[0045] Working principle: when working, one person tightly fits the lower base to the damaged part of the pipe body 1, and the other person needs to rotate the support pipe 5, moves the support pipe 5 to the side close to the upper base 4, and then places the upper base 4 on the other side of the pipe body 1. The bottom of the second reciprocating lead screw 52 is aligned with the top of the upper base, the chain 3 is placed in the clamping groove 552, and the handle 51 is rotated. When one hand rotates the handle 51, the other hand holds the sleeve or moves the rod 54 to prevent the sleeve from rotating, thereby ensuring that the second reciprocating lead screw 52 drives the sleeve to move radially. The sleeve moves upward, and the bottom of the second reciprocating lead screw 52 is screwed into the top of the upper base 4. During the screwing process, if the chain 3 is tightened, stop rotating. If the bottom of the second reciprocating lead screw 52 is screwed to the bottom, the chain 3 is still loose, and the moving rod 54 needs to be rotated. The moving rod 54 moves towards the support pipe 5 until the chain 3 is tightened, and then the rotation is stopped. The support pipe 5, the support rod 53, the connecting rod, the hook clamping piece 55, the chain 3, and the lower base 2 form a pressing device, which makes the entire device stable and fixed on the outside of the pipe body 1, achieving the effect of rapid plugging. The bottom of the upper base 4 is provided with a rotating roller 42, which facilitates the adjustment of the position of the upper base 4, so that the central axes of the upper base 4 and the lower base 2 coincide. When adjusting the support pipe 5, the bottom of the second reciprocating lead screw 52 is screwed to the bottom of the upper base 4, but the chain 3 is still loose, and the moving rod 54 needs to be rotated. The support rod 53 is threadedly connected with the moving rod 54, so the moving rod 54 is rotated into the support rod 53 until the chain 3 is tightened, and then the rotation is stopped, achieving secondary adjustment.

[0046] In order to maintain the stability of the upper base 4, the first rotating block 45 needs to be rotated to drive the first reciprocating lead screw 44 to rotate, drive the connecting seat 46 to move up and down, and drive the fixed roller 43 to move up and down until the fixed roller 43 is tightly fitted to the pipe body 1, thereby preventing the upper base 4 from shaking. When the size of the pipe body 1 is changed, the position of the fixed roller 43 is adjusted to satisfy the fixation of pipe bodies 1 of various sizes, and the upper base 4 as a whole is suitable for lower bases 2 of different sizes.

[0047] Since the lower base 2 directly contacts the pipe body 1, it is necessary to maintain the fit between the lower base 2 and the pipe body 1. When the lower base 2 is damaged or rusted, it may no longer fit the pipe body 1, and when the lower base 2 needs to be replaced, the second rotating block 24 is rotated to drive the threaded rod 23 to rotate, drive the moving plate 21 to move, drive the moving plate 21 to move upward, drive the clamping column 22 to move upward, and release the fixation of the chain 3, so that replacement can be performed. When the moving plate 21 moves downward, the moving plate 21 drives the clamping column 22 to move downward to achieve the fixation of the chain 3.

[0048] Obviously, the above embodiments are only examples for clearly illustrating the present application and are not intended to limit the present application. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be enumerated, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
