Abstract
A nail engaging device of a nailer includes a cover pivotally connected to the barrel of the nailer and two recesses are defined in the cover. A first nail pushing member and a second nail pushing member are respectively received in the two recesses and two springs respectively urge the first nail pushing member and the second nail pushing member. A protrusion retractably extends from one of the two recesses and is located beside the second nail pushing member. The first nail pushing member and the second nail pushing member push the nails connected by wires in a nail feeding mechanism. When using nails connected by a plastic plate, the second nail pushing member is compressed by the second nail pushing member. The protrusion supports the plastic plate and pushes the nails into the barrel.
