Interchangeable-socket dropproof wrench comprises three essential parts: handle assembly, socket assembly, and pip-pin assembly. Socket assembly is disengaged from handle assembly only when engaged to pip-pin assembly. Socket assembly therefore remains tethered and cannot be dropped or lost except by deliberate removal of pip-pin. Dropproof tool is useful where ever loss of component would be inconvenient or hazardous. Used by divers and by people working on scaffolds. Mechanism is easily operated by Technicians wearing thick gloves, space suits, diving suits, or other protective attire.
