TOOL WITH TWO HANDLES

A tool includes a first member, a second member, a reinforcing device and a fastening assembly. The first member has at least one first working portion and a first pivoting portion. The second member has at least one second working portion and a second pivoting portion. The reinforcing device is arranged between the first member and the second member and configured to abut in surface contact against the first pivoting portion and the second pivoting portion. The fastening assembly inserts through the first pivoting portion, the second pivoting portion and the reinforcing device so that the first pivoting portion and the second pivoting portion are pivotally connected to each other.

BACKGROUND OF THE INVENTION

The present invention relates to a hand-operated tool with two handles and, more particularly, to a hand-operated tool with two handles utilizing the principle of leverage.

Generally, a double-handled hand tool utilizing the principle of leverage is composed of two working arms pivoted to each other. The two working arms are pivotally connected through a pivot acting as a fulcrum, and each working arm has a handle and a working head opposite to the handle, so as the mechanical advantage of a lever can be exploited by placing an object to be worked as close to the fulcrum as possible.

However, the two working arms can be pivoted to each other by only connecting a pivot pin to the two working arms, but when the external force applied to the handle is too large, the two working arms will inevitably sway, resulting in the working head unable to work properly.

Thus, a need exists for a novel tool that mitigates and/or obviates the above drawbacks.

BRIEF SUMMARY OF THE INVENTION

An objective of the present invention is to provide a tool with two handles, which includes a first member, a second member, a reinforcing device, and a fastening assembly. The first member has at least one first working portion and a first pivoting portion. The second member has at least one second working portion and a second pivoting portion. The reinforcing device is arranged between the first member and the second member and is configured to abut in surface contact against the first pivoting portion and the second pivoting portion. The fastening assembly inserts through the first pivoting portion, the second pivoting portion, and the reinforcing device so that the first pivoting portion and the second pivoting portion are pivotally connected to each other.

In an example, the reinforcing device includes a first gasket, a second gasket, and a spacer arranged between the first gasket and the second gasket. The first gasket abuts in surface contact against the first pivoting portion. The second gasket abuts in surface contact against the second pivoting portion. The spacer abuts against the first gasket and the second gasket.

In an example, the first pivoting portion has a first abutting face. The first member further has a first abutting recess adjacent to the first abutting face, and a first containing recess spaced from the first abutting recess. The second pivoting portion has a second abutting face. The second member further has a second abutting recess adjacent to the second abutting face, and a second containing recess spaced from the second abutting recess. The first gasket is arranged in the first abutting recess and the second containing recess and has a first external side face abutting against the first abutting face, a first internal side face opposite to the first external side face, and a first through hole penetrating through the first external side face and the first internal side face. The second gasket is arranged in the second abutting recess and the first containing recess and has a second external side face abutting against the second abutting face, a second internal side face opposite to the second external side face, and a second through hole penetrating through the second external side face and the second internal side face. The spacer has a first end face, a second end face opposite to the first end face, and a third through hole penetrating through the first end face and the second end face. The fastening assembly includes a bolt and a nut threaded connected with the bolt. The bolt inserts through the first pivoting portion, the second pivoting portion, the first through hole, the second through hole, and the third through hole.

In an example, each of the first gasket and the second gasket is formed in a disc shape and has a circular cross sectional shape. The spacer is cylindrical and has a circular cross sectional shape.

In an example, the first gasket, the second gasket and the spacer are made of metal.

In an example, the number of the at least one first working portion of the first member is two. The two first working portions are respectively disposed at two ends of the first member, and the first pivoting portion is disposed between the two first working portions. The first member further has a first gripping portion arranged at an outer side thereof and disposed between one of the two first working portions and the first pivoting portion. The number of the at least one second working portion of the second member is two. The two second working portions are respectively disposed at two ends of the second member, and the second pivoting portion is disposed between the two second working portions. The second member further has a second gripping portion arranged at an outer side thereof and disposed between one of the two second working portions and the second pivoting portion.

In an example, the first member further has at least one first limiting rib disposed at an inner side thereof. The second member further has at least one second limiting rib disposed at an inner side thereof. The at least one first limiting rib and the at least one second limiting rib abut against each other.

In an example, the number of the at least one first limiting rib of the first member is two. The two first limiting ribs are spaced from each other.

The number of the at least one second limiting rib of the second member is two. The two second limiting ribs are spaced from each other. One of the two first limiting ribs is configured to be located between the two second limiting ribs when the first member and the second member pivot to each other.
