A rapid adjustable wrench includes a body, a movable jaw, and an engaging device. The body has a fixed jaw, a sliding groove, and a containing recess. The movable jaw includes a sliding portion movably arranged in the sliding groove and a first toothed portion adjacent to the sliding portion. The engaging device includes an engaging member and a toggle switch. The engaging member is arranged in the containing recess and has a second toothed portion selectively engaged with the first toothed portion. One end of the toggle switch is connected to the engaging member. The toggle switch is able to drive the engaging member to move between an engaging position and a releasing position.

A tool (10) for rotating a screw-on oil filter cartridge, the tool comprising a driving member (28, 28b); gripping jaws (12a, 12b) movable in relation to each other for gripping an oil filter cartridge; a guide arrangement (13, 14a, 14b) for guiding the gripping jaws; means (16a, 16b) for biasing the gripping jaws towards each other; and a driving mechanism (28, 28c, 24, 22a, 22b, 20a, 20b, 21a, 21b) coupled to the driving (28b) member and gripping jaws (12a, 12b) for converting rotation into movement of the gripping jaws towards each other, into engagement with an oil filter cartridge and applying either screwing or unscrewing torque thereto. The tool comprises: a locking mechanism (30, 32, 28, 24) for releasably locking the gripping jaws (12a, 12b) at a pre-determined distance from each other; and a release actuator (28a) for unlocking the locking mechanism and releasing of the gripping jaws.
