ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a wrench, and more particularly to a wrench having a plier device.
2. Description of the Prior Art
Typical wrenches may be used for driving fasteners only and comprise a compact configuration having no spaces or chambers for receiving the other tools, particularly the plier devices. For some working conditions, the workers may require to use both wrenches and plier devices frequently and alternatively to actuate the fasteners. None of the typical tools provide a tool combination having both the wrench and the plier device.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional wrenches and plier devices .
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a wrench and plier device combination including a plier device received in the wrench for allowing the users to easily obtain both or either of the wrench and the plier device.
In accordance with one aspect of the invention, there is provided a wrench and plier device combination comprising a wrench body including a first end having a wrench tool provided therein, and including a second end having a chamber formed therein, a casing rotatably secured to the second end of the wrench body at a pivot pin and rotatable outward of the chamber of the wrench body and rotatable inward and received in the chamber of the wrench body, and a plier device received in the casing and received in the wrench body when the casing is received in the chamber of the wrench body.
The wrench tool includes a fixed jaw provided on the first end of the wrench body and includes a second jaw rotatably secured to the first end of the wrench body at a pivot shaft and rotatable toward the fixed jaw, and means for biasing the second jaw toward the fixed jaw.
The casing includes a side wall and an end wall for forming a space therein and for receiving the plier device. The wrench body includes a pair of plates disposed parallel to each other and having a coupling portion coupled together at a panel for forming the chamber therein, the panel of the wrench body and the side wall and the end wall of the casing together form the space in the casing and the wrench body for receiving the plier device. The panel of the wrench body includes a length shorter than that of the casing for allowing the casing to be rotated outward of the handle portion of the wrench body.
The plier device is a foldable plier device and includes a pair of jaws pivotally secured together at a pivot axle, a pair of hand grips pivotally secured to the jaws respectively at a pivot rod for allowing the hand grips to be rotated and folded relative to the jaws of the plier device. The hand grips of the plier device each includes a cavity formed therein for receiving the jaws of the plier device when the jaws are rotated and folded relative to the hand grips.
