The support frame 510 is arranged on the machine base 100, and the first clamp 520 and the second clamp 530 are arranged at both ends of the connecting rod 540. The fourth driving assembly 550 is driven and connected to the connecting rod 540 and drives the connecting rod 540 to rotate, so that one of the first clamp 520 and the second clamp 530 clamps the stator from the transportation mechanism 400 and rotates toward the supporting mechanism 200, and the other of the first clamp 520 and the second clamp 530 clamps the stator from the supporting mechanism 200 and rotates toward the transportation mechanism 400.
