ABSTRACT:
A pair of pliers for loading-unloading E-type clamping piece mainly comprises a clamping operational strip in shape of a long flat board, wherein a C-opening is formed at one end and a crotched opening at the other; and a handgrip that can be inserted with those two ends of the clamping operational strip alternatively. The handgrip is further provided with a movable pin, which can move up or down, fastening to the clamping operational strip. By virtue of abovesaid construction, the clamping operational strip can hold an E-type clamping piece to clamp at a circular groove on a target article, or vice versa. The C-opening can be used by the way to select a required E-type clamping piece by comparing its opening width with outer diameter of the circular groove on a target article.
