Nail removal tool

摘要

A nail removal tool in the form of an adapter for attachment to the drive socket of a rotary driver such as a rotary pneumatic impact driver. The adapter includes a drive shaft engagable with the chuck of the pneumatic driver, a cylindrical bit with a slot for receiving the body of a nail and a ramp for engaging under the head and lifting it to dislodge the nail from its embedded location. Slop between the drive blade and the slot in the cylindrical bit serves as a flexible connection to provide proper presentation of cylindrical bit allowing wedging of the adapter beneath the head of a nail which is reluctant to be removed.
