Abstract: A strap with retrieving components includes an elongated strip of flexible material having a central portion extending along a longitudinal axis there through. The retrieving components are secured at opposite ends of the central portion of flexible material and comprise first and second rigid, hook shaped components, each secured at opposite ends of the central portion of flexible material so that the first and second hooked shaped components are disposed in a plane through the central portion of the strip of flexible material. Each of the first and second hook shaped components are curved in opposite directions from the longitudinal axis so that a free end of the first hooked shaped component extends in an opposite direction from a free end of the second hooked shaped component.

Abstract: The present invention relates to a hook device which can be firmly positioned on a nailer, wherein a fastener is used to insert in the rear plug by cooperating with a ring-like hook, so as to make the rear plug slightly bulge out to press against the ring-like hook, thus, the ring-like hook is firmly fixed to the rear plug. The hook device can be arbitrarily and rotatably positioned on the nailer, wherein a plurality of positioning grooves are formed on the step circular wall of the rear plug, and a ring-like hook is mounted on the rear plug. The ring-like hook is provided with a positioning unit which is to be engaged in the positioning grooves of the rear plug, so as to enable the ring-like hook to be rotatably positioned on rear plug. Thereby, the user can position the nailer arbitrarily according to real needs.
