Further, since two limiting components 2 are relatively arranged in several drag chain links 1, and support frame 3 in limiting component 2 is installed on drag chain link 1 by elastic member 9, elastic member 9 can be spring in prior art, spring has the characteristics of compact structure, large elastic deformation force, so that support frame 3 can be moved relative to drag chain link 1 under the action of elastic member 9;At the same time, since roller 4 is detachably rotatably installed on support frame 3, the mounting mode of roller 4 and support frame 3 can be pin articulation, so that roller 4 can rotate relative to support frame 3, and the structure is simple and reasonable. Understandably, when staff puts cable into drag chain link 1, cable is between two rollers 4 at this time, and support frame 3 makes roller 4 abut with the outer wall of cable under the rebound action of elastic member 9, so that cable can be clamped and limited by two rollers 4, which can effectively prevent cable from being worn by long-term sliding friction with drag chain link 1, not only effectively slow down the aging speed of cable, prolong the service life of cable, but also reduce the frequency of maintenance and replacement of cable, save maintenance cost. In addition, when multiple cables need to be installed, since support frame 3 is formed with several limiting posts 5 along its extension direction, and two adjacent limiting posts 5 can enclose limit hole 6 for cable to pass through with two rollers 4, so that the movement of cable between two rollers 4 along the width direction of drag chain link 1 can be prevented by limiting post 5, which not only effectively avoids the confusion and entanglement of multiple cables, but also improves the installation stability and management efficiency of multiple cables, which is beneficial to maintenance.

[0034] It should be noted that when the utility model is bent or stretched, cable is bent synchronously with several drag chain links 1 at this time, and in this process, the friction between roller 4 and cable is rolling friction, which can reduce the friction between cable and roller 4, effectively reduce the risk of cable wear.
