The rear side of the U-shaped block 3 is rotatably connected to the screw 2.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

Furthermore, any aspects not detailed in this utility model are well-known technologies to those skilled in the art.

[0028] The working principle of the above embodiments is as follows:

[0029] The rear pressure mold 4 is mounted on the rear end plate 12 via the rear mounting seat 1. A cylindrical pin 5 and a U-shaped block 3 are installed on the rear pressure mold 4. By rotating the screw 2, the U-shaped block 3 is pushed forward in the guide groove of the rear pressure mold 4, forming a closed U-shaped cavity with the cylindrical pin 5. The middle part of the elastic wire pre-installed in the positioning groove 401 of the rear pressure mold 4 is bent and formed into a U-shaped structure. The middle pressure mold 6 is mounted on the slide 13. The left and right wires formed into U-shaped structures are crossed and inserted into the positioning groove 401 of the middle pressure mold 6 and attached to the outside of the cylindrical pin 5. By driving the manual slide module, the middle pressure mold 6 moves backward, causing the rear pressure mold 4 and the middle pressure mold 6 to compress the middle part of the elastic wire into the required 140° single-turn torsion spring structure. The front pressure mold 8 is mounted on the front end plate 12 of the manual slide module via the front mounting seat 9. The machine is equipped with four positioning baffles 7. One end of the wire to be formed is placed horizontally behind the front pressure mold body 8 and positioned between the upper and lower positioning baffles 7. The slide 13 of the manual slide module is driven to move the middle pressure mold body 6 forward and gradually close with the front pressure mold body 8, extruding the wire end into the required "Z" shape. The other end is then placed in the same direction and the operation is repeated to complete the wire forming process of the other end. The commonly used manual slide module is used as the power drive device, and a simple elastic wire forming device is added to achieve bidirectional forming processing. This completes the forming of the flexible single-turn torsion spring structure in the middle of the elastic wire and the bending forming of the claws at both ends of the elastic wire. This not only has the advantages of reducing costs and improving production efficiency, but also solves the problem of high production costs and low production efficiency caused by using multiple conventional torsion spring forming devices for batch production.
