[0002] Cable detection is mainly to timely detect abnormal conditions occurring during the operation of cables to ensure the continuity and reliability of power or signal transmission.

[0003] A Chinese patent with the application publication number CN219015280U discloses a cable stretching deformation detection device. In this patent, a rack is connected to the bottom of a clamping plate through a connecting block, and the clamping base is arranged to be adjustable along its central axis direction, so that the distance between the clamping plates can be adjusted, and thus two clamping mechanisms located on both sides of the detection mechanism can be arranged in a symmetrical position, improving the detection accuracy.

[0004] When using the above patent, we found that the device is not convenient for bending detection of cables, resulting in the inability to understand the deformation ability and recovery ability of cables when subjected to bending stress, thus affecting the detection effect of cables. Therefore, we propose a cable deformation detection device. Content of the Utility Model
