Abstract

A mounting apparatus including a first element is slideably connected to a second element by a joint. The joint includes first and second spaced apart walls on the first element and a third wall on the second element that is slideably disposed between the first and second walls. A biasing feature, such as a spring, is disposed between the first and second elements. Preferably, a restraining feature is used for restraining slidable movement to one degree of freedom of motion between the elements. A bore is disposed in one wall of one of the elements and is generally alignable with a conical cavity in another wall of another of the elements and a rod disposed through the bore. The rod has a conical tip with a tip conical surface for engaging a cavity conical surface of the conical cavity. The conical tip is smaller than the conical cavity in diameter so as to being able to effect the biasing movement by axial movement of the rod in the bore. The restraining feature further may include a pivoting feature for restraining slidable movement between the elements to pivoting about a pivot point of the pivoting feature and in another embodiment a linear restraining feature may be used for restraining slidable movement between the elements to linear movement. The holder may be used to hold an electrode.
