A mechanism for reducing time-lost to tedious but necessary adjustments while using a chainsaw is disclosed, as well as methods of manufacture and use. An embodiment has a metal part fitting inside a plastic handle portion, where the two are sometimes assembled in two halves and then pressed molded or fastened together, in the form of a pull-handle positioned at the end of a starter-cord on a chainsaw. Another embodiment has the metal part containing a flat-blade screwdriver surface at one end, which matches and mates with some type of slotted adjustment fixture within the chainsaw; and where the other end has a socket wrench which matches up with an adjustment bolt within the chainsaw. Yet another embodiment has a dog-bone (socket) wrench fitting at one end, and a flat-blade at the other end.

A torque connector structure includes a first body, a second body assembled with the first body, a first drive member assembled with the first body, a second drive member received in the first body and having a plurality of first receiving grooves each having a cylindrical shape, a third drive member received in the first body and the second body, a fourth drive member mounted on the third drive member and having a plurality of second receiving grooves, an elastic member biased between the first drive member and the second drive member, and a plurality of pins received between the first receiving grooves and the second receiving grooves. The second drive member and the first drive member are driven simultaneously.

A clench wrench has a structure including a handle and an engaging head. The engaging head defines an engaging space. A clenching device is mounted on the engaging head. The clenching device includes a resilient clenching member fixed to the engaging head and having a free end. The clenching member has a clenching portion at the free end. The free end of the clenching member is bendable to selectively clench an object. A block is disposed on the engaging head and abuts against the clenching member and counteracts a force that causes the clenching portion to move from the first position to the second position.

Sockets, for example, hexagon sockets, dodecagonal sockets, and splined sockets, that have inner surface geometries adapted to engage a flank of a fastener at a point away from a corner of the fastener. In general, the sockets engage the flank of the fastener at a distance of about 30 to 60 percent of half a length of the flank away from the corner of the fastener. This increases the strength and life of the socket, reduces a risk of the fastener becoming locked or stuck in the socket, and reduces the risk of the fastener being stripped or the socket slipping on the fastener.

A tool for torquing a regulator onto a cylinder of a portable cylinder assembly. The tool includes a nut and a socket. The nut is configured to fit around a body of a regulator of a portable cylinder assembly. As such, the nut has a first set of grooves that avoids one or more valve assemblies on the body of the regulator. The socket has a cavity extending therethrough such that the cavity consists of three sections: a top section, a middle section and a bottom section. The top section of the socket is configured to be coupled to a device that applies a torque force on the socket. The middle section of the socket is configured to avoid a case of the regulator which is disposed above the body of the regulator. The bottom section of the socket is configured to be coupled to the nut.

A socket assembly for turning a fastener with a wrench has ball mechanisms that normally engage with sides of the fastener and that can be deactivated out of engagement with the fastener by turning a collar of the socket assembly. The socket includes a socket body having a fastener receiving opening sized and shaped to engage the fastener so as to drive the fastener rotationally. At least one ball opening is provided in the fastener receiving opening adjacent the fastener when the fastener is received in the opening. A ball is provided capable of partially protruding from the ball opening with the socket in an engaged state. A ball taper insert cams against the ball to push the ball into the ball opening. A spring biases the ball taper insert so as to urge the ball into the ball opening to engage the fastener.

The inventions relates to a tool 10 that is adapted to loosen or fasten connector nuts located in areas of reduced space. The tool 10 is particularly useful because it allows manipulating basin nuts 40 located between the lower portion of the basing and piping that provides water to the faucets that are attached to the basin via the nut. The tool comprising a body having a first section adapted to receive the fastening means and a second section adapted to receive the torque, the first section and the second section being adapted for attachment to each other to transfer the torque to the first section, wherein the first section is adapted to allow piping to be located adjacent the second section during use of the tool to allow the first section to receive the fastening means. The tool may be configured as a socket. The invention also relates to a kit including the sockets.
