The cables 3 are output wiring harnesses, and a through hole is provided at the position of each of the fixed shells 1 corresponding to each of the cables 3 for the cables 3 to pass through.

[0024] When in use, the mobile frame 4 can be moved downward first, and then the length of the tensioning belt 2 and the tightness of the cable 3 between the two fixed shells 1 can be adjusted. After loosening the mobile frame 4, each reel 6 is rotated and limited under the action of the clamping plate 7, and the length of the tensioning belt 2 is fixed. Each cable 3 is fixed to the fixed shell 1 by friction under the action of the cable tie frame 5, and the length of the cable 3 between the two fixed shells 1 is also fixed. When any fixed shell 1 is subjected to tension, the tension will be transmitted to the other fixed shell 1 through each line, thereby protecting the cable 3 between the two fixed shells 1.
