[0014] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Example: Figure 1-Figure 4 As shown, a wire straightener comprises a handle 1 and a handle 2, one end of the handle 1 and the other end of the handle 2 are hinged by a hinge shaft 3 and can keep in close contact after rotation, one side of the handle 1 is equipped with four fixed pulleys 4 arranged evenly at intervals, and the handle 2 2 is equipped with a staggered fixed pulley 2 5 and two floating fixed pulleys 6 on the same side of the fixed pulley 1 4, one fixed pulley 2 5 and two floating fixed pulleys 6 are located between two adjacent fixed pulleys 4, and a threading hole is formed between the four fixed pulleys 4 and the one fixed pulley 2 5 and the two floating fixed pulleys 6. When in use, the wires are placed on the four fixed pulleys 4, and the handle 2 is rotated to cover the wires. Under the action of traction, the wires pass through the threading hole, thereby straightening the wires.

[0016] Preferably, the four fixed pulleys 4 are rotatably connected to the U-shaped wheel frame 7 through screws 15, and the inner end of the screw 15 contacts the fixed pulley 1 and is a bare rod structure, which is convenient for the rotation of the fixed pulley 1.
