[0084] In this embodiment, the stirrup conveying driver 12 is a motor, and the gearbox is a conventional component in the art, which will not be elaborated here.

[0085] In other embodiments, it may also be that each stirrup conveying rack 11 is provided with one screw conveyor 13, and each screw conveyor 13 is directly driven by one motor.

[0086] Specifically, the stirrup conveying device 1 further includes a stirrup size adjusting mechanism 14. The stirrup size adjusting mechanism 14 can adjust the distance between the two stirrup conveying racks 11.

[0094] In this embodiment, the feeding driver 212 is a stepping electric cylinder, and the stroke of driving the welding clamping module 22 to move each time is precisely fixed. When the stroke of one step of the welding clamping module 22 cannot reach the distance between two adjacent stirrups 100 in the steel cage to be processed, the feeding driver 212 can also drive the welding clamping module 22 clamping the stirrup 100 and the main reinforcement 200 to step multiple times until the distance between two adjacent stirrups 100 in the steel cage to be processed is reached.

[0095] In other embodiments, the feeding driver 212 can also be other devices such as a linear motor, which is not limited herein.
