Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of Invention 
         [0002]    The invention relates to wire and cable stripper and more particularly to a wire and cable stripper that cuts the insulation layer off from a wire or a cable. 
         [0003]    2. Description of Related Art 
         [0004]    Wire and cable stripper is a common tool that cuts off an insulation layer of a wire or cable. Moreover, a common way to make a direct cut to the insulation layer is by using a knife or a pair of needle nose pliers in addition to a pair of sharp-nose pliers. 
         [0005]    However, the methods are both challenging techniques to a user and can cause breakage or over-bending to a wire if the technique is not used correctly. 
         [0006]    Therefore, there is a need in the market for improving the functionality deficiency and causes the development of many different types of wire and cable stripper. 
         [0007]    However, the methods of achieving the cut is typically by clamping the cable or wire tightly onto the wire and cable stripper, then by either rotating the wire and cable stripper, the cable, or wire itself, and then making the cut on the insulation layer of the wire or cable by utilizing a cutting piece mounted on the wire and cable stripper. 
         [0008]    There have been a number of prior wire and cable stripper patents, for example, Taiwan Patent Numbers M354267, M452271, and M582656, and U.S. Pat. Nos. 4,955,137 and 4,945,788. Despite prior patents reveal the functionality of cutting the insulation layer of a wire or cable, there are still many shortcomings. For example, the size of the wire and cable stripper is large and complicated assembly process that involves numerous components and parts. 
         [0009]    Therefore, not only the prior wire and cable stripper is inconvenient to carry, but also is very complicated to manufacture and not suitable for mass production. 
         [0010]    The inventor of the invention, having many years of extensive development and manufacturing expertise in the related field, takes these shortcomings into consideration and thinks through the details, and has finally developed a simple structure for a novel wire and cable stripper. 
       SUMMARY OF THE INVENTION 
       [0011]    The objective of the invention is to offer a wire and cable stripper which cuts the insulation layer off from a wire or a cable. Furthermore, the construction of the wire and cable stripper is convenience to carry around. 
         [0012]    The invention is accomplished through the following technical programs: 
         [0013]    A wire and cable stripper for cutting off an insulation layer of a cable or a wire, the wire and cable stripper comprising: a first clamp handle part having a front of the first clamp handle part and a rear of the first clamp handle part; a slot disposed at the rear of the first clamp handle part; a second clamp handle part having a front of the second clamp handle part and a rear of the second clamp handle part wherein the front of the second clamp handle part has a cavity, the rear of the second clamp handle part has a movable part of the slot of the corresponding rear of the first clamp handle part, the movable part of the rear of the second clamp handle part and the slot of the rear of the first clamp handle part push against each other, and the first clamp handle part and the second clamp handle part are connected together through a deformable connecting piece; the first clamp handle part and the second clamp handle part are connected through only one deformable connecting piece; the first clamp handle part and the second clamp handle part are connected by the deformable connecting piece to form integrally as a single body; and a cutting piece disposed inside the cavity wherein a portion of the cutting piece protrudes out of a surface of the cavity of the front of the second clamp handle part. 
         [0014]    When applying external forces to the rear of the first clamp handle part and the rear of the second clamp handle part, the movable part of the rear of the second clamp handle part will start to displace along the slot of the rear of the first clamp handle part, stress the connecting piece and cause it to deform, the front of the first clamp handle part and the front of the second clamp handle part will displace reversely from each other, and a wire or cable will placed in the cavity. The connecting piece tends to restore to its original position automatically when the external forces are removed. Furthermore, the reverse displacement of both the front of the first clamp handle part and the front of the second clamp handle part will also tend to disappear. This movement causes the front of the first clamp handle part and the front of the second clamp handle part to move closer to one and other and secures the previously placed wire or cable. 
         [0015]    After the wire or cable is secured, followed by rotating the wire and cable stripper, the cutting piece will make a cut on the insulation layer of the wire or cable; or by fixating the wire and cable stripper, followed by rotating the wire or cable to allow the cutting piece to make a cut on the insulation layer of the wire or cable.
