ABSTRACT:
The adjustable socket comprises a plurality of fingers pivoted by one end thereof to a socket body and enclosed within a partially rotatable shell covering the socket body. A spiral slot in the shell is engaged by a pin or the like extending from the body so that when the shell is partially rotated, the shell extends or retracts axially relative to the body portion thus opening or closing the distal ends of the fingers due to the engagement of the outer surfaces of the distal ends of the fingers with the curved inturned end of the shell. This shell and fingers can be detachably locked in the desired position. This enables the fingers to adjust in order to grasp or grip a nut or bolt within the size range governed by design parameters. A spring reacts between the shell and the body portion normally retracting the shell so that the fingers are in the widest position. A handle assembly is secured to the inner end of the body and may be connected to the body by means of a clutch assembly connected when the handle assembly is pushed downwardly towards the body portion against spring pressure. Alternatively, the clutch assembly may be detachably locked in engagement between the handle component and the body portion.
