摘要

The hand tool resembling pliers is used to join two sheets or strips of material together. One jaw (2) of the pliers has a screw with a plain end (5) which projects beyond the face of the jaw. The other jaw (3) has a spring loaded pin (6) which also projects above the face of the jaw. A strip or sheet of material (11) has a hole (12) fitted over the end of the pin. A second strip or sheet (10) is placed between the jaws which are then closed. The end of the screw deforms the material of the strip or sheet forcing it into the hole as the pin is forced downwards. The button formed by the deformation of the strip is wedged in the hole holds the two strips together.
