[0009] As an improvement to the above technical solution: the outer side surface of the movable connecting pipe sleeve is provided with a fixing sleeve, and the outer side surface of the fixing sleeve is provided with a plurality of anti-slip convex strips in a circular array.

[0010] Beneficial effects of the utility model:

[0011] 1. When repairing a damaged part of a pipe, first insert the sealing strip layer into the limiting slot through the limiting strips at both ends, so that the sealing strip layer is connected to the bottom of the arc plate, then insert the movable connecting pipe sleeve into the outside of the pipe, and at the same time move the movable connecting pipe sleeve toward the damaged part of the pipe, so that the arc plate is coaxially aligned above the damaged part, and then by rotating the threaded rod, the arc plate is driven to move toward the damaged part, so that the sealing strip layer squeezes the damaged part, so that the damaged part of the pipe can be repaired quickly, saving time and effort;

[0012] 2. Pull out the connection frame by pulling the plate, and then repeatedly rotate the movable connection sleeve left and right, so that the movable connection sleeve can synchronously drive the arc plate to rotate, so that the inner side of the arc plate can be repeatedly rotated left and right to further squeeze the sealing strip layer on the damaged part of the pipe, which has a good sealing effect on the pipe.

[0013] 3. When the curved plate moves to the damaged part of the pipe, the damaged part can be squeezed and repaired by the sealing strip layer. The curved plate can limit the squeezed sealing strip layer to the damaged part. Compared with the existing technology, it can avoid placing the sealing strip layer on the damaged part of the pipe first and then squeezing the sealing strip layer to the damaged part to repair it. It can also avoid that when the sealing strip layer is first placed on the damaged part of the pipe during pipeline repair, the liquid pressure in the pipe is too high, causing leakage from the damaged part through the sealing strip layer.

The curved plate 8 can limit the squeezed sealing strip layer 9 at the damaged part. Compared with the existing technology such as the pipe repair device with publication number CN220749450U, it is avoided that the sealing strip layer 9 is first placed at the damaged part of the pipe and then squeezed to the damaged part to repair it. It is avoided that when the sealing strip layer 9 is first placed at the damaged part of the pipe during pipe repair, the liquid pressure in the pipe is too high, causing leakage from the sealing strip layer 9 at the damaged part.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
