1. Field of the Invention
The present invention relates to a plier device, and more particularly to a plier device having two tool members that may be changed with each other.
2. Description of the Prior Art
A typical plier device is disclosed in U.S. Pat. No. 5,245,721 to Lowe et al. and comprises a pair of jaw elements pivotally coupled to the handles and each including two ends each having a tool member provided thereon. The tool members may not be easily and quickly replaced or changed with each other.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional plier devices.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a plier device including a pair of tool members that may be easily and quickly and changeably secured to the handles.
In accordance with one aspect of the invention, there is provided a plier device comprising a pair of handles each including a first end having a channel formed therein and opened relative to the handles respectively and facing toward each other, and a tool device including a pair of rods, the rods including a middle portion pivotally secured together at a pivot pin for allowing the rods to be rotated about the pivot pin and including two ends each having a pair of jaws formed and provided therein, the jaws each including a rib formed thereon and engaged into the channels of the handles respectively for detachably securing the tool device to the handles.
The handles each includes a pair of flanges extended inward of the channel respectively, the jaws each includes a pair of opposite grooves formed therein for defining the rib and for receiving the flanges of the handles respectively.
A securing device is further provided for detachably securing the jaws to the handles respectively and includes a pair of spring-biased projections disposed in the handles respectively and engaged with the jaws for detachably securing the jaws to the handles respectively. The jaws of the tool device each includes a recess formed therein for receiving the spring-biased projections and for securing the jaws to the handles.
The first ends of the handles each includes a block provided therein and having the channels formed therein respectively.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
