Abstract
The invention provides a multi-purpose safety device which can be used in conventional nailing operations to guide the nail to be driven safely, conveniently and quickly at a desired angle and which can be used for measuring angles and inclinations as well as levelling. The invention includes a driving member disposed in a sleeve which in turn mounted on an upper side of a housing, a nail advancing plate at one side of the housing for advancing nails, and a nail guiding body below the sleeve for guiding and positioning a nail beneath the driving member whereby the nail can be driven into an object by the driving member. An angle meter is further mounted in the housing for measuring angles as well as indicating a desired angle by which the nail has to be driven.
