Copper wire traction machine with speed regulation function

The invention discloses a copper wire traction machine with a speed regulation function, which comprises a base, two symmetrical mounting plates are mounted on the base, a positive and negative screw rod is rotatably mounted between the two mounting plates, a crank handle is mounted at one end of the positive and negative screw rod, and a first traction mechanism and a second traction mechanism are respectively in threaded connection with the positive and negative screw rod. Positioning auxiliary mechanisms are arranged on the two sides of the first traction mechanism and the two sides of the second traction mechanism correspondingly, and the first traction mechanism comprises a first moving seat. The traction machine can perform tension traction on copper wires with different specifications, and the rotation speed is adjusted through the speed adjusting mechanism arranged in the first traction mechanism by utilizing the eccentric distance adjusting principle, so that the traction speed of the first traction
