[0043] like Figure 1 , Figure 2 and Figure 3As shown, as a preferred embodiment, on the basis of the above method, further, the extrusion assembly includes a screw 604 threadedly connected to the inside of the bottom plate 603 and penetrating the top plate 601 and the partition 602, a pressure plate 606 fixed to the outside of the screw 604, and a rubber pad 605 fixed to both ends of the partition 602. A sliding structure is formed between the top plate 601 and the screw 604. The top plate 601 and the partition 602 are located on the same vertical center line. The bottom plate 603 and the mounting plate 10 are welded and integrated. The rubber pads 605 are evenly spaced inside the bottom plate 603. The wires are placed in the grooves between the bottom plate 603 and the partition plate 602 or between the partition plate 602 and the top plate 601, and the screw rod 604 is rotated to move downward through the engagement of the threads. At the same time, the screw rod 604 squeezes the top plate 601 through the pressure plate 606 to close the gaps among the top plate 601, the partition plate 602 and the bottom plate 603, thereby fixing the position of the cables and increasing the friction force of the cable fixation through the rubber pads 605.

[0044] like Figure 1 , Figure 2 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the loading and unloading structure 7 includes a movable shell 703 fixed on both sides of the interior of the box body 1, a roller 704 arranged inside the movable shell 703, a connecting frame 701 installed on one side of the roller 704 and connected to the mounting plate 10, a rotating seat 706 fixed on one side of the connecting frame 701, a cam 702 rotatably connected to the interior of the rotating seat 706, and a friction pad 705 fixed on one side of the cam 702, and a rotating member 704 is formed between the roller 704 and the connecting frame 701.
