1. An adjustable clamp comprising:
a first handle;
a first jaw extending from the first handle and ending in a first nose tip opposite from the first handle, the first jaw comprising an inner portion that is housed within an outer portion in a manner to allow relative movement between the inner portion and the outer portion to move the first jaw between a retracted position and an extended position to decrease and increase a longitudinal length of the first jaw;
a second handle;
a second jaw extending from the second handle and ending in a second nose tip opposite from the second handle, the first jaw comprising an inner portion that is housed within an outer portion in a manner to allow relative movement between the inner portion and the outer portion to move the second jaw between a retracted position and an extended position to decrease and increase a longitudinal length of the second jaw;
wherein the first jaw is arcuate and has a longitudinally concave surface that faces in a direction toward the second jaw and the second jaw is arcuate and has a longitudinally concave surface that faces in a direction toward the first jaw, the longitudinally concave surfaces creating an opening between the first and second jaws;
the first and second handles being pivotally joined together so that movement of the first and second handles in a direction towards each other moves the first and second jaws in an opposite direction away from each other;
a spring associated with the first and second handles that exerts a biasing force to move the first and second handles in a direction away from each other and cause the first and second nose tips to apply a clamping force; and
a lock in each of the first jaw and the second jaw, wherein the lock in the first jaw comprises a spring-biased detent carried by the inner portion of the first jaw and an opening positioned in the outer portion of the first jaw at a location to receive the spring-biased detent and prevent relative movement between the inner and outer portions when the first jaw is in the extended position and wherein the lock in the second jaw comprises a spring-biased detent carried by the inner portion of the second jaw and an opening positioned in the outer portion of the second jaw at a location to receive the spring-biased detent and prevent relative movement between the inner and outer portions when the second jaw is in the extended position.
