    • An adjustable wrench includes a fixed jaw and a movable jaw movable along a slot in the head. A passage is defined through the head and communicates with the slot. Two rack portions are defined in the guide rod. Two pawls are movably engaged with the passage and each pawl has teeth and the two pawls are alternatively engaged with the two rack portions. Two respective positioning units are located between the two pawls and an inside of the passage so as to position the pawls to be engaged with the pawls or separated from the pawls. The two rack portions are made by Metric system and English system respectively.
    • 可调节的扳手包括可沿着头部中的槽移动的固定夹爪和可动夹爪。 通过头部定义通道并与槽连通。 在导杆中限定两个齿条部分。 两个爪与通道可移动地接合,并且每个棘爪具有齿,并且两个棘爪与两个齿条部交替地接合。 两个相应的定位单元位于两个棘爪和通道内部之间,以便将棘爪定位成与棘爪接合或与棘爪分离。 两个机架部分分别由公制和英制制成。
