[0027] Specifically, first driving mechanism 41 includes two drive cylinders that drive first clamp 21 and second clamp 22 respectively, with the table top of positioning table 1 as reference surface, the first clamp 21 and the second clamp 22 are arranged on the transverse two sides of the volute spring 3, and the adjustment assembly is located above the volute spring 3 in vertical direction.

[0028] Further, the second driving mechanism 42 is a cylinder, the first slider 51 is connected to the vertical upper position of the positioning table 1 by the cylinder, and the second slider 52 is connected to the first slider 51. After the volute spring 3 is fed onto the table top of the positioning table 1, the first slider 51, the second slider 52 and the positioning pin 521 are driven by the cylinder to transversely displace relative to the volute spring 3. During the displacement process, the positioning pin 521 moves to cooperate with the volute spring hook 31 and drives the volute spring 3 to rotate as a whole until it rotates to the desired position. Since the second slider 52 can slide relative to the first slider 51, the outer cylindrical surface of the volute spring 3 is a curved surface, and the positioning pin 521 interacts with the volute spring hook 31 during transverse displacement, so that the motion trajectories of the positioning pin 521 and the volute spring hook 31 are curves. Therefore, during the transverse displacement of the first slider 51 and the rotation of the volute spring 3 driven by the positioning pin 521, the second slider 52 is vertically displaced relative to the first slider 51 driven by the positioning pin 521.

[0032] In an embodiment, the first sliding block 51 is provided with a sliding groove, and the second sliding block 52 is slidingly limited in the sliding groove and can vertically displace relative to the first sliding block 51; in the process of driving the first sliding block 51 by the second driving mechanism 42 to drive the second sliding block 52 to displace transversely relative to the coil spring 3, the positioning pin 521 drives the coil spring hook portion 31 to move, and since the coil spring 3 is limited and cannot move but only rotate, the coil spring hook portion 31 interacts with the positioning pin 521, so that the positioning pin 521 and the second sliding block 52 vertically displace relative to the first sliding block 51, and the movement trajectory of the positioning pin 521 is an arc line.

[0033] In an embodiment, an elastic member 6 is arranged between the first slider 51 and the second slider 52, and the elastic member 6 is stretched or compressed to drive the second slider 52 to return during vertical sliding of the second slider 52 relative to the first slider 51; the elastic member 6 is a tension spring, and the tension spring has elastic potential energy to keep the positioning pin 521 abutting against the coil spring 3 during movement of the second slider 52; a person skilled in the art can also set the elastic member to other elastic parts or assemblies having a return function according to requirements, for example, a metal spring leaf.

[0034] Specifically, the first slider 51 is provided with a first positioning column 511, the second slider 52 is provided with a second positioning column 522, one end of the tension spring is connected to the first positioning column 511 of the first slider 51, and the other end of the tension spring is connected to the second positioning column 522 of the second slider 52, and the second positioning column 522 is always located above the first positioning column 511 during movement of the second slider 52.
