[0002] In the process of sporadic steel bar construction, we often encounter situations where the stirrups are of inappropriate size or lack of stirrups, and we need to prepare materials on site according to the actual situation. In the prior art, a stirrup bending machine is used to bend the steel bars. Since the stirrups to be bent are generally cross-shaped with the main bars, the operating space is small, resulting in the bending of the stirrup bending machine being not flexible enough; the stirrup bending machine itself has a complex structure, large size and heavy weight. During the layout process, it requires the use of lifting machinery and more people to cooperate, and it also needs to be connected to a power supply, which is labor-intensive and cannot be used in locations without a power supply, and has high requirements for on-site construction; and since the amount of work is small, it is time-consuming, labor-intensive and uneconomical to set up a stirrup bending machine alone.
