Abstract

A pipe disassembling tool includes a first arm and a second arm pivotally connected with each other by a pin. The first arm and the second arm respectively have a first connecting portion and a second connecting portion formed on a first end of each of the first arm and the second arm. A torsion spring is sleeved on the pin and has two opposite ends respectively abutting against the first arm and the second arm to make the first arm and the second arm abut each other when the tool is in an original condition. A first disassembling portion is formed on a second end of the first arm and a second disassembling portion is formed on a second end of the second arm for user to detach the pipe.

Claims

1. A pipe disassembling tool comprising:

a first curved arm having a first connecting portion formed on a first end thereof, the first connecting portion having a first press portion formed on a distal end of the first connecting portion and a first disassembling portion formed on a second end of the first curved arm, the first disassembling portion having a first semicircle indentation defined therein and a first curved protrusion perpendicularly extending therefrom to define a first semicircle groove that communicates with the first semicircle indentation, a first operating portion formed on an outside wall of the first connecting portion for user to operating the pipe disassembling tool, the first curved arm having a pair of first protrusions laterally extending from the first connecting portion;

a second curved arm pivotally connected with the first curved arm by a pin, the second curved arm having a structure corresponding to that of the first curved arm, the second curved arm having a second connecting portion formed on a first end thereof, the second connecting portion having a second press portion formed on a distal end of the second connecting portion and a second disassembling portion formed on a second end of the second curved arm, the second disassembling portion having a second semicircle indentation defined therein and communicating with the first semicircle indentation to define a through hole when the first curved arm and the second curved arm abut each other, the second disassembling portion including a second curved protrusion perpendicularly extending therefrom to define a second semicircle groove that communicates with the second semicircle indentation, the first semicircle indentation, the first semicircle groove, the second semicircle indentation and the second semicircle groove communicating with one another and defining a cylindrical passage when the first circle arm and the second curved arm abut each other, a second operating portion formed on an outside wall of the second connecting portion for user to operating the pipe disassembling tool, the first operating portion, the second operating portion and the pin linearly corresponding to one another, the second curved arm having a pair of second protrusions laterally extending from the second connecting portion, the pair of first protrusions and the pair of second protrusions overlapped and the pin extending through the pair of first protrusions and the pair of second protrusions; and

a torsion spring sleeved on the pin and located between the pair of first protrusions and pair of second protrusions, the torsion spring having two opposite ends respectively abutting against an inside wall of each of the first press portion and the second press portion to make the first curved arm and the second curved arm abut each other when the pipe disassembling tool us in an original condition.

3. The pipe disassembling tool as claimed in claim 1, wherein the first operating portion and the second operating portion are a recess for use to force when operating the pipe disassembling tool.
