ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates generally to a cutting implement, and more particularly to a pair of shears for cutting the water pipe and the like.
DESCRIPTION OF RELATED ART
The conventional water pipe shears are handy tools for cutting the water pipe of a rigid plastic material; nevertheless they lack certain features enabling the shears to be used with ease.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a pair of shears, which can be used with ease to cut the water pipe.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by the water pipe shears comprising a primary handle, a secondary handle, a movable jaw, a connection rod, and a push claw. The push claw is actuated by the secondary handle to push the movable jaw to move toward a fixed jaw, thereby resulting in severance of a pipe which is placed between the movable jaw and the fixed jaw.
The foregoing objective, features, functions, and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
