An exterior cover for attachment to the exterior surface of a hinged computing device's base may modify the size, position, and/or footprint of one or more extensions, or feet, projecting from the bottom of the base. The modification may serve to increase the stability of the hinged computing device when the hinged computing device is in an open position (i.e., when the display element is separated from the base).

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.
