发明名称 Debris collection device for use with electrical and hand tools
摘要 The present invention is directed to a debris collection device in which the debris collection device not only contains the debris to avoid injury to the tool user through debris falling into the user's eye, flying debris causing physical injury to the user's body, or particles causing lung injury through being inhaled by the user, but also retains the debris for easy recycling or disposal. The collection portion of this invention is adjustable with respect to its distance from the tool, allowing it to be used to effectively contain debris under a wide variety of conditions.
