[0045] The working principle of the above embodiment is as follows: the spring that needs heat treatment is placed on the top of the conveying mechanism 17, the conveying mechanism 17 starts working and drives the spring to move into the inside of the heat treatment mechanism 1, the motor 12 works, drives the corresponding second transmission rod 9 to rotate clockwise, so that the corresponding sleeve 8 drives the corresponding first gear 7 to rotate clockwise, and the first gear 7 drives the corresponding paddle 5 to swing counterclockwise through the teeth 6. At the same time, the paddle 5 drives the first transmission rod 4 to rotate, so that the paddle 5 paves the spring at the top of the conveying mechanism 17. When the second transmission rod 9 connected to the motor 12 rotates clockwise, it will drive the rotating rod 14 to rotate clockwise through the belt 13, so that the third gear 15 rotates clockwise, and the third gear 15 drives the second gear 16 to rotate counterclockwise.
