A D-type connector unplugging tool comprising two metal arms, a plurality of positioning grooves, a handle, two U-shaped end sections and a push-pin assembly. The metal arms have a front end and a back end. The metal arms are coupled together at a back end and formed a clamp opening at a front end. The positioning grooves are located at corresponding positions on the metal arms between the front end and the back end. The handle is fixed onto the back end of the metal arms. The two U-shaped end sections are extensions secured to the front end of the two metal arms and each having a notch at its tip. The push-pin assembly further includes a main body having two ends locally fastened to the metal arms such that the whole push-pin assembly can slide along the two metal arms between the front end and the back end; also, there is a circular tube fixed to the main body and inside the tube there is a spring having two steel balls placed at each end. As the push-pin assembly slide along the metal arms, the compressed spring pushes the steel balls against the arms till lodging into one pair of positioning grooves, thereby freezing the clamp opening. Therefore, by sliding the push-pin assembly to a proper position along the metal arms, the appropriate clamp opening can be obtained.
