In addition, when conducting the test, the protective cover 15 can be pushed so that the protective cover 15 can protect the area of ​​the communication cable tensile test to avoid injuring the staff when the communication cable is broken and burst out; and in order to simulate the tensile resistance of the communication cable when it is swung by external influences, the first The second driving member 1103 drives the second gear 1102, and the meshing first gear 1101 can drive the annular cylinder 9 to rotate, and then drive the rotating frame 1203 to rotate with the annular cylinder 9.

[0040] The present invention provides a tensile strength test device for a communication cable. The end of the communication cable to be tested is fixed by a clamping component 5, and the communication cable is passed through an annular cylinder 9. Then, a moving component 4 is driven by a power component 6, and the moving component 4 drives the clamping component 5 to move outward, thereby applying a tensile force to the communication cable, and then the tensile strength of the communication cable is tested.
