[0021] The positioning device 2 includes a supporting cavity 9, a sealing plate 10, a handle 11, a reset spring 12, a gasket 13 and a limiting plug 14. The sealing plate 10 is fixedly mounted at the inner front end of the supporting cavity 9. The limiting plug 14 is slidably inserted in the inner center of the sealing plate 10 and the supporting cavity 9. The gasket 13 is fixedly mounted on the outer ring of the limiting plug 14 close to the sealing plate 10, and the reset spring 12 is fixedly mounted between the gasket 13 and the sealing plate 10. The handle 11 is fixedly mounted at the front end center of the limiting plug 14. The elasticity of the reset spring 12 can drive the limiting plug 14 to be inserted into the square hole inside the positioning bolt 5.
[0022] A slot matching the support cross bar 16 is provided inside the support sleeve 6 , allowing the support sleeve 6 to slide on the support cross bar 16 .
[0023] The support sleeve 6 is slidably sleeved on the outer ring of the support crossbar 16, the protective sleeve 4 is slidably sleeved on the extension rod 8, and the support cavity 9 is fixedly installed on the top front end of the support sleeve 6 to support the limiting rod 14 to perform limiting work.

[0025] The positioning bolt 5 is vertically aligned with the positioning hole 15 , so that the positioning bolt 5 can be inserted into the positioning hole 15 .
[0026] Working principle: during use, when the spacing between the two arc bolts 7 needs to be adjusted, the handle 11 can be pulled toward the front end until the limiting plug rod 14 is moved out of the square hole inside the positioning bolt 5, so that the positioning bolt 5 can be released. At the same time, the positioning bolt 5 can be screwed and rotated until the positioning bolt 5 is moved out from the inside of the positioning hole 15, and the supporting sleeve 6 can be released. Subsequently, the arc bolt 7 can be pulled toward the end away from the protective sleeve 4, so that the spacing between the two arc bolts 7 can be enlarged, and the supporting sleeve 6 is slidably sleeved on the supporting cross bar 16, so that the arc bolt 7 can be supported to move along a straight line, thereby improving the movement accuracy of the arc bolt 7. Subsequently, when the supporting sleeve 6 moves to the specified position, the positioning bolt 5 can be driven to align with the positioning holes 15 at different positions, and then the positioning bolt 5 is screwed and rotated until the positioning bolt 5 is inserted into the inside of the positioning hole 15, so that the supporting sleeve 6 can be limited in positioning to prevent the arc bolt 7 from sliding again, and when the positioning bolt 5 is screwed to the positioning hole 15 When the handle 11 is in the inner part, the square hole at the front end of the positioning bolt 5 can be driven to rotate to align with the limiting plug rod 14. After that, the handle 11 can be released, and the elasticity of the return spring 12 can drive the gasket 13 to reset. Moreover, when the gasket 13 moves, it can also drive the limiting plug rod 14 to move, so that the limiting plug rod 14 can be inserted into the square hole inside the front end of the positioning bolt 5 to prevent the positioning bolt 5 from loosening, thereby completing the work of adjusting the spacing between the two arc bolts 7 and synchronizing the positioning of the positioning bolt 5. When the device is in use, the arc bolt 7 can slide on the outer ring of the supporting cross bar 16 through the supporting sleeve 6, so that the two arc bolts 7 can be supported for adjustment, which is convenient for the arc bolt 7 to limit the position of different pipes, and the positioning bolt 5 is adapted to the positioning hole 15, so that the arc bolt 7 can be limited in positioning. At the same time, the limiting plug rod 14 is inserted into the square hole inside the front end of the positioning bolt 5, so that the positioning bolt 5 can be limited in positioning, thereby preventing the positioning bolt 5 from loosening during subsequent use, thereby completing the work.
