[0026] There are eight pulleys 15 rotatably connected to the bottom of the movable block 3. The eight pulleys 15 are equidistantly distributed in a linear array on the bottom surface of the movable block 3. Each pulley 15 corresponds to eight lower rotating tubes 8.

[0029] A second electric push rod 22 is installed on the top of the second fixing frame 7. The telescopic end of the second electric push rod 22 extends to the bottom surface of the second fixing frame 7 and is fixedly connected to a lower pressing block 23.

At this time, the lower pressing block 23 is pushed down by the telescopic end of the second electric push rod 22. Because the inclined surface of the opening of the lower pressing block 23 is adapted to the inclined surfaces of the two clamping blocks 20, the two clamping blocks 20 move relative to each other. The serrated grooves on the opposite surfaces of the two clamping blocks 20 can firmly clamp the steel wire to prevent displacement and rotation. By installing a bending rod 24 of the required size on the bending mold turntable 18, the bending mold turntable 18 rotates in the annular groove 5 to perform precise bending operations on the steel wire.
