A method and apparatus is provided for adjusting a latch. An apparatus comprises a latch body, a first member, and a second member associated with the latch body. A receiving area extends through at least a portion of the latch body. The first member is configured to be at least partially received within the receiving area of the latch body. The first member has a first coupling element. The second member has a second coupling element. Movement of the first member along an axis through the receiving area changes a distance between the first coupling element and the second coupling element.

An object of the present invention is to provide a bolt connector that enables a bolt to be inserted into a high nut, and is capable of easily maintaining a connection state between the bolt and the nut. The bolt connector connects two bolts and is configured by: a high nut that has a female screw portion; and a spring that is partially inserted into the female screw portion. The female screw portion is formed having a larger diameter than an outer diameter of the bolt. The spring is formed into a shape in which the spring is in contact with threads of the female screw portion and a male screw portion of the bolt, in a state in which the bolt or the high nut is rotated and fastened.

A Samer rod has length adjustable along a longitudinal axis. A first element extends along the axis between a first coupling end and an engagement section end, and a second element extends along the axis between a second coupling end and a receiving end. A receiving hole extends along the axis, inside the first element, away from the receiving end to the second coupling end. The engagement section has an outer row of teeth extending parallel to the axis with evenly spaced teeth extending perpendicular to the axis in the circumferential direction of the engagement section. The receiving hole has an inner row of teeth extending parallel to the axis with evenly spaced teeth extending perpendicular to the axis in the circumferential direction of the receiving hole wall. The spacing of the teeth of the two rows in the direction of the axis corresponds to one another.

A swivel attachment and/or branch line restraint device with angular versatility and mobility for facilitating connection of installation components to support a pipe or other load relative to a support surface is provided. Advantageously, embodiments of the device provide a plurality of rotational or swivel degrees of freedom, which are substantially independently controllable, for its mating portions, which respectively engage corresponding mating portions of other installation components. The device embodiments can desirably be configured in male-female, male-male or female-female arrangements to enhance device utility and/or versatility, thereby advantageously allowing for use in a myriad of applications and installations, such as construction, utilities and the like, among others, to reliably support loads.

A building block structure includes a joint adaptor unit and at least one connection bar. The joint adaptor unit includes one or multiple joint adaptors, each of which includes at least one screwing connection end that includes a right/left-hand combined threaded hole formed therein. The right/left-hand combined threaded hole includes multiple right-handed screw troughs and multiple left-handed screw troughs that are alternately arranged. The connection bar has one end having multiple spaced right-handed external threads and an opposite end having multiple spaced left-handed external threads. As such, when the connection bar is rotated in a given direction, the right-handed external threads and the left-handed external threads are simultaneously screwed into the right/left-hand combined threaded holes of two oppositely facing joint adaptors. Through rotation in an opposite direction, the right-handed external threads and the left-handed external threads are simultaneously disengaged from the right/left-hand combined threaded holes.
