s6, grabbing annular A-phase lead wires, B-phase lead wires and C-phase lead wires, holding the annular A-phase lead wires, B-phase lead wires and C-phase lead wires into a bundle and cutting the bundle by using scissors;
s7, taking the unfinished parts of the broken A-phase lead wire, the B-phase lead wire and the C-phase lead wire as common lines, and sleeving the common lines into a common port (4) along the edge of the cover plate;
s8, according to the steps from S3 to S6, cutting off the three-phase lines of the rest groups, collecting the three-phase lines in a classified mode, subtracting the line heads in all collecting ports by using scissors, and ensuring that the length of the line heads is 8-15 cm;
s9, twisting all phase lines A in the phase A port into a twist shape and dividing the twist shape into two bundles;
s10, twisting all phase lines B in the phase B port into a twist shape and dividing the twist shape into two bundles;
s11, twisting all the phase lines in the phase C port into a twist shape, and dividing the twist shape into two bundles;
s12, twisting all the common lines in the common port into a twist shape, and bending and sleeving the common lines in the binding part.
