Abstract
A plunger clamp capable of locking in either a retracted or extended position having a rigid body slidably supporting an elongated plunger. A bifurcated lever is pivotally connected inside the body and to a V shaped link arm, the link arm is pivotally connected to the plunger where the link arm translates the angular motion of the lever to drive the plunger between the retracted and extended positions. Essentially the entire linkage assembly is housed in cavities formed by the body during actuation of the lever.
