[0032] Working principle: Before using the device, first, select the required bending block 9 and accurately place it into the card slot above the card slot plate 8. Subsequently, pass the limiting block 10 through the hole above the bending block 9 to ensure its stable fixation. Next, according to the bending requirements, accurately move the L-shaped blocks 11 on both sides to the required bending distance on both sides.

During the operation, the distance between the two sides of the bent steel bar can be flexibly adjusted according to actual needs to achieve the best bending effect. And through the design of the buffer mechanism 2, the steel bar is properly placed above the L-shaped block 11. During this process, the outermost part of the steel bar is affected by the pressing plate 202 and remains in a compact state under the extrusion of the first spring 203. In addition, the rolling of the roller 205 above the U-shaped block 204 makes the steel bar more smooth and easy to operate during the bending process. At the same time, the buffer plate 207 will move downward synchronously during the downward movement to cooperate with the bending action. When the bending block 9 moves upward, the second spring 208 will play its role and push the buffer plate 207 back to the initial position. This design ensures the accuracy and stability of the bending process, improves work efficiency and product quality.
