Then tighten the bolts 3 to fix the lower bridge frame 1 and the upper bridge frame 2. By setting the lower clamping plate and the elastic member 1 , the upper clamp and the elastic part 2 can support and fix the cables inside the bridge, so that the cables are arranged in order and prevent the cables from being squeezed together; when the cable heats up, start the semiconductor refrigeration sheet 19 to cool the gas inside the heat dissipation box, and then start the hair dryer 17 to blow cold air on the surface of the cable to dissipate heat.
