[0032] Thirdly, if the distance between the copper wires needs to be adjusted during the twisting process, the operator loosens the bolts in the clamping block 29, turns the adjusting disc 16, and when the adjusting disc 16 rotates, the position of the second sliding groove 19 changes, causing the sliding track of the second wire block 11 in the first sliding groove 12 to change, thereby changing the relative position between the second wire block 11 and the first wire block 18, achieving the adjustment of the distance between the copper wires.
