Locking pliers having both fast and fine adjustment to jaw spacing

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;
• 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.
