LOW-PROFILE FASTENER RETAINING DEVICE WITH SINGLE-SIDED RETENTION AND RELEASE

摘要

A single-sided fastener retaining device includes a resilient arm and a lever arm joined by a fulcrum. A fork at the end of the lever arm includes first and second arms that extend to either side of and at least to the level of the axis of the driving tool to define an opening facing the axis to receive the shaft of a fastener of various sizes and hold the head of the fastener to the working end of the driving tool in a retained position. The release mechanism is responsive to the application of a force to elastically deform the resilient arm causing the lever arm to pivot on the fulcrum moving the fork away from the axis to a release position to release the fastener.
