A rotary tool is disclosed. The rotary tool can include a first arm and a second arm pivotally coupled to one another at a joint. Ends of the first and second arms are positionable at a variable distance from one another by pivoting the first and second arms at the joint. The rotary tool can also include a first rotatable driver disposed at the end of the first arm, a second rotatable driver disposed at the end of the second arm, and a third rotatable driver disposed at the joint. In addition, the rotary tool can include a drive train operably coupled to the first, second, and third rotatable drivers to transfer torque, such that an input torque applied to one of the first, second, and third rotatable drivers causes torque output at the other rotatable drivers.

A multiplier device is presented for use with a handheld drive device for rotating an output shaft and mating driven member. The multiplier device has a rotational shaft with a first end for mating with the driven member and a second end defining a first slide tip. A first gear is mounted to the rotational shaft, a fixed ring gear presents a toothed inner ring, planetary gears are positioned to contact the inner ring and the first gear. The device releasably mates with the handheld drive device and has a second slide tip for cooperation with the first slide tip.

Methods and systems for increasing the efficiency of a remote wrench. The remote wrench can include a flexible plate within the tool housing or as part of the housing that is more flexible than the rigid housing in conventional remote wrenches that has been shown to limit efficiency. Additionally, a fixed support and a base can be provided that are collectively capable of being coupled to the remote wrench, preferably at the flexible plate, to increase efficiency. The remote wrench operation is therefore improved by reducing inefficiencies and providing a maximum torque output.

Handles and other accessories for a remote or extension wrench that assists the user better control and maneuver the remote wrench relative to a work piece. For example, the remote wrench housing can include a handle that is coupled to the remote wrench. The handle can also be rotatable relative to the remote wrench and positionable at a desired angle of rotation for improved maneuverability.
