The instrument includes a longitudinally reciprocal spring biased member having a resilient body contact element on the end thereof and a manually movable handle connected thereto for compressing the resilient spring with adjustable means being provided for releasing the spring and contact after a predetermined compression of the spring, thereby enabling a controlled force of adjustment to be applied at a rapid speed and in a precise line of drive.
