[0018] Embodiment: As Figures 1-3 shown, the present utility model provides a technical solution: a simple bending structure, including a circular disc 1. A fixing column 11 is fixedly installed at the top end of the circular disc 1. Symmetrically distributed fixing blocks 12 are fixedly installed in the middle of the outer side of the fixing column 11. One end of the fixing block 12 is fixedly connected to a lower ear seat 13. An upper ear seat 14 is movably installed at the top end of the lower ear seat 13. A pin shaft 15 is slidably inserted into the middle of the circular disc 1. Symmetrically distributed steel pipes 16 are movably sleeved on the outer side of the pin shaft 15. Threaded holes 17 are opened at both ends of the pin shaft 15. A first bolt 18 is threadedly installed inside the threaded hole 17. Positioning springs 19 are fixedly installed on the outer sides of the two groups of fixing columns 11 in an array distribution. The mutually remote ends of the two groups of positioning springs 19 are fixedly connected to a positioning ring 20. The mutually remote ends of the positioning ring 20 are in contact with the outer surface of the steel pipe 16.

[0019] Symmetrically distributed upper connecting blocks 21 are fixedly installed on the outer side of the upper ear seat 14. Plug plates 22 are fixedly installed at the bottom ends of the upper connecting blocks 21. Symmetrically distributed lower connecting blocks 23 are fixedly installed on the outer side of the lower ear seat 13. Slots 24 are opened inside the lower connecting blocks 23. One end of the plug plate 22 slidably penetrates through the slot 24. A second bolt 25 is threadedly installed on the outer side of the lower connecting block 23. One end of the second bolt 25 threadedly penetrates through the lower connecting block 23 and the plug plate 22 and is threadedly installed inside the lower ear seat 13.

[0020] By adopting the above technical solution, the upper ear seat 14 and the lower ear seat 13 are positioned and docked by inserting the plug plate 22 into the slot 24, and then the second bolt 25 is installed to fix the upper ear seat 14 and the lower ear seat 13. After removing the second bolt 25, the plug plate 22 is pulled out from the slot 24, which is convenient for disassembling the upper ear seat 14, and further convenient for replacing upper ear seats 14 of different sizes for bending processing at different angles.

[0021] One end of the pin shaft 15 is fixedly connected to a connecting ring 26. A chain 27 is installed inside the connecting ring 26. One end of the chain 27 is connected to a connecting column 28. One end of the connecting column 28 is fixedly connected to the fixing column 11.

[0022] By adopting the above technical solution, the pin shaft 15 is limited and controlled by arranging the connection between the connecting ring 26 and the chain 27 and the connection between the connecting column 28 and the chain 27, preventing the pin shaft 15 from being easily lost and left without limitation when placed without limitation.

[0023] The bottom end of the lower ear seat 13 is fixedly installed with symmetrically distributed reinforcing rods 29, and one end of the reinforcing rod 29 is fixedly connected to the top surface of the circular disc 1.

[0024] By adopting the above technical solution, the support for the lower ear seat 13 and the upper ear seat 14 is strengthened by setting the reinforcing rod 29.

[0025] A U-shaped handle 30 is fixedly installed on the outer side of the fixed column 11.

[0026] By adopting the above technical solution, it is convenient to carry and move the whole structure during transportation by setting the U-shaped handle 30.

[0027] An anti-wear sleeve 31 is fixedly sleeved on one end of the U-shaped handle 30.

[0028] By adopting the above technical solution, anti-wear is carried out by setting the anti-wear sleeve 31, and the pain of the human hand holding the four corners of the U-shaped handle 30 is reduced.

[0029] Working principle: First, place the steel pipe 16 on the outer side of the fixed column 11, then use the pin shaft 15 to slide through the fixed column 11 and also through the steel pipe 16, and then use the first bolt 18 to install in the threaded hole 17 to prevent the steel pipe 16 from falling off. At the same time, rely on the action of the positioning spring 19 to push the positioning ring 20 to effectively position the steel pipe 16, which also limits the movement range of the steel pipe 16 on the pin shaft 15 and helps to stably bend. Immediately afterwards, through the use of manual and equipment, the steel pipe 16 is brought into contact with the upper ear seat 14 and bent with greater force, which is convenient for the steel pipe 16 to be bent to reduce the height or change a certain direction. The structure is ingenious, maintenance-free, and the manufacturing and use costs are also low, which is very practical. The upper ear seat 14 and the lower ear seat 13 are positioned and docked by inserting the insertion plate 22 into the slot 24, and then the second bolt 25 is installed to fix the upper ear seat 14 and the lower ear seat 13. After removing the second bolt 25, the insertion plate 22 is pulled out of the slot 24 to facilitate the removal of the upper ear seat 14, and then it is convenient to replace the upper ear seat 14 of different sizes for bending processing at different angles.

[0030] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
