摘要：
1. A tool comprising:
a body (10) comprising a pair of flexible leaves (12, 14) joined at their forward ends by a bridge (16) having an elongate aperture (22) therein, said leaves also being joined face-to face at their rearward ends, and being normally bowed outward from one another; and
an elongated collet (40) having a rearward end affixed to the rearward ends of said leaves, and a bifurcated forward end comprising a pair of resiliently flexible tines (44, 46), each tine having thereon a jaw (48) protruding through said aperture, each jaw including an inwardly facing working surface (50) and an outwardly facing oblique cam surface (52) in a position to engage a side of said aperture, so that relative longitudinal movement between the bridge and the jaws, produced by squeezing the leaves together, causes interaction between the sides of the aperture and the cam surfaces to drive the jaws together
is improved by providing that:
the tines of the collet lie in a common plane perpendicular to and bisecting both of said leaves, the length of the aperture being aligned with said plane; and
the two opposed leaves and the bridge are within a blank of sheet material, the aperture being formed within the sheet.
