The operation is cumbersome and labor-intensive, and both sides of the data cables cannot be clamped at the same time. It is also difficult to determine the clamping pressure. The clamping end of the data cable may easily fall off during the tensile test, which is not conducive to user analysis and testing. Utility Model Content

[0010] Beneficial Effects

[0011] The utility model provides a tensile force testing device for data cables. Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) The tensile test device for data cables is provided with a drive shaft assembly and a clamping member in the device. When the two sides of the data cable are placed on the inner ends of the two sets of clamping members, the two sets of bidirectional screws are driven to rotate by a micro motor, two sets of bevel gear assemblies, a drive shaft, and a driven shaft. The two sets of bidirectional screws respectively drive the two sets of clamping blocks to clamp the two sides of the data cable, thereby achieving synchronous positioning of the two sides of the data cable, simplifying the installation steps.
