Abstract
A pair of punch pliers include a handle, a control shank assembly, a punching member, and a connecting device. The handle has a first end provided with a grip portion, a second end provided with a punching seat and a mediate portion provided with a hollow receiving base. The control shank assembly includes two press members each pivotally mounted on the receiving base of the handle, and a press block mounted between the two press members. Thus, the blanks of the handle are juxtaposed to each other, and the blanks of each of the two press members of the control shank assembly are juxtaposed to each other, so that the wasted materials of the handle and each of the two press members are reduced largely, thereby decreasing the costs of fabrication of the punch pliers.
