[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the limit structure can limit the angle of the steel pipe by limiting the bending column 36. The limit structure includes: a base column 40, an adjustment ring 42, a side plate 44 and a stop rod 46. The base column 40 is fixedly connected to the top of the bottom plate 20, the adjustment ring 42 is rotatably connected to the wall of the base column 40, the side plate 44 is set on the wall of the adjustment ring 42, and the stop rod 46 is fixedly connected to the side wall of the side plate 44. The connecting rod 32 can contact the side wall of the stop rod 46 by rotating.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the base column 40 is in the shape of a hollow cylinder, the rotating motor 29 is fixedly connected to the cavity of the base column 40, the adjusting ring 42 is in the shape of a circular ring, the side plate 44 is in the shape of a rectangular plate, and the limit structure also includes a rotating groove 41, a bottom rod 43, a finger block 45 and an angle groove 51.

[0034] When in use, the angle groove 51 is engraved with an angle number. Before use, first lift the slider 48 upwards and move the side plate 44 to the desired angle. When being moved, the side plate 44 will rotate with the adjustment ring 42 as the center of the circle. The side plate 44 can drive the finger block 45 to indicate the number in the angle groove 51. After adjusting to the desired angle, release the slider 48. The slider 48 and the clamping column 49 will enter the locking groove 50 at the corresponding position due to gravity, thereby fixing the position of the side plate 44. After the adjustment is completed, The steel material to be bent is placed between the fixing plate 28 and the limiting plate 23, and the steel pipe is still between the bending column 36 and the limiting plate 23. At this time, the power supply is turned on.

[0038] In summary, by providing an adjustment structure, the positions of the bending column 36 and the fixing plate 28 can be adjusted so that steel materials of different sizes can be fixed on the upper plate 22, thereby making the device have a wider range of use.

[0039] Working principle: An angle number is engraved in the angle groove 51. Before use, first lift the slider 48 upward and move the side plate 44 to the desired angle. When the side plate 44 is moved, it will rotate with the adjustment ring 42 as the center of the circle. The side plate 44 can drive the finger block 45 to indicate the number in the angle groove 51. After adjusting to the desired angle, release the slider 48. The slider 48 and the clamping column 49 will enter the locking groove 50 at the corresponding position due to gravity, thereby fixing the position of the side plate 44. After the adjustment is completed, The steel to be bent is placed between the fixing plate 28 and the limiting plate 23 and the steel pipe is still between the bending column 36 and the limiting plate 23. At this time, the power is started. When the power is turned on, the rotating motor 29 will drive the starting column 30 to rotate, and the starting column 30 will drive the belt ring 31 to rotate. The belt ring 31 will drive the connecting rod 32, the belt rod 33, the second adjustment block 35 and the bending column 36 to rotate at the same time. The bending column 36 can bend the steel along the wall surface during rotation. When the connecting rod 32 rotates to contact the side wall surface of the blocking rod 46, it stops rotating to complete the bending of the steel.
