Abstract: A rotating assembly for a displaying device allowing vertical and horizontal presentation as a user requires. A displaying assembly, a transmitting assembly, and a driving assembly are included in the displaying device. The displaying assembly includes a displaying panel and a first clamping structure, the first clamping structure includes fixing structures with tenon structures in between. The transmitting assembly includes a second clamping structure and a connecting structure, the clamping structure comprises a clamping joint, the clamping joint is coupled to the tenon structure, and fixing grooves are defined on the second clamping structure. The fixing grooves are matched with the fixing structures, an end of the connecting structure is fixedly connected to the second clamping structure. The driving assembly includes a rotating driving member, an output shaft of the driving member is connected to the connecting structure.

Abstract: A rotary device with automatic reset function for precise stopping and holding of a viewable rotating element without free play or slop remaining includes a conversion assembly, and a power assembly with output element and sensing assembly. The conversion assembly comprises a light-shielding structure with the light-shielding structure on the extension part. The power assembly with output element can drive the extension part to rotate synchronously with the light-shielding structure. The detachable sensing assembly overlaps the rotation path of the light-shielding structure, and the conversion assembly rotates at different angles so that the light-shielding structure and the sensing assembly will match at certain angles, so as to trigger a sensing signal and call up the output element. A display screen includes the rotary device with automatic reset function and a display assembly.

Abstract: A rotating device which releases in the event of overload caused by external forceful counter-rotation includes positioning assemblies, a connecting assembly, and a driving assembly. Each positioning assembly includes a positioning member and sleeving member, part of the positioning member is positioned in the sleeving member and the positioning member abuts a first abutting portion in the sleeving member. The connecting assembly has a first end carrying mounting grooves, the mounting grooves themselves carrying the positioning assemblies. The driving assembly is connected to the first end, and when an external force of a certain magnitude is received by the positioning member, the positioning member moves into the sleeving member, and the driving assembly is thereby separated from and the positioning member, preventing the driving assembly from being damaged. A rotatable display apparatus with the rotating device is also disclosed.

Abstract: An energy absorbing structure comprises a first connecting member, a second connecting member, a brittle connecting member and an elastic buffering element. The first connecting member comprises a first end portion, and the first end portion defines a first accommodating cavity. The second connecting member comprise a second end portion, the second end portion defines a second accommodating cavity, and the first accommodating cavity communicates with the second accommodating cavity to form a telescopic cavity. The first connecting member and the second connecting member are connected by the brittle connecting member, the brittle connecting member is configured for breaking during a collision to absorb the energy generated by the collision. The elastic buffering element is arranged in the telescopic cavity, and the elastic buffering element is configured to be compressed by the first connecting member and the second connecting element together to deform and absorb energy during a collision.

Abstract: A lifting structure operating precisely and stably at all stages of a lifting and lowering action includes a lifting assembly and a driving assembly. The lifting assembly includes two first links, two second links, and two seats. A first connecting arm of each first link has first and second ends, the first end having a first gear structure. A second connecting arm of each second link has third and fourth ends, a second and complementary gear structure being provided on the third end. The first gear structures are engaged and the second gear structures are engaged. The second end is rotatably connected to the fourth end through one of the two seats. The driving assembly can drive the two seats towards each other to perform lifting or drive them away from each other to perform lowering.

Abstract: A structure for holding a battery on an automated guided vehicle (AGV) so as to allow easy and convenient battery replacement includes two fixed supports and a bracket. The bracket is connected between the two supports and each support defines a vertical groove and two horizontal grooves. Two sliders at the ends of the bracket are insertable into either horizontal groove. The two sliders can move down along the vertical groove together until the bracket makes contact with the battery and holds it in place. The two sliders can move up along the vertical groove and sideways into the horizontal grooves, thereby unlatching and releasing the battery for rapid replacement. An AGV using the structure is also disclosed.

Abstract: An apparatus, for reinforcing bone and tools for mounting the same, has an implant including a barrel and a device. The implant can be expanded by an expanding apparatus including an outer tube, a base, a hollow body and a handle. The expanding apparatus can be bound to the implant to place the implant into a bone to be treated and adjust the expansion degree. The expanding apparatus can be replaced by an injector apparatus including a container for bone cement and an injecting handle. The injector apparatus can inject a mixture for reinforcing bone (e.g., bone cement) into the bone through an exit, the device, the aperture, the barrel and the window of the barrel, and into the to-be treated area.
