[0018] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0019] The specific embodiments are given below.

[0020] Referring to Figures 1-6 In the embodiments of the present application, a leakage-proof metal hose comprises a metal bellows 1, a first connector 2, a second connector 3 and a clamping mechanism 4, the left end of the metal bellows 1 is welded and fixed with the first connector 2, the right end of the metal bellows 1 is welded and fixed with the second connector 3, the front side of the first connector 2 is fixed with a plug-in ring 201, the outside of the plug-in ring 201 is fixed with a sealing sleeve 202, the outer diameter of the sealing sleeve 202 gradually increases from left to right, the second connector 3 is fixed with a limiting ring 301, the limiting ring 301 is fixed with a sealing ring 302, the sealing sleeve 202 and the sealing ring 302 are made of rubber, so that they have a certain elastic deformation capacity, the second connector 3 is installed with the clamping mechanism 4, the clamping mechanism 4 is used for fixing the first connector 2 and the second connector 3 together, the clamping mechanism 4 comprises a semicircular clamping shell 401, a bolt 402, a nut 403 and a pin shaft 404, the number of the semicircular clamping shell 401 is two, the two semicircular clamping shells 401 are symmetrically arranged above and below the central axis of the second connector 3, each semicircular clamping shell 401 is rotationally connected with the second connector 3 through the pin shaft 404, the two semicircular clamping shells 401 are detachably fixed through the bolt 402 and the nut 403, and the semicircular clamping shell 401 is used for clamping the outer ring of the first connector 2 and the second connector 3.
