In order to ensure the cleanliness of the distribution device, the cables need to be sorted. Generally, cable ties are used to bundle the cables together to prevent the cables from getting entangled with each other. However, when the cables need to be replaced after bundling, the cable ties are cut off and all the cables are scattered. After maintenance and replacement, the sorting work needs to be done again, which is time-consuming and laborious. Therefore, a device is urgently needed to solve the above problem.
