Abstract
The present invention 10 discloses a spring system 20 and a latch system 18 for either maintaining a set of pliers in an open position or a closed position. The spring system 20 operates by having a spring 32 disposed on a pair of studs 42 located in the trough 44 of an outwardly curved portion 40 of the handles 28, 30 of the pliers. The latch system 18 comprises a pair of tongue-like members 48, 50 and a wire loop member 58 which hooks onto a notch 49 in one of the tongue-like members 50. The spring system 20 normally maintains the pliers in an open position when no load is applied to handles 28, 30.
