The support roller 3 is driven to rotate by the servo motor 4, so that the steel bars can be transported.

[0024] like Figure 1-4 As shown, grooves are provided on the arc surfaces of the support roller 3 and the limit roller 8, and the upper end of the support frame 2 is located at the front and rear sides of the support roller 3 and is fixedly connected with a first support platform 5 and a second support platform 6 respectively.
