[0034] Limiting pipe 3 is rotatably connected with butt joint pipe 2, sealing groove 301 is opened with six, and sealing groove 301 is divided into two groups and opened in the two ends of the inner wall of limiting pipe 3.

[0035] Gasket 302 is fixedly connected to the inner wall of limiting pipe 3, the number of gasket 302 is equal to that of square groove 201, and the outer wall of limiting pipe 3 is fixedly connected with hand wheel 4.

[0036] Each gasket 302 is located at the inner side of each square groove 201, and the six second sealing rings 203 are matched with the six sealing grooves 301 respectively.

[0037] Metal hook 303 is fixedly connected to the side of gasket 302 away from limiting pipe 3, metal hook 303 is provided with a plurality of metal hooks, the end of metal hook 303 away from gasket 302 is provided with a chamfer, and the direction of chamfer is staggered with the direction of the two ends of limiting pipe 3.

[0038] Fixed sleeve 1: as the main component of the connecting device, for fixedly connecting two butt joint pipes 2, providing structural support for the whole connecting device.

[0039] Butt joint pipe 2: fixedly connected with fixed sleeve 1, for connecting pipeline, the square groove 201 on the surface, the first sealing ring 202 on the inner wall and the second sealing ring 203 on the outer wall realize the connection and sealing function of pipeline together.

[0040] Square groove 201: opened in the surface of butt joint pipe 2, for accommodating gasket 302, and limiting and fixing pipeline by cooperating with limiting pipe 3.

[0050] First, the application can be directly inserted into two pipes two butt pipe 2 inside, by two first sealing ring 202 sealing, the end of two pipes respectively with two fixed mechanism gasket 302 contact, metal hook 303 at this time with the pipe contact, hanging two pipe wall, then, through the hand wheel 4 drive limit pipe 3 rotation, make two limit pipe 3 drive gasket 302 connected metal hook 303 towards the chamfered end of metal hook 303 direction rotation, make metal hook 303 cut open pipe (PVC and other non-metallic pipe) part of the outer wall, make it with pipe firmly bite, make pipe can't from butt pipe 2 inside separate.

[0051] Second, when the application needs to disassemble the pipe, can be through the hand wheel 4 drive limit pipe 3 towards the first step in the opposite direction rotation, and need to turn a little more angle, make metal hook 303 separate cutting pipe groove and pipe inserted into the butt pipe 2 when the groove cut by metal hook 303, at this time can be extracted from the pipe butt pipe 2 inside, because metal hook 303 is not inverted hook structure, although will with pipe scratch, but not easy like inverted hook structure that with pipe fall off, make metal hook 303 can be reused.

[0052] Finally, it should be noted that: obviously, the above examples are only for the purpose of clearly illustrating the utility model made of example, and not limited. For those skilled in the art, on the basis of the above description can also be made in other different forms of changes or variations. Here do not need to and can't all the implementation of the way to be exhausted. By this extension of the obvious changes or variations still within the scope of the present invention.
