[0004] In order to solve the problem of fixing the cable tube, the existing technology is to set up a limit frame, and then use long partitions and short partitions to quickly adjust the lateral and longitudinal spacings of the cable tubes, and fix the tubes in a way of tightening with the first threaded rod and the second threaded rod. However, this fixing method is connected by bolts, which requires workers to use tools to tighten the fixings one by one, which brings inconvenience to the installation and reduces the efficiency of the cable tube.

[0030] Example 3

[0031] like Figure 1-5As shown, on the basis of Examples 1-2, the utility model provides a technical solution: preferably, the fixing unit includes a positioning block 34 fixedly installed on the top of the clamping block 32, a cavity 24 is opened on the top right side of the fixing device 2, and movable grooves 25 are opened on both sides of the interior of the cavity 24, and sliding cross bars 26 are fixedly installed at both ends of the interior of the movable groove 25, and a sliding block 27 is slidably sleeved on the outer surface of the sliding cross bar 26, and a return spring 28 is movably sleeved on the outer surface of the sliding cross bar 26, one end of the return spring 28 is fixedly installed on the left side of the sliding block 27, and the other end of the return spring 28 is fixedly installed on the inner end of the movable groove 25, and a moving plate 29 is fixedly installed on the inner side of the sliding block 27, and bearing rods 210 are fixedly installed on both sides of the other end of the moving plate 29, and a positioning frame 211 is rotatably sleeved on the outer surface of the bearing rod 210, and the positioning frame 211 is movably sleeved on the outer surface of the positioning block 34.
