Abstract
A wrench includes a fixed jaw formed on one end of a handle, a pivotal jaw pivotally secured to the handle and having one end for engaging with a fastener. The pivotal jaw has a middle cavity for receiving a spring-biased engaging member which may engage with the handle to force the pivotal jaw toward the fixed jaw. The fixed and the pivotal jaws each includes a flat engaging surface and a notch for alternatively engaging with the opposite flat surfaces and the opposite corners of the fastener and for allowing the handle to be rotated for only thirty degrees relative to the fastener.
