[0021] The present utility model will be further described in detail below with reference to the drawings.

[0022] Please refer to Figures 1 - 2 , a steel wire heat treatment device, including a quenching box body 1, and a plurality of guide wheels 2 are arranged inside the quenching box body 1. A steel wire 3 is wound between the guide wheels 2;

[0023] Inside the quenching box body 1, several heating rods 4 are provided, and a first stirring module is provided on the left side of the quenching box body 1, and a second stirring module is provided on its right side;

[0024] The first stirring module includes a first stirring motor 5. The first stirring motor 5 is horizontally fixed on the left side surface of the quenching box body 1. A first stirring rod 7 is fixed on the rotor of the first stirring motor 5. The right end of the first stirring rod 7 is rotationally limited on the first support plate 9. Several first stirring fan blades 11 are provided on the first stirring rod 7;
