When the steel bar 4 contacts the first detecting component 22 of the first bending device, the arc bending device 1 stops working, the traction wheel 11 stops rotating, and the steel bar 4 is not conveyed any more. The second detecting member 23 may have the same structure as the first detecting member 22, and will not be described in detail here.
