Technical Examples
The invention is an adjustable wrench comprising a handle with a terminal end and grip end, the terminal end defining a lower bolt claw. A jackscrew is slidably coupled to the handle, the jackscrew being movable to control the movement of the upper and central bolt claws. The upper, central, and lower bolt claws are fitted to the shape of a standard hexagonal bolt head, being adjustable to different sized bolts upon terminal or distal movement of the jackscrew relative to the handle. The central bolt claw is fitted through a slot in the upper bolt claw which defines an inclined ramp surface such that movement of one claw is coupled to movement of the other claw. The claws move cooperatively in reaction to the stationary, lower bolt claw to form a tightly fitted surface for a bolt head.
