On the other hand, it is difficult for traditional testing equipment to adjust the test strength flexibly, making it difficult to meet the diversified testing needs of different strength glass fibers. Therefore, the present application provides a fiber strength tester to meet the needs. SUMMARY

[0012] Optionally, the extrusion rods are circumferentially and equidistantly distributed on the inner side of the test table, and one end of the extrusion rod extending to the inner side of the mounting wheel is rotatably connected with a clamping wheel.

[0013] Compared with the prior art, the utility model has at least the following beneficial effects:
