Over the years I have been on many construction sites and have noticed a constan t problem throughout all of these sites. That is, the problem of maintaining a pro per connection between power supply and power tool. Since power sources on job sites is limited, extension cords are utilized to connect power tools and equipment. This connection has proven to be unreliable due to mishaps from continuous strain on lines, causing power interruptions during some often precarious situations. This in tur n will often lead to user anxiety and time consumption. It is the intent of this application to ascertain a patent on a mechanical union device used to alleviate this problem and also contribute to construction site safety and ea se of storage.
