    • 专利摘要:
    A two way open-end wrench has a rotatable, captive, split socket (13) which is selectively locked and unlocked to the wrench handle (5) for torque transmittal through the meshing engagement of two opposed sets of teeth (12, 16). ; One set (16) is disposed around the periphery of the i open-sided socket member (13) and the other (12) within the forward, concave end of a spring-loaded coupler (9) disposed partly within and partly outside the wrench body (2). Engagement of the teeth (12, 16) is effected by the inward , movement of the coupler (9) when a user grips the wrench handle (5) preparatory to turning it. Relaxation of the grip at the end of a stroke permits the handle (5) to be returned to the starting position while the socket (13) remains stationary. A projecting extension (21) on the socket (13) provides for manual rotation to the open position, permitting the took to be withdrawn from a fastener on a tubing line, pipe or cable.
