Ratchet wrench with pivotable head

摘要

A power ratchet wrench has a handle for gripping and holding the wrench and a head pivotally connected to the handle for pivoting movement relative to the handle about a pivot axis. A locking mechanism comprising a pivot assembly pivotally connects the head to the handle. The locking mechanism is configured to permit selective angular positioning of the head relative to the handle on the pivot axis and is operable between an adjusting mode in which the head is angularly positionable relative to the handle and a locking mode in which the head is locked in an angular orientation relative to the handle. The locking mechanism is rotatable about an axis transverse to the handle between the adjusting mode and locking mode of the locking mechanism.
