The present invention relates to a hand tool, and more particularly to a pair of pliers capable of wire stripping.
A pair of pliers is a hand tool widely applied to cut cables and to pinch or bend objects. A specialized pair of pliers is even designed for stripping an electrical insulation off a cable.
A conventional pair of pliers has two levers. The two levers are pivotally connected to each other via a shaft. Each one of the two levers has a handle portion and a jaw portion. The jaw portion has a cutting blade and multiple stripping notches. The two cutting blades of the two jaw portions of the two levers are capable of cutting the cable. The multiple stripping notches of the two jaw portions are capable of stripping an electrical insulation of the cable.
However, the conventional pair of pliers may fail to cut the electrical insulation of the cable due to the effort applied to the two handle portions of the two levers is small. The conventional pair of pliers may also damage or cut off a metal wire inside the electrical insulation of the cable when the effort applied to the two handle portions of the two levers is intense.
There are also other pairs of pliers for stripping electrical insulation of wires. However, these pairs of pliers are specialized to strip electrical insulation of wires and cannot be applied to cut wires. A user has to carry two pairs of pliers respectively for cutting wires and for stripping insulation of wires. The conventional pairs of pliers are inconvenient in aspect of portability.
To overcome the shortcomings of the conventional pair of pliers, the present invention provides a pair of pliers with a wire stripping mechanism to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a pair of pliers with a wire stripping mechanism that is capable of wire stripping.
The pair of pliers comprises a main body with a first lever and a second lever pivotally connected to the first lever and a wire stripping mechanism. The wire stripping mechanism is mounted to the main body and has two stripping assemblies and an elastic unit. Each one of the two stripping assemblies has a clamping mount, a pinching component, a pivoting pole, and a linkage set. The clamping mount is pivotally connected to the main body. The pinching component is pivotally connected to the clamping mount via the pivoting pole. The linkage set has a linkage unit pivotally connected to the pinching component and one of the first lever and the second lever. The elastic unit is connected to the two pivoting poles of the two stripping assemblies. The two stripping assemblies are driven by the first lever and the second lever.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The pair of pliers may be slip joint pliers, needle-nose pliers, locking pliers, or other different pliers. With reference to
