ABSTRACT:
An elongated shank is provided having a first handle end and a second hook end including a rigid, reversely turned and inclined hook defining terminal end projecting outward to one side of the shank and toward the first end thereof. The handle includes mounting structure thereon intermediate the handle and hook defining a guide passage closely spaced outward of and paralleling the aforementioned one side of the shank and through which an elongated pull member is lengthwise reciprocated. A first end of the pull member corresponding to the first handle end includes a finger-engageable portion for manually engaging the pull member and lengthwise displacing the latter in a first direction away from the hook and the second end of the pull member includes a laterally outwardly inclined end member thereon projecting outwardly from the side of the pull member remote from the shank and oppositely inclined relative to and toward the hook. The terminal ends of the end member and hook are engageable with each other to limit shifting of the pull member in the second direction toward the hook and spring structure is operatively connected between the pull member and the shank yieldingly biasing the pull member in the second direction. The abutting free terminal ends of the end member and hook define an included angle of generally 90.degree. opening toward the shank and substantially bisected by a plane disposed normal to the shank.
