Therefore, by pushing and pulling the connecting base 505 with the cylinder 507, and by pulling the rod 506, the parallel rod assembly 503 moves the grippers 504 closer or further apart, thus clamping the hardware. The second servo motor 509 drives the second gear 510 to rotate the gear ring 511, causing the grippers 504 to hold the hardware and rotate for easier processing.
