ABSTRACT:
A hand held, spring actuated single stroke piston desoldering instrument having a removable, replaceable nozzle tip in combination with a novel removal tool which also serves as a holder for several spare tips is disclosed. The barrel of the desoldering instrument is one-piece molded and includes an end cap portion with a forwardly protruding nose portion having a nozzle retaining central bore therethrough. The novel replaceable nozzle element has two annular grooves formed about its periphery: the first mates with an annular reduced diameter shoulder within the retaining bore of the end cap; the second is normally disposed forwardly of an outside of the end cap where it may be gripped by a pair of flexible jaws on the removal tool. A pair of fins on th sides of the nose portion of the end cap engage a cam on the ends of the jaws in a manner such that upon squeezing the jaws together to grip the nozzle while axially rotating the desoldering tool with respect to the removal tool, the nozzle is forecfully pulled from the nose of the desoldering tool.
