[0035] In this embodiment, the metal material is first placed at the center of the first gripper 23 and the second gripper 24. Then, the first motor 31 is turned on to drive the bidirectional threaded rod 32 to rotate. After that, the bidirectional threaded rod 32 will drive the moving frame 33 to slide on the side wall of the stabilizing rod 36 through the stabilizing plate 35, so that the moving frame 33 can drive the clamping plate 34 to position the metal material.
