A control component for adjustment is fixedly connected to the right side of the box body 1. The control component includes two rotating rods 3. The two rotating rods 3 are made of metal material, and their left ends are connected to the right end of the box body 1 through a rotating connection structure to ensure flexible and stable rotation. A connecting rod 4 is fixedly connected to the adjacent side of the two rotating rods 3. The connecting rod 4 is also made of steel and serves to connect the two rotating rods 3 so that their rotation can be kept synchronized, thereby enhancing the stability of the entire device during the adjustment process;
[0024] The right end of the rotating rod 3 is fixedly connected to a push handle 5, which is ergonomically designed to facilitate the operator to comfortably apply force to push the entire device. The right end of the box body 1 is rotatably connected to an electric push rod 6. The electric push rod 6 is a high-performance power device, and its driving end is fixedly connected to the bottom end of the rotating rod 3 through a firm connection. When the electric push rod 6 is started, it can accurately drive the rotating rod 3 to rotate, thereby changing the height and angle of the box body 1 to adapt to different work requirements. Two support blocks 7 are fixedly connected to the left side of the top of the box body 1. The support block 7 is made of cast iron material and provides stable support for the rotating column 8. The adjacent side of the two support blocks 7 is rotatably connected to a rotating column 8. The rotating column 8 can flexibly rotate between the support blocks 7, which may assist in the placement of steel bars and play a certain guiding role in some cases. A loading plate 9 is fixedly connected to the middle of the top of the box body 1;
[0025] The loading plate 9 is made of steel plate and provides a stable placement platform for the steel bars that need to be bent. A fixed block 10 is fixedly connected to the front side of the top of the loading plate 9. The fixed block 10 is made of an alloy material and is used to fix and support the adjustment rod 11. The internal thread of the fixed block 10 is connected to the adjustment rod 11. The adjustment rod 11 is made of high-quality steel with a specially treated surface and precise threads. It can be moved back and forth by rotation. The other end of the adjustment rod 11 is fixedly connected to a control disk 12.

The top of the rotating disk 15 is provided with multiple mounting holes 16, precisely machined to precise dimensions for mounting various components. A bending shaft 17 is threadedly connected to the interior of the middle mounting hole 16. Made of a special alloy material with high strength and wear resistance, this shaft 17 works in conjunction with a bending rod 18 to bend the rebar. A bending rod 18 is also threadedly connected to the interior of one of the outer mounting holes 16. This bending rod 18 is also made of a special material and works in conjunction with the bending shaft 17 to precisely bend the rebar.
[0026] Reference Figures 2 to 4The front end of the housing 1 is rotatably connected to a protective switch assembly. This assembly includes a protective door 19, made of sheet metal. One side of the door is connected to the front interior of the housing 1 via a secure rotatable connection. This effectively protects the components inside the housing 1, preventing dust and debris from entering and affecting the normal operation of the equipment. A handle 20 is fixedly connected to the front of the protective door 19. This handle 20 is well-designed and convenient for the operator to open and close the door 19. A loading tray 21, made of steel, is fixedly connected to the bottom end of the rotating disk 15. The loading tray 21 serves as a connection and power transmission mechanism. A motor 22 is fixedly connected to the bottom end of the housing 1. This high-performance power device provides a powerful source of power for the entire device. The drive end of the motor 22 is fixedly connected to a rotating plate 23, made of metal, which rotates as the motor 22 rotates. The bottom end of the rotating plate 23 is rotatably connected to the top right interior end of the housing 1. This rotatable connection ensures stable rotation of the rotating plate 23. The top of the rotating plate 23 is fixedly connected to two fixed columns 24. The fixed columns 24 are made of steel and move under the drive of the rotating plate 23. The top of the box body 1 is rotatably connected to a connecting plate 25. The connecting plate 25 is made of alloy steel and plays the role of transmitting power. The outside of the connecting plate 25 is provided with a plurality of movable holes 26. The outside of the fixed columns 24 is slidably connected to the inside of the movable holes 26, allowing the fixed columns 24 to slide smoothly therein. The inside of the connecting plate 25 is fixedly connected to a limiting rod 27. The limiting rod 27 plays the role of connecting and transmitting power. The bottom end of the loading tray 21 is fixedly connected to the top of the limiting rod 27. The fixed connection ensures the effective transmission of power. The outside of the limiting rod 27 is rotatably connected to the inside of the top of the box body 1. The rotational connection ensures the stable rotation of the loading tray 21.
[0027] Working Principle: First, the operator pushes the entire device using handle 5, which then drives the rotating rod 3 to rotate. The rotation of the rotating rod 3 is synchronized by the connecting rod 4, and the universal wheel 2 rolls on the ground, allowing the box 1 to move to the appropriate position. When the height of the device needs to be adjusted, the electric push rod 6 is activated. The driving end of the electric push rod 6 drives the rotating rod 3 to rotate, thereby changing the height and angle of the box 1.
[0028] Place the steel bar to be bent on the loading plate 9, and rotate the control disk 12 to drive the adjusting rod 11 to rotate. The adjusting rod 11 pushes the limit plate 14 to move. The rotating block 13 on the limit plate 14 assists the limit plate 14 to move smoothly, and the limit plate 14 limits and fixes the steel bar.
[0029] Then, the motor 22 is started, driving the rotating plate 23. The fixed posts 24 on the rotating plate 23 rotate with it, sliding within the movable holes 26 on the outside of the connecting plate 25. The sliding of the fixed posts 24 causes the connecting plate 25 to intermittently rotate. The connecting plate 25, via its internal limit rods 27, drives the loading plate 21 to rotate, which in turn drives the rotating plate 15 to intermittently rotate. The bending shaft 17 and bending rod 18 at the top of the rotating plate 15 cooperate to bend the rebar. Different bending shafts 17 and bending rods 18 can be replaced within the assembly holes 16 to accommodate different rebar thicknesses.
[0030] When maintenance or inspection is required inside the device, the protective door 19 is opened by the handle 20 , and components such as the motor 22 inside the box body 1 can be operated.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
