Tubing pipe sizing tool

Abstract

A tubing pipe sizing tool is provided, comprising a main body, a measuring portion, a handle-installing hole, a bump portion, and a handle. The measuring portion is provided on a first part of the main body in a first direction. The handle-installing hole is provided on a second part of the main body in a second direction perpendicular to the first direction. The bump portion is provided around an opening of the handle-installing hole. The handle is configured to engage the handle-installing hole and facilitate pipe sizing. The main body may have a cylindrical shape, and the bump portion facilitates to handle the tool.

1 . A tubing pipe sizing tool comprising:
 a main body;   a measuring portion provided on a first part of the main body in a first direction;   a handle-installing hole provided on a second part of the main body in a second direction perpendicular to the first direction; and   a handle engaging the handle-installing hole fixedly and facilitate pipe sizing,   wherein the main body has a cylindrical shape,   wherein the measuring portion is provided along a central axis of the cylindrical shape of the main body,   wherein the measuring portion comprises a measuring cylinder portion protruding in the first direction for measuring an inner diameter of an external pipe.   
     
     
         2 . The tubing pipe sizing tool of  claim 1 , wherein the handle-installing hole is bored into a side of the cylindrical shape of the main body, wherein the handle-installing hole comprises a helical female thread provided on the inner surface of the handle-installing hole. 
     
     
         3 . The tubing pipe sizing tool of  claim 2 , wherein the handle comprises a helical male thread on an end portion of the handle, so as to engage the helical female thread of the handle-installing hole. 
     
     
         4 . The tubing pipe sizing tool of  claim 1 , wherein the main body, the measuring portion, and the handle-installing hole are made monolithically. 
     
     
         5 . The tubing pipe sizing tool of  claim 4 , wherein the main body, the measuring portion, the handle-installing hole, and the handle are made of metal. 
     
     
         6 . The tubing pipe sizing tool of  claim 5 , wherein the measuring portion further comprises a cusp-cut cone portion provided on an end of the measuring cylinder portion. 
     
     
         7 . The tubing pipe sizing tool of  claim 6 , wherein the measuring cylinder portion is formed so as to meet the main body perpendicularly. 
     
     
         8 . The tubing pipe sizing tool of  claim 5 , further comprising a roughened surface portion provided on an outer surface of the main body. 
     
     
         9 . The tubing pipe sizing tool of  claim 8 , wherein the roughened surface portion comprises a plurality of elongated bump line portions forming a criss-cross pattern. 
     
     
         10 . The tubing pipe sizing tool of  claim 8 , wherein the plurality of elongated bump line portions are configured to be hold by a finger with a certain friction.
