The advantage is that by engaging the fixed pipes 3 at both ends of the joint body 1 with the pipe to be connected 2 respectively, the limiting plate 401 is extended and reset under the action of extrusion, which is conducive to limiting the interface of the pipe to be connected 2 through the reaction force of the limiting plate 401 after the fixed pipe 3 is fully engaged.

[0033] Specifically, a limit spring 4021 is movably installed inside the movable groove 402, a connecting plate 4022 is fixedly installed between the limit springs 4021, and the connecting plate 4022 is movably installed inside the movable groove 402. The advantage is that the limit spring 4021 and the connecting plate 4022 are conducive to improving the stability of the limit plate 401 during movement during extension and retraction, and avoiding reducing the installation accuracy.

[0034] Specifically, a mounting groove 301 is provided on the side of the fixed pipe 3 close to the pipe to be connected 2, a sealing ring 302 is provided inside the mounting groove 301, a sliding groove 303 is provided outside the pipe to be connected 2, and a slider 304 is provided inside the sliding groove 303.
