[0035] The working principle and use process of this utility model:

[0036] First, the steel wire is passed through the straightening structure and positioning mechanism 300 and extended into the machine body 100, and the bidirectional screw 303 is rotated by the hand crank 311, and the bidirectional screw 303 drives the two screw sleeves 307 to move closer to each other, and the screw sleeves 307 drive the cross plate 308 to move the upper base 301 and the lower base 302 relatively until the active roller 305 and the auxiliary roller 304 contact the surface of the steel wire, and the motor 306 drives the active roller 305 to rotate and cooperate with the auxiliary roller 304 to send the steel wire into the machine body 100 for processing through friction. Since the positions of the active roller 305 and the auxiliary roller 304 are adjustable, they can adapt to the clamping and feeding of steel wires of different thicknesses for processing, and the scope of application is effectively improved;

[0037] When the bidirectional screw 303 rotates, the driving sprocket 310 can be driven to rotate. The driving sprocket 310 drives the driven sprocket 406 to rotate synchronously through the chain 500 and drives the first worm 402 to rotate. The first worm 402 rotates the second worm 403 through the meshing of the first bevel gear 407 and the second bevel gear 408. The second worm 403 rotates through the meshing of the third bevel gear 409 and the fourth bevel gear 410 to rotate the third worm 404. The third worm 404 rotates through the meshing of the fifth bevel gear 411 and the sixth bevel gear 412 to rotate the fourth worm 405. Therefore, when the bidirectional shaft rotates, the first worm 402 can rotate, and the second worm 403, the third worm 404 and the fourth worm 405 can follow and rotate synchronously.

[0038] The first worm 402 rotates, and the second worm 403, the third worm 404 and the fourth worm 405 rotate synchronously to drive the corresponding worm wheel 414 to rotate. The sleeve 413 rotates following the worm wheel 414 and drives the stud 415 to move the long strip 416 through thread transmission. Multiple long strips 416 move synchronously toward the center of the cross-shaped bracket 401 to clamp the steel wire. The setting of the ball 417 allows the steel wire to move forward without being clamped, and cooperates with the adjustment of the active roller 305 and the auxiliary roller 304 to achieve multi-point positioning. As the steel wire is sent into the machine body 100 for processing, the steel wire clamped by multiple groups of balls 417, the active roller 305 and the auxiliary roller 304 will be straightened to facilitate processing.

[0039] In summary, the positions of the active roller 305 and the auxiliary roller 304 for clamping the steel wire in the utility model are adjustable, so it can adapt to the clamping and feeding of steel wires of different thicknesses for processing, and the scope of application is effectively improved; the straightening mechanism 400 is linked with the positioning mechanism 300 to clamp the steel wire without affecting the advancement of the steel wire, thereby playing a further positioning role, and cooperating with the active roller 305 and the auxiliary roller 304 to straighten the steel wire, which is convenient for subsequent processing.
