Due to the action of the reset spring 132, the wiping belt 134 is in close contact with the cable to remove the impurities and water, so as to prevent the impurities and water from affecting the clamping of the cable, thereby improving the clamping effect of the cable. The cable with impurities and water removed continues to move downward and is placed on the support plate 2. The cable is between the left and right clamping plates 5, and then the cable is pushed The cable moves forward, so that the head end of the cable moves to the inner side of the annular plate 7 and contacts the airbag 8, the cable is stopped from being pulled forward, and then the driving motor 122 is started to drive the worm 123 to rotate, the worm 123 drives the worm wheel 121 to rotate, the worm wheel 121 drives the disc 12 to rotate, the disc 12 drives the contact rod 125 to rotate, the contact rod 125 drives the left and right side one-way hole plates 124 to move in a direction close to each other, the one-way hole plates 124 drive the left and right side movable plates 4 to move in a direction close to each other, the movable plates 4 drive the left and right side clamping plates 5 to move toward each other The movable plate 4 drives the piston plates 11 on the left and right sides to move in the direction of approaching each other, and the piston plates 11 move to push the air in the two-way cylinder 9 into the air guide tube 10, and the air in the air guide tube 10 is discharged into the air bag 8.

[0039] When the cable is placed on the support plate 2, the cable contacts the left and right conveying components 152, and the servo motor 153 can be started. The servo motor 153 rotates and drives the left rear rotating rod 151 to rotate through the bevel gear transmission.
