The driving gear 17 drives the rotating table 9 to rotate, so that the first bending column 14 and the second bending column 15 bend the steel bar.

[0025] Please see Figures 1-4 In this embodiment, the surfaces of the support base 5 and the fixed platform 2 are fixedly connected. The driving component 6 is a telescopic cylinder, which is fixedly connected to the front side of the support base 5. The output end of the driving component 6 extends to the rear side of the support base 5 and is fixedly connected to the clamping plate 4. The lower end of the clamping plate 4 is slidably connected to the surface of the fixed platform 2. The lower end of the adjusting screw 7 is rotatably connected to the fixed platform 2.

[0027] During operation, the first drive component 6 drives the clamping plate 4 to move closer to the limiting block 3, thereby clamping the reinforcing bar in the front-to-back direction. By rotating the knob, the adjusting screw 7 is rotated, causing the limiting plate 8 to slide along the outside of the limiting block 3 until it is tightly fitted with the reinforcing bar, thereby limiting and pressing the reinforcing bar in the up-down direction.
