In a single hand-actuated pick-up tool of the type comprising an elongated shaft terminating at spaced-apart upper and lower ends, a pair of spaced-apart, pick-up fingers extending from the lower end of the shaft including a pair of springs for biasing them apart, and a pair of ribbons including a handle with a finger-actuable trigger at the upper end, biased apart from the handle, for drawing the fingers together as the trigger is squeezed against the handle, the improvement of providing for the fingers to be able to close together and form locked configurations less than the fully-opened configuration including an arm extending from the trigger for reciprocal motion as a function of movement of the trigger, at least one notch formed in the arm adapted for engagement with a stop in the handle, a spring urging the arm into sliding contact with the stop as the trigger is moved and, a lever pivotally mounted at the upper shaft end for movement between a first unlocked position that permits the spring to retain the arm in contact with the stop and a second, unlock position where the arm is moved out of contact with the stop to permit full range of motion of the fingers from full open to full closed.

In a single-hand actuated pick-up tool of the type comprising an elongated shaft terminating at spaced-apart upper and lower ends, a pair of spaced-apart, pick-up fingers extending from said lower end of said shaft including first means for biasing said fingers apart to a first, fully-opened position, and second means, including a handle with a finger-actuable trigger at said upper end, said trigger biased apart from said handle, for drawing said fingers together to a second, fully-closed position, as said trigger is squeezed against said handle, the improvement comprising: (a) an arm extending from said trigger adapted for reciprocal motion as a function of movement of said trigger; (b) at least one notch formed in said arm adapted for engagement with a stop in said handle; (c) bias means urging said arm into sliding contact with said stop as said trigger is moved; and, (d) a lever pivotally mounted for movement between a first position, that permits said bias means to retain said arm in contact with said stop, for positioning said fingers in fixed configurations less than said first, fully-opened position, and a second position, that overcomes said bias means and moves said arm to a position spaced-apart from said stop to allow free, unhampered movement of said fingers from said first, fully-opened position to said second, fully-closed position as a function of said finger-actuable trigger.
