The clamping assembly 5 is fixedly installed on the outer surface of one end of the piston rod in the electric telescopic rod 4, and the clamping assembly 5 includes a second fixed block 10, an insert block 11, an installation cavity 12, a compression spring 13, a limit block 14, a sliding hole 15 and a clamping shaft 16. The first fixed block 7 is fixedly installed in the middle of the inner wall of the arc plate 6. A slot 9 is provided on the outer surface of the lower end of the first fixed block 7, and a clamping hole 8 is provided in the middle of the outer surface of one side of the first fixed block 7. One end of the clamping hole 8 is connected to the slot 9.

[0026] The outer surface of the lower end of the electric telescopic rod 4 is fixedly connected to the outer wall of the wheel disc 1, and the outer surface of the lower end of the second fixed block 10 is fixedly connected to the outer surface of one end of the piston rod in the electric telescopic rod 4; the plug-in block 11 is fixedly installed in the middle of the outer surface of the second fixed block 10 away from the end of the electric telescopic rod 4, the installation cavity 12 is opened inside one end of the second fixed block 10, and the sliding hole 15 is opened on the upper part of the outer surface of one side of the plug-in block 11, and the sliding hole 15 is connected to the installation cavity 12; the compression spring 13 and the limit block 14 are both located in the installation cavity 12, the clamping shaft 16 passes through the sliding hole 15, and the compression spring 13 is fixedly installed in the installation cavity 12. The outer surface of one end is fixedly connected to one end of the installation cavity 12, the outer surface of the other end of the compression spring 13 is fixedly connected to the outer surface of one side of the limit block 14, and the clamping shaft 16 is fixedly installed in the middle of the outer surface of the other side of the limit block 14; the outer wall of the plug block 11 and the slot 9 are plug-in, and the outer wall of one end of the clamping shaft 16 and the clamping hole 8 are clamped; the outer wall of the limit block 14 and the installation cavity 12 are slidably connected, and the outer surface of one side of the limit block 14 is elastically connected to one end of the installation cavity 12 through the compression spring 13, and the outer wall of the clamping shaft 16 and the sliding hole 15 are slidably connected.

[0027] It should be noted that the present invention is a steel ring positioning bracket device for the inner wall of a steel tube. After the steel ring is installed on the inner wall of the steel tube, before welding, the steel ring is limited by the steel ring support positioning piece 3, and the operation of the electric telescopic rod 4 drives the arc plate 6 to move. The arc plate 6 fixes the steel ring between the arc plate 6 and the inner wall of the steel tube to play a positioning role, thereby avoiding the steel ring from shifting during welding. First, weld the position where the steel ring is not limited by the arc plate 6, and finally dismantle the positioning bracket and then fully weld the steel ring. The arc plate 6 is provided, and the arc plate 6 and the electric telescopic rod 4 are detachably connected, which is convenient for adjusting according to the size of the steel tube. When replacing a different type of curved plate 6 and installing the curved plate 6, squeeze the clamping shaft 16 in the clamping assembly 5 so that the clamping shaft 16 enters the sliding hole 15, and the clamping shaft 16 drives the limit block 14 to squeeze the compression spring 13 in the installation cavity 12, and then insert the insert block 11 into the slot 9. When the clamping shaft 16 reaches the position of the clamping hole 8, due to the reset effect of the compression spring 13, one end of the clamping shaft 16 is driven to be clamped into the clamping hole 8, completing the installation and making it easy to disassemble. When disassembling, you only need to squeeze the clamping shaft 16 clamped in the clamping hole 8 to separate the clamping shaft 16 from the clamping hole 8, and then the curved plate 6 can be removed, which is easy to operate.
