The adjustable wrench further comprises a bearing guide device including at least two bearing guides disposed in a space between an outer wall of the gear rack and an inner wall of the mounting slot so that at least one of the bearing guides is arranged on one side of the gear rack and at least one of the bearing guides is arranged on the opposite side of the gear rack.

Abstract: A powered adjustable jaw wrench comprises a wrench body having a handle portion and a head portion defining a stationary jaw, a movable jaw reciprocally mounted to the head portion, a driven mechanism operably connected to the movable jaw, and a drive mechanism mounted to the body member and including a power source and an indexing mechanism. The driven mechanism includes a worm driving the movable jaw and an indexing wheel operably connected to the worm gear. The indexing mechanism is driven by the power source and includes an oscillating pallet member. The pallet member incrementally drives the indexing wheel so as to convert an oscillating movement of the pallet member into an incremental rotatable movement of the indexing wheel.

Abstract: An adjustable wrench comprising a moveable jaw, a stationary jaw, and a worm gear driving the moveable jaw. The worm gear is, in turn, meshed with a rack of the moveable jaw and is driven by a reversible servomotor. Activation of the servomotor produces linear reciprocating motion of the moveable jaw. The adjustable wrench further includes a positioning device provided for limiting a travel of the moveable jaw in at least one direction away from or toward the stationary jaw. Preferably, the positioning device includes a first preset stop for limiting a travel of the moveable jaw in the direction toward the stationary jaw to define an inward limit of travel of the moveable jaw and a second preset stop for limiting a travel of the moveable jaw the directions away from the stationary jaw to define an outward limit of travel of the moveable jaw.

Abstract: A multi-functional tool comprising an extendable power tool handle unit with an interchangeable connect feature able to receive and power various size interchangeable, adaptable adjustable wrench head units and other adaptable tool attachments. The interchangeable wrench head units are easily connected and disconnected to the power tool handle unit. Each interchangeable adjustable wrench head unit has a self-contained transmission connectible to and powered by the adaptive power handle unit. The interchangeable wrench head units comprise of a moveable jaw, a stationary jaw, and a worm gear. The worm gear is meshed with a rack of the moveable jaw and the worm gear is driven by a motor and transmission. Activation of the motor produces linear reciprocating motion of the adjustable jaw. A power source from the handle provides the power to a control switch. The switch controls the function of the adjustable wrench heads and other powered tool attachments.
