Disclosed is an improved probe housing mechanism that will allow for the quick release of a probe tip from a testing tool. The invention includes a probe housing, a double cantilevered beam for holding a probe tip, and a releasable spring mechanism for holding the beam into place. The spring mechanism can be released by squeezing the spring together or by releasing a non-removable locking screw, thereby allowing the beam to be slidably removed from the probe housing for easy replacement.
