Document Type and Number:
WIPO Patent Application WO/2012/018874
Kind Code:
A3
Abstract:
A wrench (10) for applying a drive torque at a drive element includes an elongated handle (14), a clamping element or head (12) having a torque-applying gripping surface, and at least one trigger (20, 21). The head is adjustably or movably mounted at the handle and is adjustable or movable to impart a clamping force at a drive element (16) received at the gripping surface of the head. The trigger is configured to adjust or move the head relative to the handle to impart the clamping force at the drive element. Responsive to a user actuating the trigger, the trigger adjusts or moves the head relative to the handle to impart the clamping force at the drive element irrespective of any movement of the handle relative to the drive element.
