Brown's quick-change tool

摘要

American company Brown Machine has patented its quick-change tooling concept.The bayonet shaped tool allows rapid installation and removal of plug assists without the need for hand tools.The standard changeover method of plug assist involves the use of a wrench to install each plug assist onto a threaded stud.However,using Brown's tool,which is twisted to the locked position,the plug assist is firmly held so that it cannot accidentally rotate to an unlocked position.
