[0017] With general reference to the drawings, various embodiments of a turning tool are shown. In several embodiments, the turning tool has a hollow core (for example, a central through-hole extending between opposite ends of the turning tool handle). The hollow-core turning tool allows the driving of a fastener (for example, a nut) along an elongated threaded workpiece or shaft that extends through the hollow core of the turning tool during use. In certain embodiments, the openings at both ends of the handles include drive surfaces (for example, hexagonal drives) for driving in a fastener. In several embodiments, the turning tool includes one or more insert tubes held by the handle, allowing the tool to be used to drive fasteners of various other sizes.

[0018] For example, the hollow-core turning tools described here allow the turning tool to be moved around and along a large shaft, such as a threaded shaft several feet long, until the turning tool engages a fastener, such as a bolt and / or nut, even if the fastener is located a considerable distance (for example, several inches or more) from the end of the shaft. In this way, the hollow-core turning tools allow users to engage fasteners with a hand-held turning tool, rather than using other tools, such as pliers, to secure the fasteners to the shaft.As will be described below, one or more of the hollow core turning tools described herein include one or more plug-in insert tubes that can be coupled to one end of the handle and / or other plug-in insert tubes to provide users with a wide range of plug-in insert sizes that can be used with the hollow core turning tools.

[0019] With reference to Fig. In one embodiment, the turning tool comprises a handle with a hollow core / central through-hole and hollow-core insert tubes extending from opposite ends of the handle. In one embodiment, the turning tool includes primary hollow-core insert tubes that are non-reversible. In another embodiment, the turning tool includes primary hollow-core insert tubes that are reversible. Secondary reversible hollow-core insert tubes can engage with the primary insert tubes. These embodiments allow the user to select the desired insert size to drive a nut of a specific size along the elongated workpiece. In a specific embodiment, the turning tool may also include a tertiary insert tube that engages with the secondary insert tubes.

[0020] With reference to Fig. Figures 1 through 5 show different aspects of a turning tool, such as turning tool 110. The turning tool 110 defines a channel 112 that extends through the turning tool 110. The channel 112 is collectively defined by the one or more components of the turning tool 110 that are in use at any given time. When tightening a fastener, such as a nut or bolt head, on a relatively long shaft (for example, several feet long), the user can adjust the turning tool 110 to include a socket end that engages with the fastener and then slide the turning tool 110 along the long shaft as the shaft extends through the channel 112 until the turning tool 110 engages with the fastener.In this way, users can use the rotary tool 110 to tighten and / or loosen fasteners that are located far from one end of the respective shaft.

[0021] The rotary tool 110 comprises a handle 120, a first primary insert tube 130, a second primary insert tube 140, a first secondary insert tube 150, a second secondary insert tube 160, and a first tertiary insert tube 170. The various insert tubes can be coupled to the handle and / or to each other to provide the user with several different insert sizes (for example, several hexagonal inserts) that engage with fasteners of different sizes. In various embodiments, the fastener is selected from the group consisting of a screw head and a nut.

[0022] For example, when using the device, a user first identifies the size of a fastener to be tightened or loosened. The user then identifies the insert end to engage with the fastener from among the insert ends defined by the handle 120, the first primary insert tube 130, the second primary insert tube 140, the first secondary insert tube 150, the second secondary insert tube 160, and the first tertiary insert tube 170. The user can optionally couple one of the primary insert tubes 130 or 140 to the handle 120, optionally also couple a secondary insert tube 150 or 160 to the primary insert tube 130 or 140, and optionally also couple the first tertiary insert tube 170 to the secondary insert tube 150.The handle 120 and the selected plug-in insert tubes, if any, together define the channel 112, which extends through the entire rotary tool 110. Finally, the user pushes the handle 120 and the selected plug-in insert tubes, if any, along the shaft until the rotary tool 110 engages in the fastener.

[0023] The handle 120 comprises a first socket end 122, an opposing second socket end 124, and a first channel 126 extending through the handle 120 between the first socket end 122 and the second socket end 124.

In particular, the turning tool 410 is identical to the turning tool 310, except for the differences described here, which include a recess 437 and a projecting component, shown as a ring 438, instead of a shoulder 386.

[0048] The turning tool 410 comprises a handle 420, a tool holder 430, and a shank 440. The handle 420 comprises a first socket end 422 defining a diameter 424. The tool holder 430 comprises a first end 432 opposite the second socket end 434, an engagement section 436 engaging with the first socket end 422, a recess 437 defined within the first end 432, and a ring 438 that is at least partially located within and projects from the recess 437. In various embodiments, the ring 438 is selected from the group consisting of a wire ring, for example, a metal wire ring, and a C-clip. In various embodiments, the recess 437 defines a ring extending around the first end 432. In various embodiments, the recess 437 is formed by cutting into the first end 432.The shaft 440 comprises a second end 442 and an opposing third insert end 444. The recess 437 defines an outer surface 450 of the tool holder 430, and the ring 438 defines an outer surface 452 that engages with the outer surface 450 defined by the recess 437. In various embodiments, the first insert end 422 is configured to receive and engage the first end 432, such that the projecting component, represented as the ring 438, rests against the first insert end 422 to prevent further insertion of the tool holder 430 into the first insert end 422.

[0049] The ring 438 defines a diameter 439 that is larger than the diameter 424. Consequently, the ring 438 prevents the tool holder 430 from engaging with the first socket end 422 when the second socket end 434 is inserted into the first socket end 422, because the ring 438 prevents the tool holder 430 from being inserted into the first socket end 422 to the point where it engages with the inner surfaces of the first socket end 422.

[0050] In one embodiment, the ring 438 is a collar that extends completely around an outer surface 433 of the body 431 of the tool holder 430. In another embodiment, the ring 438 is a ring that is coupled to an outer surface 433 of a body 431 of the tool holder 430. In various embodiments, the ring 438 is a ring with an outer surface 452 that engages with an outer surface 450 defined by the recess 437.
