[0004] In the above scheme, although there are many benefits, there are also the following disadvantages: the position of the rectangular tube is adjusted by the scale lines on the load-bearing bar so that it is located at the center of the concave block, and then the rectangular tube is fixed in the concave block. However, when adjusting the position of the rectangular tube according to the scale lines, personnel may need to manually move the rectangular tube. When the adjusted rectangular tube is fixed in the concave block, deviations may occur if the personnel's hands shake, thereby affecting the accuracy of the bending. At the same time, the movement of the two sets of bending components is achieved by two drive motors, but the method of setting up two drive motors will increase the production cost and maintenance cost of the personnel.
