do you mean that the springs don't stay attached to the claw or that the claw has pulled out and won't stay in?

if the springs won't stay attached to the claw then you probably don't have enough tension on them. add more tension (this may negate the ability to tune really low)

if the claw won't stay in then you'll need longer screws. this happens often with basswood guitars that are readjusted constantly or the user pulls up on the trem adding tot the tension and weakens the screw slots.
