Description

Technical Field

[0001] This utility model relates to the field of cable bending resistance testing, and in particular to a bending resistance testing device for ultra-flexible, high-strength cables. Background Technology

[0002] Traditional methods for testing cable bending resistance typically require manual methods to fix and bend the cable.

This method has several drawbacks: First, it requires a large amount of manual operation, resulting in low efficiency and high labor intensity; second, due to the uncontrollability of manual operation, uneven stress on the cable during bending can easily occur, thus affecting the accuracy of the test.
