A plurality of evenly distributed cylinders 42 are fixedly installed on the top of the support plate 41, and the output ends of the cylinders 42 are respectively connected to the movable rods 44 on the same side. By controlling the cylinders 42, at this time, the piston rods in the cylinders 42 can drive the movable rods 44 to move, and then the support plate 43 cooperates with the connecting rods 45 to drive the movable plate 47 to move in the slide groove 48, so that the position of the arc-shaped limit plate 46 can be adjusted accordingly, so that it can be suitable for copper wires of different specifications and sizes to limit and fix. Moreover, by having multiple copper wire limiting mechanisms 4 work at the same time, the efficiency of copper wire tinning can be increased and the workload of the staff can be reduced.
