Abstract
An apparatus that retracts a plunger along an axis about which a handle pivots. The handle has two ends that are perpendicular, the second end having a sidewall with a barrel forming a chamber in which the plunger is slidably mounted. The sidewall has elongated slots through which opposing roller bars that extend from the plunger protrude through. A collar body is rotatably mounted to the second end and has opposing openings with triangular surfaces. The roller bars rest on the triangular surfaces, and when the first end of the handle is rotated about the central axis, the slot sidewalls drive the roller bars around the triangular surfaces, thereby causing axial movement of the plunger away toward the first end of the handle without moving the first end to move out of the plane in which it rotates.
