The cable is transported during the movement of the vehicle body, and then multiple bottom plates 12 are inverted and loaded into the slide groove of the slide 26, so that the wire supporting part 13 and the screw rod 14 are located at Under the carriage 26, the lower end of the screw 14 faces the cable, and the elastic force of the spring 29 pushes the slide bar 28 and the push plate 27 toward the discharge port of the slide slot of the carriage 26, so that the push plate 27 stably conveys multiple bottom plates 12 to the discharge port. Then, when the elastic tube 7 of the cable reaches the discharge port below the slide slot of the carriage 26, the piston rod of the push cylinder 3 30 extends to push the bottom plate 12 out of the slide slot of the carriage 26, so that the screw 14 passes through the elastic tube 7, and the protrusion in the middle of the bottom plate 12 is stuck in the corresponding slot 5, and the wire supporting part 13 is pressed. On the outer wall of the cable, after multiple wire pressing parts 15 are loaded into the slide 31, the output shaft of the push cylinder 4 32 is extended to push the push plate 2 33 to move, so that the push plate 2 33 transports the multiple wire pressing parts 15 to the outlet of the slide 31, so that the wire pressing part 15 moves out of the outlet of the slide 31, and the middle part of the wire pressing part 15 is penetrated on the screw 14, and the middle part of the wire pressing part 15 is penetrated on the screw 14, and the protrusion in the middle part of the wire pressing part 15 is stuck in the corresponding card groove 5, and finally when the bottom plate 12 and the wire pressing part 15 move with the cable to the nut to tighten When the bottom plate 12 reaches below the two bolt tightening machines 20, the vehicle body pauses, and the nut tightening machine 19 screws the nut 16 to the screw rod 14, so that the nut 16 presses the wire pressing part 15, so that the wire pressing part 15 and the wire supporting part 13 cooperate to hold the cable tightly, and the vehicle body continues to move. When the bottom plate 12 reaches below the two bolt tightening machines 20, the vehicle body pauses, and the two bolt tightening machines 20 screw the bolts through the two mounting holes of the bottom plate 12 and fasten them to the mounting position of the high-pressure pipe or high-pressure tank, and the vehicle body continues to move, thereby realizing the automatic installation of the cable.
