The utility model provides an angle adjustable connecting structure, the connecting seat includes two opposite setting webs, the assembly space of accommodating connecting head is formed between two opposite setting webs, is provided with the open type coordination hole on the connecting head, and the connecting head stretches into the assembly space of connecting seat, and the fastening assembly includes special-shaped pivot and fastening screw, special-shaped pivot is adapted with special-shaped assembly hole, and special-shaped pivot and fastening screw are two thread cooperation clamping connecting seat and are fixed with connecting seat, open type coordination hole and special-shaped pivot are opposite fixed under the locking state. Through special-shaped assembly hole and special-shaped pivot cooperation locking, make special-shaped pivot not rotate relative to special-shaped assembly hole, improved the stability of angle after adjusting, utilize the open size of open type coordination hole of adjusting assembly and adjust, on the one hand, facilitate assembly, on the other hand, improved the stability of open type coordination hole and special-shaped pivot opposite fixed, and further improved the stability of angle after adjusting.

The utility model relates to the technical field of luggage accessories, in particular to a luggage cup holder assembly convenient for height adjustment, which comprises a fixed plate body fixed on a luggage and a movable plate body rotationally connected to the lower end of the fixed plate body and used for bearing a cup body, and a cup holder body is hinged to the upper end of the fixed plate body. A first containing groove for containing the cup holder body is formed in the fixed plate body, the cup holder body comprises a rotating seat rotationally connected to the fixed plate body, a left cup holder and a right cup holder are arranged in the rotating seat, and mounting cavities are formed in the side walls, located on the two sides of the left cup holder and the right cup holder, of the first containing groove. An adjusting structure capable of promoting the left cup holder and the right cup holder to ascend and descend along the mounting cavity is arranged in the mounting cavity. The luggage cup holder assembly with the height convenient to adjust has the advantages that the height can be adjusted, so that the adaptability and the stability are improved.

The utility model discloses a finish rolling nut fastener which comprises a threaded pipe and further comprises a fixing pipe arranged on the side wall of the threaded pipe, the fixing pipe is provided with a rotating assembly used for rotating the threaded pipe, and the rotating assembly comprises a fixing cavity formed in the fixing pipe. A plurality of through holes arranged in an annular array are formed in the inner wall of the side, away from the threaded pipe, of the fixing cavity, rotating plates are slidably connected to the through holes, and the fixing cavity is provided with a limiting assembly used for limiting the rotating plates. According to the wrench, through the arrangement of the rotating assembly, the nut is fastened and loosened, meanwhile, the worn rotating part is replaced through the arrangement of the limiting assembly under the matching action of the driving assembly, the extruding assembly and the pushing assembly, and therefore the nut fastening part can be conveniently replaced while the rotating effect of the wrench on the nut fastening part is kept; and the scrap probability of the nut is reduced, so that the use long-term effect of a nut fastener is improved.

The utility model provides an assembly type axis and eccentricity reciprocating tension-compression test device suitable for structural members, and belongs to the technical field of building structures. The problem that an existing test device can only achieve monotonous compression or monotonous tension working conditions and cannot achieve reciprocating tension-compression test loading is solved. The device mainly comprises a loading equipment connecting part, a test component connecting part and a test component, so that the problems that the end part of a structural component is easy to damage in advance during reciprocating pull-press loading, pull-press load transmission is insufficient and the like are effectively solved, and effective transmission and conversion of the pull-press load in a metal pipe-concrete combined component are ensured; the position of the pulling-pressing rotating shaft is adjusted through the eccentricity adjusting shaft. According to the utility model, the tension-compression reciprocating load with any eccentricity can be applied to the structural member, the assembly type mechanical connection is adopted, the assembly operation of the test device is convenient, the rapid installation and rapid replacement of the test member and the loading device can be realized, and the extra workload in the test process is reduced.
