[0009] Further, in the embodiment of the present invention, the wire-changing rod is connected inside the main body housing. The wire-changing rod is located at the rear end of the main body housing. Two sections of sliding grooves are provided on the surface of the wire-changing rod, a wire-changing column. The wire-changing column is connected to the wire-changing rod. The inside of the wire-changing column is hollow. A boss is provided at the lower end inside the wire-changing column, a wire-changing frame. The wire-changing frame is connected to the upper end of the wire-changing column. An installation ring is provided in the middle of the wire-changing frame. Two installation platforms are provided on each of the left and right sides inside the installation ring in the middle of the wire-changing frame, a wire-changing gear.

[0012] A method for using a quick connector of an LNG tanker, comprising the following steps:

[0013] After the wire is fixed on the guide wheel disc, the motors on both sides of the main body shell start, the guide wheel track begins to rotate, and the cable enters the wire changing device. When the wire is continuously fed on the guide wheel disc, the wire will move irregularly from side to side. When the wire moves to the left, the wire will hit the wire changing shaft on the left side of the wire changing device. After the left wire changing shaft is stressed, it will rotate clockwise. The lower end of the left wire changing shaft disengages from the chute of the wire changing rod, and the upper end of the left wire changing shaft meshes with the left wire changing gear. The left wire changing gear rotates counterclockwise to drive the right wire changing gear to rotate clockwise. The right wire changing gear meshes with the upper end of the right wire changing shaft, and the right wire changing shaft rotates counterclockwise. The lower end of the right wire changing shaft disengages from the chute of the wire changing rod, and both ends of the wire changing shaft disengage from the wire changing rod. The wire changing column loses its fixation and moves along the left direction of the cable. When the wire moves to the right, the wire will hit the wire changing shaft on the right side of the wire changing device. After the right wire changing shaft is stressed, it will rotate counterclockwise. The lower end of the right wire changing shaft disengages from the chute of the wire changing rod, and the upper end of the right wire changing shaft meshes with the right wire changing gear. The right wire changing gear rotates clockwise to drive the left wire changing gear to rotate counterclockwise. The left wire changing gear meshes with the upper end of the left wire changing shaft, and the left wire changing shaft rotates clockwise. The lower end of the left wire changing shaft disengages from the chute of the wire changing rod, and both ends of the wire changing shaft disengage from the wire changing rod. The wire changing column loses its fixation and moves along the right direction of the cable.

[0014] After the cable enters the wire guiding device from the wire changing device, the wire guiding deflection ball swings and adjusts in the left and right directions under the drive of the cable, and finally the cable enters the second wire guide wheel and the third wire guide wheel for deflection adjustment, and finally the cable is led out by the fourth wire guide wheel.

[0015] Beneficial effects: When the wire is fed out from left to right, after the wire changing device makes adaptive adjustments, the wire will enter the wire guiding device from different directions. When the chute on the surface of the wire guiding deflection ball of the wire guiding device receives the wire, pressure is applied to both sides according to the feeding direction of the wire. The wire guiding deflection ball slides on the ball head at the left end of the first wire guide wheel, changing the orientation of the connection, and avoiding wire jumping during wire guiding.
