The chain machine 20 is located below and in front of the feeding rack assembly 10, so that the PC steel bars 210 overturned and conveyed forwardly by the feeding rack assembly 10 fall by their own weight on the chain machine 20, and the PC steel bars 210 are received by the chain machine 20. The conveying groove 30 encloses a guide channel 31 for the threaded steel bar raw material unwound by the unwinding mechanism 40 to be conveyed forwardly in a straight line when in the closed position. The cutter 50 is used to cut the threaded steel bar raw material at a position between the conveying groove 30 and the unwinding mechanism 40. When in the open position, the conveying groove 30 makes the threaded steel bars 220 cut by the cutter 50 and left in the guide channel 31 fall on the chain machine 20, which is used to convey the PC steel bars 210 and the threaded steel bars 220 to the tendon machine outside to meet the feeding needs of the mixed automatic tendon of the tendon machine. It should be noted that the PC steel bars 210 can be fed to the feeding rack assembly 10 by hand or by a mechanical hand, but this is not limited. In addition, according to actual needs, the unwinding mechanism 40 can be located on the left side of the conveying groove 30, so the above description is not limited. More specifically, as follows:
