A multipurpose tool for handles and valves has been designed to facilitate the operation of outdoor water faucets (sillcocks, cocks, spigots, bibs, taps) and water splitters (diverters, wyes). Metal fingers (pins, tines) on the tool fit into or onto window, tee, and cross tee handles to open or close water faucets. Other metal fingers fit onto various shapes of levers to open or close water splitter valves. The valve fingers also work as a wrench to tighten or loosen the nut securing most faucet handles to the spigot. Both types of fingers can be used to scoop out damaged leaky washers. The tool arm has a metal file surface to smooth rough faucet edges that touch washers, often a place where water leaks occur. Finally, the hollow tool handle contains extra plumbing sealing tape and washers for onsite faucet and hose repairs.

A wrench head for a universal wrench is disclosed that may include a housing having an upper portion and a lower portion. The wrench head may further include a base plate positioned inside the housing towards the upper portion of the housing, and a plurality of push-rods positioned inside the housing. The wrench head may further include a resilient member positioned inside the housing between the base plate and the distal end of each of the plurality of push-rods. In the default position, the resilient member biases each of the plurality of push-rods, and in the retracted position, the proximal end of each of the plurality of push-rods is pushed against the resilient member to be received along with a portion of the resilient member by a compartment of the plurality of compartments defined at the bottom surface of the base plate.

The invention provides a dual-purpose handle, comprising a body, wherein mounting holes are provided in the body and are used for connecting to functional members; the mounting holes are provided in the body in both an axial direction and a radial direction; axial and radial mounting holes provided in the body can enable the handle and the functional members to easily and quickly switch between two connection forms, i.e. straight and T-shaped; and torsional torques that are different in magnitude can be output by means of different connection manners under the action of the same operation force. Clamping devices fitted with the functional members are arranged in the mounting holes; and when the functional members are connected to the handle, the clamping devices can fix the functional members and prevent same from rotating in a cavity of the body of the handle. The axial and radial holes of the handle are configured to be through holes, so that the handle can be adapted to guide needles of different sizes passing through same and is suitable for minimally invasive surgery, thereby further expanding the range of use of the handle.

A pair of screwdrivers each having a handle, a nondetachable outer shaft, a detachable inner shaft, and at least two detachable double-ended screwdriver bits. Each screwdriver handle is formed having a hollow space configured to substantially house the outer screwdriver shaft, the inner screwdriver shaft, and the at least two double-ended screwdriver bits of the other screwdriver, whereby, the pair of screwdrivers may be assembled together when not in use so that the outer shaft, the inner shaft, and the at least two double-ended screwdriver bits of both screwdrivers are substantially non-exposed to prevent the potential for accidental user injury.
