Abstract:
Slip-joint pliers have a pair of plier members each having a jaw portion and a handle portion, a pivotal bolt, a nut, and a spring member. The spring member is arcuate and has long and short downward projections. One of the plier members has a bolt whole and an annular groove including a through hole for accommodating the spring member therein. The other plier member has a bolt hole defined by first and second slip changeover holes communicating with each other and an engaging recess contiguously communicating with the first slip changeover hole. The short downward projection of the spring member abuts the wall surface of the through hole and the long downward projection contacts the wall surface of either the first slip changeover hole or the engaging recess to automatically bias open the jaw portions of the pair of plier members.
