[0026] Specific, sealant is used to improve the tightness of the gasket 44 and the pipe body 1, the release layer prevents the sealant from sticking, and when sealing, the release layer is torn off. When in use, the pipe body 1 is placed between the two clamping plates 3, and then the clamping plates 3 are rotated against the limiting assembly 5, so that the lower ends of the two clamping plates 3 are inclined against the pipe body 1, and the upper ends of the two clamping plates 3 remain horizontal, facilitating the plug-in cooperation of the upper plate body 42 and the clamping plate 3. The upper plate body 42 is inserted into the inside of the insertion slot 41, and then the threaded rod one 43 drives the sealing gasket 44 to move to the leakage point of the pipe body 1, so as to seal the leakage gasket through the sealing gasket 44, thereby quickly plugging the leakage point, effectively solving the problem of gas leakage, avoiding a series of potential hazards that may occur due to gas leakage, and the clamping plate 3 can be attached to pipe bodies 1 of various sizes, so that the anti-leakage assembly 4 can seal pipe bodies 1 of various diameters.
[0027] The side wall of the insertion slot 41 is provided with a slot 45, and the upper surface of the slot 45 is provided with a positioning hole 46. The two ends of the upper plate body 42 are respectively fixedly provided with a protruding layer 47, and the upper surface of the protruding layer 47 is fixedly connected with a positioning column 48.

[0032] The limiting component 5 further comprises a U-shaped support frame 51 which is slidably connected with the base 2, and two ends of the support frame 51 are respectively provided with inclined surfaces, and a threaded rotating rod two 52 is threadedly connected with the center of the support frame 51, and the top end of the threaded rotating rod two 52 is rotatably connected with the lower surface of the base 2.
[0033] Specifically, the support frame 51 is driven to slide along the base 2 by rotating the threaded rotating rod two 52, the inclined surface of the support frame 51 moves to the uppermost position to abut against the unfolded inclined end 31, so that the vertical end 32 in the unfolded state is kept horizontal to facilitate the insertion of the upper plate body 42, and when the inclined surface of the support frame 51 descends to the inside of the base 2, the clamping plate 3 is not blocked, so that the inclined end 31 and the vertical end 32 can be kept horizontal to be folded with the base 2.
