Therefore, through this application, multiple prefabricated components can be stably limited in multiple directions while the loading of the prefabricated components is completed, avoiding the deviation of multiple prefabricated components during bending, thereby effectively improving the processing quality of the prefabricated components.

The bottom surface of the bending block 31 and the top surface of the bending support workbench 4 can be driven by the rotating portion to be parallel to each other. In the parallel state, an upper and lower gap is formed between the bending block 31 and the bending support workbench 4 to accommodate the prefabricated component. Therefore, after the driving motor 2 is operated, the bending block 31 connected to the movable disc 3 can be driven to rotate through the cooperation of the first rotating shaft column 22, the second rotating shaft column 23 and the tooth chain 24 to process the end of the prefabricated component.
