[0055] In this embodiment, the second movable seat 640 is movably connected to the first movable seat 610, and the moving direction of the second movable seat 640 is perpendicular to the moving direction of the first movable seat 610. Through the second movable seat 640, the movable seat 420 can adapt to the horizontal changes of the workpiece during the correction process.

[0056] It is also worth explaining here that the two ends of the second return spring 650 are in contact with the first movable seat 610 and the second movable seat 640 respectively, so the second return spring 650 can play a role of flexible support for the second movable seat 640, and at the same time can push the second movable seat 640 to reset after the workpiece correction is completed and released, so that the correction of the next workpiece can be carried out.

[0058] In this embodiment, the lifting seat 660 can be lifted and connected to the second movable seat 640, and the lifting direction of the lifting seat 660 is perpendicular to the moving direction of the first movable seat 610 and the moving direction of the second movable seat 640. Through the lifting seat 660, the movable seat 420 can adapt to the changes in the vertical direction of the workpiece during the correction process.

[0059] It is also worth explaining here that the two ends of the third return spring 670 are in contact with the second movable seat 640 and the lifting seat 660 respectively, so the third return spring 670 can play a role of flexible support for the lifting seat 660, and at the same time can push the lifting seat 660 to reset after the workpiece correction is completed and released, so that the correction of the next workpiece can be carried out.

[0060] like Figure 1-Figure 11 As shown, on the basis of the above embodiment, the first rotating component 200 also includes a fourth return spring 240, and the fourth return spring 240 is arranged between the first base 210 and the first support block 230, and the two ends of the fourth return spring 240 are respectively in contact with the first base 210 and the first support block 230; the second rotating component 400 also includes a fifth return spring 450, and the fifth return spring 450 is arranged between the movable seat 420 and the second support block 440, and the two ends of the fifth return spring 450 are respectively in contact with the movable seat 420 and the second support block 440.

[0062] like Figure 1-Figure 11As shown, on the basis of the above embodiment, the first rotating component 200 also includes a first guide pin 250, the first support block 230 is provided with a first guide hole 231, one end of the first guide pin 250 is connected to the first base 210, the other end of the first guide pin 250 is movably connected to the first guide hole 231, and the fourth reset spring 240 is sleeved on the first guide pin 250; the second rotating component 400 also includes a second guide pin 460, the second support block 440 is provided with a second guide hole 441, one end of the second guide pin 460 is connected to the movable seat 420, the other end of the second guide pin 460 is movably connected to the second guide hole 441, and the fifth reset spring 450 is sleeved on the second guide pin 460.

[0063] In this embodiment, one end of the first guide pin 250 is connected to the first base 210, and the other end of the first guide pin 250 can move along the first guide hole 231. Therefore, when the first support block 230 rotates, the first guide pin 250 moves along the first guide hole 231 to guide the rotation of the first support block 230 relative to the first base 210, thereby preventing the first support block 230 from rotating and deviating. One end of the second guide pin 460 is connected to the movable seat 420, and the other end of the second guide pin 460 can move along the second guide hole 441. Therefore, when the second support block 440 rotates, the second guide pin 460 moves along the second guide hole 441 to guide the rotation of the second support block 440 relative to the movable seat 420, thereby preventing the second support block 440 from rotating and deviating.

[0064] It is also worth mentioning here that the fourth return spring 240 is sleeved on the first guide pin 250, so that the first guide pin 250 can not only play a guiding role, but also prevent the fourth return spring 240 from deflecting during the extension and retraction process.

[0065] It is also worth mentioning here that the fifth return spring 450 is sleeved on the second guide pin 460, so that the second guide pin 460 can not only play a guiding role, but also prevent the fifth return spring 450 from deflecting during the extension and retraction process.
