A support assembly 3 for supporting the movable column 2 is provided in the middle of the bottom end of the support plate 12. The support assembly 3 is composed of a movable rod 31 and a limiting shaft 32. The movable rod 31 is located at the bottom end of the upper support plate 12. The bottom end of the movable column 2 is fixedly connected to one end of the top of the movable rod 31. A convex hole is opened at one end of the bottom of the movable rod 31. The limiting shaft 32 passes through the convex hole. The top end of the limiting shaft 32 is fixedly connected to the middle of the bottom end of the upper support plate 12, so that one end of the movable rod 31 can be movably sleeved on the limiting shaft 32. At the same time, the limiting shaft 32 can support and limit the movable rod 31, and enable the movable rod 31 to drive the movable column 2 to move along the arc inside the arc hole. A driving assembly 4 for driving the supporting assembly 3 to rotate is provided at the top of the lower support plate 11. The driving assembly 4 is composed of a driven gear 41, four forward and reverse motors 42 and four driving gears 43. The driven gear 41 is fixedly connected to one end of the bottom of the movable rod 31, and the four forward and reverse motors 42 are all fixedly installed on the top of the lower support plate 11. The four forward and reverse motors 42 are all electrically connected to an external power supply through an external switch. The four driving gears 43 are respectively fixedly connected to the ends of the power shafts of the four forward and reverse motors 42, and the four driving gears 43 are all meshed with the driven gear 41. When the power shafts of the four forward and reverse motors 42 drive the four driving gears 43 to rotate in the same direction, the four driving gears 43 cooperate to drive the driving gears 43 to drive the movable rod 31 to rotate, so that the movable rod 31 can drive the movable column 2 to move along the arc;

[0019] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5A resisting column 51 is fixedly connected to the middle of the top of the upper support plate 12, and an auxiliary support column 55 is fixedly connected to one end of the top of the upper support plate 12. The resisting column 51 and the auxiliary support column 55 can resist the metal parts. The bottom end of the protractor 52 contacts the top of the resisting column 51, and the resisting column 51 can support the protractor 52. A square block 53 is fixedly connected to the middle of the top of the resisting column 51. A square hole is opened at the top of the protractor 52. The square block 53 passes through the square hole opened at the top of the protractor 52, and the protractor 52 can be positioned so that it cannot be deflected. A screw 54 is threadedly inserted in the middle of the top of the square block 53, and the bottom end of the screw 54 resists the top of the protractor 52, thereby The protractor 52 is fixedly mounted on the abutment column 51 so that the center position of the protractor 52 corresponds to the abutment column 51. The operator holds the metal piece and passes it through the bottom of the protractor 52. When the top of one side of the metal piece fits with one side of the auxiliary support column 55 and the middle of the other side fits with the abutment column 51, the driving gear 43 drives the movable rod 31 to rotate, and the movable rod 31 drives the movable column 2 to move along the arc, and at the same time, the other side of the metal piece is abutted to push the metal piece to deflect around the abutment column 51 as the axis, thereby bending it.
