Indexing plunger

摘要

An indexing plunger is provided whereby a first downward force exerted on a hand grip or a lever will move a pin assembly downwardly and whereby a second rotating force exerted on the hand grip or the lever either clockwise or counterclockwise will lock the device into place by extending the locating pin and thereby locking it into place using the compression force exerted by an internal spring. This embodiment can assume a number of different physical configurations. In another preferred embodiment, the object is to provide an indexing plunger that moves the locating pin incrementally downwardly through the housing when the handgrip is rotated in the clockwise direction. At all times during the pin's downward movement, a compression spring maintains an opposing force on the handgrip.
