[0003] At present, there are still the following problems in steel bar positioning:

[0004] 1. When connecting the positioning stirrups with the four main bars, it is generally necessary to pull the joints of the positioning stirrups to create gaps at the joints of the positioning stirrups. Then, the four main bars are passed through the gaps of the positioning stirrups in sequence, which makes it more difficult to connect the positioning stirrups with the four main bars.
