[0017] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3 , the concave rotating plate 5 is provided with a placement groove 6, the limiting structure includes a fixed cylinder 10 fixedly connected to one side of the vertical plate 2, the fixed cylinder 10 is provided with a cavity 11, the cavity 11 is provided with an electric telescopic rod 12, the vertical plate 2 is provided with a through groove 14 cooperating with the electric telescopic rod 12, one end of the electric telescopic rod 12 is provided with a limiting clamp 13 between the concave rotating plates 5 on both sides, the concave rotating plate 5 is provided with a rotating shaft connected to the vertical plate 2 at one end close to the limiting clamp 13, the surface of the limiting clamp 13 and the inner wall of the placement groove 6 are adhered with anti-slip soft pads, which can avoid collision between the steel pipe, the steel bar and the surface of the limiting clamp 13 and the inner wall of the placement groove 6, resulting in wear of the steel pipe and the steel bar, and the vertical plate 2 is provided with a marking line 15, which is convenient for aligning the steel pipe and the steel bar when placing them.

[0018] When the utility model is implemented in practice, when in use, when it is necessary to bend the steel bars, specifically, the steel bars are placed in the placement grooves on both sides. At this time, the concave rotating plates on both sides are in a horizontal state. Then, the electric telescopic rod is controlled to contract, which can drive the limit clamping block to move in the direction of the vertical plate until the limit clamping block is close to the surface of the steel bar and the limit clamping block is located above the steel bar. Then, the bending can begin. Specifically, the oil cylinders on both sides are opened and the oil cylinders are controlled to extend. Since the oil cylinders are rotatably connected to the bottom of the concave rotating plate and the rotating block is rotatably connected to the vertical plate, the extension of the oil cylinders can drive the concave rotating plate to rotate, and at the same time, the sliding rod will move in the stroke groove, and the rotation of the concave rotating plates on both sides can drive the steel bars to bend, and the steel bars located under the limit clamping blocks will be limited by the limit clamping blocks. After the bending is completed, the electric telescopic rod is controlled to extend and the concave rotating plate is controlled to rotate in the opposite direction, so that the bent steel bars can be taken out. The utility model is easy to operate during use and has a simple structure.
