[0034] In the present invention, the chuck 101 is numerically controlled to clamp the shaft 102 and drive the shaft 102 to rotate, and the fixing member 103 clamps the ends of the multiple strands of steel wires and winds the steel wires during the rotation of the shaft 102 to form a spring.

[0035] Furthermore, the moving block 200 is controlled to move by the screw rod 104, the steel wire passes through the guide hole 201e, and is straightened by the distance adjusting member 202, and the position of the distance adjusting member 202 is lower than the positions of the shaft rod 102 and the steering member 201, achieving a downward pressure effect, so that the steel wire has a larger contact area on the shaft rod 102, which is convenient for shaping.

[0036] The steering member 201 is used to adapt the winding pitch of the spring guide wire.

[0037] The fixing member 103 includes a ring plate 103a, which is disposed on the shaft 102; the ring plate 103a is provided with a first threaded hole 103b, and a first bolt 103c is disposed in the first threaded hole 103b.

[0043] It should be noted that a pull ring is provided on the top of the steering member 201. When the steering member 201 is pulled upward, the ring tooth 201c leaves the tooth groove 200e, and the angle of the steering member 201 is adjusted. Then, the steering member 201 is lowered so that the ring tooth 201c is embedded in the tooth groove 200e and fixed under the action of the spring 201d.

[0044] A fan groove 200f is arranged on the side of the moving block 200, a round shaft 200g is arranged in the fan groove 200f, a support rod 202a is arranged below the distance adjusting member 202, a through hole 202b is arranged on the support rod 202a, the round shaft 200g is arranged in the through hole 202b, and the support rod 202a is arranged in the fan groove 200f.

[0045] The fan groove 200f limits the rotatable angle of the support rod 202a.

[0046] The distance adjusting member 202 is provided with a through slot 202c, and the through slot 202c is provided with transverse slots 202d at the upper and lower ends. The moving rod shaft 203 is provided with end blocks 203a at both ends.

[0049] The distance adjusting member 202 rotates together with the steering member 201. Specifically, the distance adjusting member 202 and the steering member 201 are connected by a telescopic rod, and both ends of the telescopic rod are axially connected to the distance adjusting member 202 and the steering member 201, so that when the steering member 201 is lifted, it does not affect the distance adjusting member 202, but the distance adjusting member 202 rotates together with the steering member 201.

[0050] Specifically, the steel wire passes through the groove 202c, and the multiple strands of steel wire are placed on one side of the sleeve 203b.
