical fiber

The utility model provides a macro-bending test tool for optical fibers, which enables rapid macro-bending test to be carried out by adjusting the interval between upper and lower rows of bearings after the optical fibers are linearly arranged, so that the test efficiency is high, and the requirement of rapid macro-bending test is met. The upper surface of the bottom plate is provided with at least one first row of bearing groups which are convex upwards; the upper surface of the upper plate is provided with at least one group of upward-convex second-row bearing groups, the upper plate is provided with waist-shaped holes corresponding to upward-convex bearing positions of the first-row bearing groups, the length direction of the waist-shaped holes is the Y direction, the length direction of optical fibers is the X direction, and the X direction is perpendicular to the Y direction; the upper plate is arranged right above the bottom plate; and the corresponding first row of bearing groups and second row of bear
