ABSTRACT:
An improved tool head for releasably retaining a blade includes a body and a clamping member pivotally hinged together for relative movement therebetween by rotation of a threaded operating member. The operating member is rotatable to axially move the same into threaded engagement with the body and clamping member and, at a final point in its axial translation, contacts a camming structure on the clamping member. Engagement of the operating member with the camming structure applies a laterally directed force to the clamping member, pivoting the same about its hinged connection to the body and carrying a pair of blade receiving lips on the body and clamping member into relative blade-retaining proximity to firmly secure a blade between the lips.
