摘要: A spiral ratchet screwdriver has a main body (1 supporting a slidable and rotatable'shank (3), and containing a latch pawl (19) which is pivotable by a cam mechanism (7, 11, 12). The latch pawl, when turned inwardly of the main body, locks the shank against sliding movement. The cam mechanism is normally locked by a rod (15) to prevent it from moving the latch pawl (19) to the locking position of the pawl, but is automatically unlocked when the shank is fully retracted into the body.
