Claims

[Scope of utility model registration request]

It includes an elastic ring between the trapezoidal holding plate and the screw with a plate, and a pull ring screwed into the screw of the screw with a plate protruding from the trapezoidal holding plate, which press and expand the elastic ring to close the pipe opening, In addition, the elastic ring is loosened by removing the extraction ring, and the entire assembly can be removed from the pipe port. Several rubber shafts are attached to the upper end of the elastic ring. These rubber shafts partially protrude from the grooves and come into contact with the edge of the tube mouth, creating stopping friction, so that when the pull ring is turned, the entire assembly It can be operated with just one hand without turning, and there are T-shaped clamps facing inwards on both sides of the concave frame at the center of the trapezoidal holding plate, and the lower flange of the pull ring is fed into the concave frame from the side of the clamp. After that, it will be wrapped by the two clamps, and when the pull ring is turned, it will move within the concave frame to prevent it from coming off or disassembling. A facing protrusion is provided, and when the screw is loosened and removed using the pull ring, the pull ring naturally rises and comes into contact with the protrusion tooth profile on the pull ring flange, producing a contact sound due to friction. A pipe port blocker for preventing dirty water, mud, corrosive gas, etc. from entering the pipe, which is characterized by giving a warning to the installer.
