Abstract:
1. A pair of locking pliers, comprising a first handle; a second handle; a first jaw and a second jaw at a top end of said first and second handles, respectively; a first spring between said second jaw and said first handle; a lever between said first and second handles, a third handle on said second handle engaging said lever; a seesaw member pivotally joined to a back end of said first handle; and an adjustment member capable of sliding up and down within said first handle; wherein said adjustment member contains an adjustment body and an adjustment bolt axially and rotatably threading through said adjustment body; along a side edge of said adjustment body, a limiting groove is configured where a pin threading through a hole at a back end of said first handle is embedded; said seesaw member contains a seesaw handle and a second spring engaging said seesaw handle; said second spring engages said seesaw handle so that a first chain of teeth along a top end of said seesaw handle engages or disengages a second chain of teeth along a circumference of said adjustment body to lock said adjustment body or to allow said adjustment body to slide up and down; when said adjustment body slides and said lever is pushed upwards or downwards, a spacing between said first and second jaws are adjusted quickly; when said adjustment body is locked by said seesaw handle, said adjustment bolt is twisted so that a top end of said adjustment bolt raises or lowers said lever to fine-tune said spacing.
