Multipurpose pliers

A multipurpose pliers for wire stripping, wire cutting and terminal crimping comprising:

• a handle assembly including a fixed handle, a moveable handle, a linkage connected between said handles, a brake block mounted on said linkage and a rachet mounted on said fixed handle coacting with said brake block so that by pressing the moveable handle the brake block permits the linkage to pivot the moveable handle away from said fixed handle;
• a stripping device on said fixed handle, including a stripping vise, an adjusting block and adjusting cams, which are connected so that said handle assembly opens and closes the stripping vise by pivoting of said moveable handle, said vise holding two knives of different heights in a position such that they strip the wire;
• a cutting and crimping device composed of an upper jaw, a lower jaw, a crimping block mounted between said jaws, said crimping block having teeth, said jaws being connected to said handle assembly so that movement of the moveable and fixed handles of the handle assembly drives the upper jaw and the lower jaw to make a corresponding movement such that the jaws cut wire and the teeth of the crimping block crimp terminals onto wire;
• and
• a wrench device mounted on said fixed handle including an adjusting knob and a screw rod shaped and connected to a vise block so that a gap between the said fixed handle and the vise block is set by rotating the screw rod using the adjusting knob.
