Since each forming die is controlled by a separate screw, it can perform clamping operation, bending operation and loosening operation. Therefore, the above three operation actions are realized by only two screws and without guide rods (this is The important invention point of the present invention) simplifies the equipment structure to the greatest extent under the situation of ensuring the use requirements. Moreover, through the adjustable guide rollers, it can meet the bending of cables with different diameters, and can ensure the shape accuracy of its U-shaped bent horizontal legs, avoiding an inclined shape. This mode of bending enables the exact spot where it needs to be bent, avoiding wasted cables. The speed governor is adjusted by the electronic control device to control the speed of the first drive motor and the second drive motor, thereby controlling the left and right sliding speeds of the left sliding forming mold and the right sliding forming mold, which can be adjusted as required speed to bend the head of the cable.
