Patent ID: 7188556

Claim:
A rotatable hand tool for controlling torque applied at a rotation axis, comprising: a handle for rotation about said axis, a bit connected to said handle and said bit aligned along said axis and presenting a reception space therebetween and being relatively movable toward and away from each other along said axis, a torque-transmitting insert in said reception space and interconnecting said handle and said bit rotationally together through said insert when said handle and said bit are positioned toward each other along said axis, and a member connected between said handle and said bit for releasably restraining said relative movement of said handle and said bit away from each other along said axis and thereby retain said insert in said reception space; said member being rotationally telescoped over said handle and said bit and having a pin and groove connection between said member and said handle whereby movement of said member provides relative movement between said pin and said groove for the release and restraint of relative movement of said handle and said bit.
