During repeated tests, the device may break the fiber, which may cause the accessories to fly out and injure people. In addition, the fiber is thin during bundling and observation, and supplementary light is required for observation. However, the angle of the supplementary light is not easy to adjust, which affects the applicability of the device. Therefore, the prior art needs to be improved. Utility Model Content

[0013] 2. The utility model adds structures such as a mounting frame, a rubber strip and a fill light to the test machine. During use, the angle of the fill light can be adjusted by the angle between the mounting frame and the test machine, so that the fill light can fill light to the installation position at multiple angles, making the device easier to use. The friction between the rubber strip and the mounting frame limits the use angle of the mounting frame, making the fill light more stable after adjustment. BRIEF DESCRIPTION OF THE DRAWINGS
