ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a plier tool or a shear tool, and more particularly to a plier tool or a shear tool having one or more tool members that may be easily attached onto and disengaged from the tool body and that may be easily replaced with the other tool members.
2. Description of the Prior Art
U.S. Pat. No. 4,793,224 to Huang, and U.S. Pat. No. 5,826,467 to Huang disclose two typical ring plier tools having a tool member, in which the driving directions of the tool member may be changed by securing different portions of the tool member onto the tool body. However, the other plier tool members or shear members may not be changed or attached onto the tool body, and may not be replaced with each other. In addition, the tool member and the tool body are pivotally or rotatably coupled together with a shaft that may be damaged after use.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional plier tools or shear tools.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a plier tool or a shear tool including one or more tool members that may be easily attached onto and disengaged from the tool body and that may be easily replaced with the other tool members.
In accordance with one aspect of the invention, there is provided a tool comprising a tool body including a pair of handles having a first end rotatably secured together with a tube, the handles each including a pole provided thereon, and one or more tool members each including a pair of levers having an orifice formed in a middle portion of the levers for receiving the tube, the levers of the tool member each including a first end having a tool element provided thereon and each including a second end having an aperture formed therein for receiving the poles of the tool body respectively. The tool elements of the tool member may be moved toward and away from each other by the handles. The poles and the tube of the tool body may be easily and quickly engaged into the apertures and the orifice of the levers for easily and quickly securing or disengaging either of the tool members from the tool body.
The tool member includes a hub disposed in the middle portions of the levers and having the orifice formed in the hub for receiving the tube. A securing device is further provided for securing the hub of the tool member to the tube of the tool body and includes a hole formed in the tube, a ball received in the hole of the tube, and a forcing device for forcing the ball to engage with the hub of the tool member and to secure the hub to the tube.
The hub includes a recess formed therein for receiving the ball. The forcing device includes a shaft received in the tube, the shaft includes a depression formed therein for receiving the ball, and the forcing device further includes a device for disengaging the depression of the shaft from the ball.
The disengaging device includes a spring engaged with the shaft for biasing the shaft relative to the tube and to disengage the depression of the shaft from the ball. The tube includes a chamber formed therein for receiving the spring, the shaft includes a head slidably received in the chamber of the tube and engaged with the spring.
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.
