[0015] As a further embodiment of the present invention: a cross clamp cavity is fixedly connected to the middle of the inner side of the spiral rotating rod, and a cross clamp rod is slidably connected to the inner side of the cross clamp cavity.

[0016] Compared with the prior art, the beneficial effects of the present invention are: it facilitates the device to perform secondary stretching and rounding, facilitates the stretching of circles of different sizes, and facilitates clamping and fixing of the rounded items during the rounding process to prevent the rounded items from falling off the device.

[0017] 1. Through the set rounding mechanism, during rounding, the first motor drives the first gear fixedly connected to the output end to rotate. The rotating first gear drives the first and second adjusting turntables fixedly connected to the outside of the gear connecting rod to rotate synchronously through the gear connecting rod meshing at the bottom end. This causes the adjusting arc grooves fixedly connected to one side of the first and second adjusting turntables to rotate and move, thereby causing the first and second shrinking support rods, which are engaged with the adjusting arc grooves, to slide outward along the positioning slide grooves fixedly connected to one side of the first and second positioning plates. This causes the rounding arc plate fixedly connected to the outside of the first and second shrinking support rods to move outward and engage in the inner cavity wall of the item to be rounded, thus rounding the item. When the connecting storage plate in the middle of the supporting arc plate slides outward, causing the adjusting spiral gear connected to one side of the connecting storage plate to engage with the inner wall of the drive gear ring, the second motor is activated. The second motor, through the second gear fixedly connected to the output end and the annular tooth groove meshing with the outer side of the second gear, drives the drive gear ring fixedly connected to the outer side of the annular tooth groove to rotate. The rotating drive gear ring drives the adjusting spiral gear connected to the inner side to rotate. The rotating adjusting spiral gear drives the push sliders on both sides to slide inward synchronously, pressing the bottom of the folding push frame plate fixedly connected to the top of the push slider. This causes the supporting arc plate fixedly connected to the outer side of the folding push frame plate to continue sliding outward, thereby driving the supporting arc plate to continue sliding outward. The fixed U-shaped corrugated suction tube slides outward along the pull rod fixed to one side of the connecting storage plate. This causes the main suction rubber plug fixed at the end of the pull rod to slide from one position to another inside the U-shaped corrugated suction tube. The suction pressure generated by the main suction rubber plug sliding towards the bottom of the connecting storage plate due to the pull rod will pass through the through hole connecting the U-shaped corrugated suction tube and the rubber suction cup, causing the air inside the rubber suction cup to flow into the U-shaped corrugated suction tube. This causes the surface of the rubber suction cup to adhere to the object to be rounded due to the air pressure generated by the evacuation of the air inside the rubber suction cup. Simultaneously, due to the suction pressure, multiple auxiliary suction rubber plugs slidably connected inside the U-shaped corrugated suction tube... Under the pressure of the water flow between the auxiliary suction rubber plugs, the rubber plugs slide rapidly along the inner wall of the U-shaped corrugated suction pipe in the direction of the air pressure flow, drawing air from the other rubber suction cups fixedly connected to the U-shaped corrugated suction pipe. This causes the other rubber suction cups to simultaneously grip the object to be rounded, holding it in place. As the rounding plate slides outward, it simultaneously drives the magnetic retraction connecting rod, which is slidably connected to the inner cavities of the first and second retraction support rods, to slide outward. This prevents the rounding plate from sliding outward too far and causing wobbling. The folding push frame plate pushes the rounding plate to round the object to be rounded, facilitating secondary extension and rounding of the device, making it easy to expand circles of different sizes.

[0018] 2. When clamping the object to be rounded using the clamping and fixing mechanism, as the first retractable support rod slides outward along the positioning groove, it drives the spiral rod connected to the middle of the first retractable support rod to slide upward along the spiral hole in the middle of the spiral hole fixing plate fixed at the top of the inner side of the positioning groove. The spiral hole drives the upward-sliding spiral rod to rotate, thereby driving the telescopic column rod slidably connected to the top of the outer side of the spiral rod to slide upward. At the same time, it drives the adjusting gear block fixedly connected to the top of the spiral rod to rotate. Thus, through the connecting tooth groove meshing with the outer side of the adjusting gear block, the telescopic arc plate fixedly connected to the outer side of the connecting tooth groove slides outward and locks onto the surface of the object to be rounded, clamping the object to be rounded. This facilitates clamping and fixing the object during the rounding process and prevents the object from falling off the device. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0029] Please refer to a universal adjustable circular support device. Figures 1-7 In this embodiment of the invention, the rounding mechanism 2, which is set on one side of the top of the device, is inserted into the cavity of the cylindrical item to be rounded. Then, the first motor 219 drives the first gear 220, which is fixedly connected to the output end, to rotate. This drives the gear connecting rod 210, which is meshed with the bottom end of the first gear 220, to rotate. This drives the first adjusting turntable 21 and the second adjusting turntable 212, which are fixedly connected to the outside of the gear connecting rod 210, to rotate synchronously. This pushes the first shrinking support rod 25 and the second shrinking support rod 29 to slide outward along the positioning slide groove 26 through the adjusting arc groove 22. This pushes the rounding arc plate 24, which is fixedly connected to the outside of the first shrinking support rod 25 and the second shrinking support rod 29, to slide outward and be inserted into the cavity wall of the circular item, thus expanding the item. When the first shrinking support rod 25 slides outward, it drives the clamping fixing mechanism 3 to extend outward and clamp onto the outer wall of one end of the item, thus fixing the item to be rounded.

