On one side of the upper end surface of the processing table 101, symmetrically distributed first mounting plates 201 are installed. A first threaded rod 202 is rotatably installed between the first mounting plates 201, and a first movable block 204 is threadedly installed on the first threaded rod 202.

[0023] In this embodiment, the steel bar is arranged on the upper end of the processing table 101, and both ends of the steel bar are located between the positioning columns 104. The positions of the first bending mechanism 300 and the second bending mechanism 400 are adjusted according to the position where the steel bar needs to be bent. By operating the first driving device 203, the first threaded rod 202 can be rotated. With the cooperation of the first movable block 204, the position of the first bending mechanism 300 can be adjusted. By operating the second driving device 207, the second threaded rod 206 can be rotated. With the cooperation of the two second movable blocks 208, the positions of the two second bending mechanisms 400 can be adjusted. Then, the steel bar bending work can be carried out by the first bending mechanism 300 and the two second bending mechanisms 400.

[0026] Further, a right-handed thread structure and a left-handed thread structure are provided on the second threaded rod 206, and the right-handed thread structure and the left-handed thread structure are symmetrically distributed with respect to the second threaded rod 206. A second driving device 207 is installed at the side end of the second mounting plate 205, and the spindle of the second driving device 207 is connected to the axis of the second threaded rod 206.
