[0003] For example, Chinese patent publication number CN210334126U describes a simple steel bar bender structure, including a worm gear reducer, which includes a worm gear assembly and a motor. The bottom surface of the worm gear assembly is provided with a bottom plate, and the top surface of the worm gear assembly is fixed with a top plate. A vertical plate is fixed to one side of the top plate and the bottom plate. The motor is fixedly connected to the vertical plate, and the shaft end of the motor is coaxially fixedly connected to the worm shaft in the worm gear assembly. The upper end of the worm shaft on the worm gear assembly is provided with a flange.

[0004] However, in the above solution, when bending the steel bars, only one steel bar can be bent, which is inconvenient to bend multiple steel bars at the same time, resulting in low bending efficiency and low convenience of the steel bars. Summary of the Invention

[0008] As a further improvement of the present technical solution: the rotating device includes a second screw, which is fixedly connected to the side wall of the fixed block, and a rotating rod is threadedly connected to the side wall of the second screw. A second thread groove is provided on the side wall of the rotating rod, and one end of the second screw is threadedly connected to the second thread groove.

[0009] As a further improvement of the technical solution: a rubber pad is provided on the side wall of the outer ring of the rotating rod.

[0010] As a further improvement of this technical solution: the first screw and the second screw are both made of stainless steel.

[0011] As a further improvement of the present technical solution: the three clamping plates are all arranged in an arc shape, and the three clamping plates are adapted to the three clamping grooves arranged in an arc shape.

[0012] As a further improvement of this technical solution: the surface of the rotating block is provided with anti-slip grooves.

[0013] Compared with the existing technology, the beneficial effect of the present invention is that the device can bend multiple steel bars at the same time through the mutual cooperation of the fixed block, the baffle, the clamping plate, the sliding plate and other components, thereby improving the bending efficiency of the steel bars, and the operation is simple, convenient and fast.
