Disclosed is a wrench, comprising a jaw locking mechanism (10) in the form of an ejector pin, being used to limit a sliding connection component (23, 241, 242) to move relative to a body (2) in a direction toward or away from a fixed jaw (4), and further comprising a handle locking mechanism which is used to limit or allow the rotation of a handle (3) relative to the body (2). By means of the wrench, continuous and multiple rotation of a workpiece is achieved.
