[0035] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.
[0036] In actual application, the No. 2 motor 1202 drives the traction roller 1203 to rotate, and the optical fiber cable is placed between the two sets of traction mechanisms 12. The optical fiber cable will continue to rise until it passes through the limit opening on the bending mechanism 5, and then the No. 1 cylinder 503 pushes the fixed block 504 to fix the optical fiber cable. The setting of the anti-slip pad increases the friction force when the fixed block 504 contacts the optical fiber cable, so that the optical fiber cable can be better fixed. The No. 2 cylinder 11 pushes the two sets of traction mechanisms 12 closer to each other, thereby clamping and fixing the lower position of the optical fiber cable, and then the No. 1 motor 6 drives the swing arm 502 to rotate to perform a bending test on the optical fiber cable. After the test is completed After reaching a position, the optical fiber cable will continue to rise with the traction and transportation of the traction mechanism 12, and the bending mechanism 5 will test different positions of the optical fiber cable. The traction mechanism 12 controls the extension and contraction distance of the guide block 9 through the No. 2 cylinder 11, so it is convenient to pull and transport optical fiber cables of different diameters. After the test, the connecting plate 4 is turned over and laid flat through the damping shaft 3, and the bending mechanism 5 and the traction mechanism 12 on the connecting plate 4 will be stored in the storage groove 10.

[0037] In summary, with the aid of the above-mentioned technical scheme of the utility model, the optical fiber cable can be pulled and transported by setting up two sets of traction mechanisms 12. After completing the bending test at one point, the cable is pulled and transported so that different positions of the optical fiber cable pass through the bending mechanism 5. Moreover, the traction mechanism 12 controls the extension and contraction adjustment distance of the guide block 9 through the No. 2 cylinder 11, so it is convenient to pull and transport optical fiber cables of different diameters. When the bending mechanism 5 is in use, the No. 2 cylinder 11 can also push the two sets of traction mechanisms 12 closer to each other, so as to clamp and fix the lower position of the optical fiber cable to prevent the lower end of the optical fiber cable from swinging during the test. The setting of the damping shaft 3 allows the connecting plate 4 to be flipped and laid flat, and the bending mechanism 5 and the traction mechanism 12 on the connecting plate 4 are stored in the storage groove 10. The flexible rubber pad and sponge pad in the storage groove 10 can play a buffering and protective role on the bending mechanism 5 and the traction mechanism 12 on the connecting plate 4 when the test bench 1 shakes during movement.