[0030] During the rounding process, the first motor 219 drives the first gear 220, which is fixedly connected to the output end, to rotate. The rotating first gear 220, through the gear connecting rod 210 meshing at the bottom end, drives the first adjusting turntable 21 and the second adjusting turntable 212, which are fixedly connected to the outside of the gear connecting rod 210, to rotate synchronously. This causes the adjusting arc groove 22, which is fixedly connected to one side of both the first adjusting turntable 21 and the second adjusting turntable 212, to rotate and move. This causes the first retractable support rod 25 and the second retractable support rod 29, which are engaged with the adjusting arc groove 22, to slide outward along the positioning slide groove 26, which is fixedly connected to one side of both the first positioning plate 23 and the second positioning plate 214. This causes the rounding arc plate, which is fixedly connected to the outside of the first retractable support rod 25 and the second retractable support rod 29, to move outward. 24 moves outward and gets stuck in the inner wall of the object to be rounded, expanding the object. When the connecting storage plate 27 in the middle of the rounding plate 24 slides outward, causing the adjusting spiral gear 28 connected to one side of the connecting storage plate 27 to get stuck on the inner wall of the drive gear ring 211, the second motor 222 is started. The second motor 222 drives the drive gear ring 211, which is fixedly connected to the output end of the second gear 223 and the annular tooth groove 224 meshing with the outer side of the second gear 223, to rotate. The rotating drive gear ring 211 drives the adjusting spiral gear 28 meshing with the inner side to rotate. The rotating adjusting spiral gear 28 drives the push sliders 217 connected to both sides to slide inward synchronously. The movement of the sliding block 217 compresses the bottom of the folding push frame plate 218, which is fixedly connected to the top of the sliding block 217. This causes the supporting arc plate 24, which is fixedly connected to the outer side of the folding push frame plate 218, to slide outward. This causes the U-shaped corrugated suction pipe 225, which is fixedly connected to the supporting arc plate 24, to slide outward along the pull rod 230, which is fixedly connected to one side of the inner side of the connecting storage plate 27. This causes the main suction rubber plug 229, which is fixed at the end of the pull rod 230, to slide from one position to another inside the U-shaped corrugated suction pipe 225. The suction pressure generated by the main suction rubber plug 229 sliding towards the bottom of the inner side of the connecting storage plate 27 due to the pull rod 230 will be transmitted through the connection between the U-shaped corrugated suction pipe 225 and the rubber suction cup 228. The air inside the rubber suction cup 228 flows into the U-shaped corrugated suction pipe 225 through the hole, causing the surface of the rubber suction cup 228 to adhere to the object to be rounded due to the air pressure generated by the evacuation of the air inside the rubber suction cup 228. Simultaneously, due to the suction pressure, multiple auxiliary suction rubber plugs 226 slidably connected inside the U-shaped corrugated suction pipe 225 slide rapidly along the inner wall of the U-shaped corrugated suction pipe 225 in the direction of the suction pressure flow under the increased pressure of the water flow between the auxiliary suction rubber plugs 226. This draws air from the other rubber suction cups 228 fixedly connected to the U-shaped corrugated suction pipe 225, causing the other rubber suction cups 228 to also simultaneously adhere to the object to be rounded, thus holding the object in place.As the supporting arc plate 24 slides outward, it simultaneously drives the inner cavities of the first and second retractable support rods 25 and 29, which are slidably connected, to slide outward. This prevents the supporting arc plate 24 from sliding too far outward and causing wobbling. The folding push frame plate 218 then pushes the supporting arc plate 24 to round the object to be rounded.

[0031] The first retractable support rod 25 and the second retractable support rod 29 are concave in shape in the side view. Magnetic retractable connecting rods are slidably connected to the cavity walls at both ends of the first retractable support rod 25 and the second retractable support rod 29. The outer side of the magnetic retractable connecting rod is slidably connected to the inner side of the first retractable support rod 25 and the second retractable support rod 29, which helps to prevent the tendency of the arc plate 24 to extend during the second extension from being hindered.

