[0036] Specifically, when the reinforcing steel bars need to be fixed, the user can move the connecting ring 18 through the output end of the air cylinder 17 after the reinforcing steel bars pass through the fixing frame 19. When the connecting ring 18 is subjected to force, it will push the internal connecting rod 22 to move. The movement of the connecting rod 22 will drive the connecting block 21 to move along the track of the fixing frame 19, thereby driving the rotating ring 20 to rotate. Under the action of force, the rotating ring 20 will drive the multiple supporting blocks 24 at one end to move.
