The inside of the ring body and causing it to rise creates a force from the inside to the outside. The guiding groove makes the tapered block relatively stable with the position of the rising block and the moving track. The limit steel plate connects the annular body to the central screw and becomes a whole, so that it is convenient to insert into the metal tube. When the center screw is tightened, the limit steel plate will move with the taper block, which will generate a pulling force, which is favorable for the flushing ports of the ring body to be flush. The two tapered blocks and two or more rising blocks are matched and slid by the inclined surface to generate the tensile force. If the matching position or angle is improper, the strength and stability of the connection will be affected, and the guiding groove and the limiting steel plate can effectively improve. these questions.

The connector is a body having two or more plug connectors that can be coupled to the port member. Connections with the same or different specifications and the number of plug connectors allow for a variety of port connections.

The pipe body member is an annular body which can be sleeved on the pipe body to be connected and has a notch, and a screw for tightening the notch is provided at the notch, and one or more of the ring body is provided on the ring body. Plug connector for port connector.

The plug connector is a convex portion with a central screw through hole on the body, and the port member is connected to the plug connector through the center screw, and only the bottom portion of the taper block worn on the center screw is inserted and fixed with the convex portion, and is tight When the center screw is fixed, the tapered block can be pushed from the side into the annular body. The conical block is simultaneously inserted into the annular body from both sides, and a relatively uniform and stable tensile force can be generated at both ends of the annular body.

The pipe body member and the port member of the invention do not cause damage to the metal pipe when connecting the metal pipe, and only the pipe mouth is cut flush, and no special processing is required, which provides convenience for replacing the metal pipe and reconstructing the frame.