[0032] A U-shaped corrugated suction pipe 225 is fixedly connected to the middle of the inner side of the supporting arc plate 24, and multiple rubber suction cups 228 are fixedly connected to the middle of the outer surface of the supporting arc plate 24. Driven by the outward extension of the folding push frame plate 218, the supporting arc plate 24 slides outward away from the connecting storage plate 27, thereby causing the U-shaped corrugated suction pipe 225, which is fixedly connected to the supporting arc plate 24, to slide along the pull rod 230, which is slidably connected to one side of the bottom end. This causes the main suction rubber plug 229, fixed at the end of the pull rod 230, to slide from one position to another within the inner cavity of the U-shaped corrugated suction pipe 225. The suction pressure generated by the main suction rubber plug 229 sliding towards the bottom end of the inner cavity of the connecting storage plate 27 due to the pull rod 230 will pass through the through hole connecting the U-shaped corrugated suction pipe 225 and the rubber suction cups 228, causing the air inside the rubber suction cups 228 to... Air flows into the U-shaped corrugated suction pipe 225, causing the rubber suction cup 228 to adhere to the surface of the object to be rounded due to the air pressure generated by the evacuation of air inside the rubber suction cup 228, adhering and fixing it to the object. Simultaneously, due to the suction pressure, multiple auxiliary suction rubber plugs 226, which are slidably connected to the inner side of the U-shaped corrugated suction pipe 225, slide along the inner wall of the U-shaped corrugated suction pipe 225 in the direction of the suction pressure flow. This draws air from the other rubber suction cups 228 fixedly connected to the U-shaped corrugated suction pipe 225, causing the other rubber suction cups 228 to also simultaneously adhere to the object to be rounded, fixing the object in place. This facilitates simultaneous suction of the object to be rounded during rapid rounding. The larger the arc of the rounding, the tighter the suction force, which helps prevent the object to be rounded from separating from the rounding device due to the loose clamping.

[0033] When multiple auxiliary suction rubber plugs 226 slide towards one end within the inner cavity of the U-shaped corrugated suction pipe 225, the combination of air pressure and water flow between the plugs helps prevent changes in the distance between the plugs as the auxiliary suction rubber plugs 226 slide along the U-shaped corrugated suction pipe 225 towards one end. At the same time, the water flow also increases the humidity within the inner cavity of the U-shaped corrugated suction pipe 225, which in turn increases the air pressure within the inner cavity, thus facilitating rapid sliding towards one end under the suction pressure.

[0034] When the first adjusting turntable 21 and the second adjusting turntable 212 rotate, they will drive different positions inside the adjusting arc groove 22 to push the column block fixedly connected to one side of the first contraction support rod 25 and the second contraction support rod 29, thereby pushing the first contraction support rod 25 and the second contraction support rod 29 to slide outward.

[0035] One side of the drive gear ring 211 is rotatably connected to the second adjusting turntable 212. When the connecting storage plate 27 slides, the drive gear ring 211 limits the sliding trajectory of the connecting storage plate 27, while the drive gear ring 211 drives the folding push frame plate 218 to extend.

[0036] Two sets of spiral grooves with opposite patterns are fixedly connected to the two ends of the outer surface of the adjusting spiral rod 28. When the adjusting spiral rod 28 rotates, the push sliders 217, which are slidably connected to both ends of the outer surface of the adjusting spiral rod 28, slide towards the middle of the adjusting spiral rod 28 in sync.

[0037] When clamping the item to be rounded, as the first retractable support rod 25 slides outward along the positioning groove 26, it drives the spiral rod 34, which is rotatably connected in the middle of the first retractable support rod 25, to slide upward along the spiral hole in the middle of the spiral hole fixing plate 33, which is fixedly connected to the top of the inner side of the positioning groove 26. The spiral hole drives the upward sliding spiral rod 34 to rotate, thereby driving the telescopic column rod 36, which is slidably connected to the top of the outer side of the spiral rod 34, to slide upward. At the same time, it drives the adjusting gear block 37, which is fixedly connected to the top of the spiral rod 34, to rotate. Thus, through the connecting tooth groove 38 meshing with the outer side of the adjusting gear block 37, the telescopic arc plate 32, which is fixedly connected to the outer side of the connecting tooth groove 38, slides to the outer side of the clamping arc cavity plate 31 and clamps onto the surface of the item to be rounded, thus clamping the item to be rounded.

[0038] A cross clamp rod is slidably connected to the middle of the inner side of the spiral rotating rod 34. The top of the cross clamp rod is fixedly connected to the middle of the adjusting gear rotating block 37. When the spiral rotating rod 34 drives the telescopic column rod 36 to slide upward, it drives the cross clamp rod to slowly slide out of the cross clamp cavity in the middle of the spiral rotating rod 34.

[0039] The bottom end of the spiral rod 34 is detachably snapped into the ground at the middle of the inner side of the first retractable support rod 25, and the size of the inner side of the spiral hole fixedly connected at the middle of the top of the spiral hole fixing plate 33 matches the size of the outer side of the spiral block fixed on the outer side of the spiral rod 34.

[0040] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
