The application discloses a short-tail ring groove rivet assembly and an assembling method thereof. The rivet is a rotary body integrally formed, and sequentially comprises a rivet cap head, a smooth rod section, a ring locking groove section, a pull groove section and a short tail section in the axial direction. The ring locking groove section is a continuous and equal-tooth-shaped annular groove structure without a thread structure. The sleeve ring is a hollow rotary body integrally formed, and sequentially comprises a flange section and a plastic deformation zone in the axial direction. An elastic tooth part is arranged on the inner hole side wall of the tail end of the sleeve ring. The rivet assembly adopts a full ring groove structure, and the elastic tooth part with a guide inclined surface and a locking clamping surface is designed on the sleeve ring. The pre-assembly is realized by replacing the traditional "circumferential rotation and screwing" with "axial pushing". The application also provides various tooth structure forms, such as a single tooth type, a circumferential segmented type and a continuous ring type, so that the application can be flexibly selected according to different working conditions, the processing technology is simplified, the assembling efficiency is improved, and the locking reliability and cost control in different scenes are considered.

The utility model relates to the technical field of medical instruments, in particular to a knee joint tibial plateau implanting device which comprises an implanting device body and a jackscrew, and the jackscrew is in threaded connection with the implanting device body through a through hole. The short tail is connected with the outer side edge of the tail end of the jackscrew through an easy folding line, and the short tail extends in the direction away from the jackscrew in the length direction of the jackscrew. By arranging the short tail structure, the pre-assembly time of the jackscrew is shortened, meanwhile, the short tail is connected with the jackscrew through the easy-to-fold line, after the jackscrew is successfully pre-assembled, the short tail is broken off from the easy-to-fold line, so that the short tail is separated from the tail end of the jackscrew, and then it can be guaranteed that the implant can be smoothly implanted into the human body.

Rubber fishing lures (delayed sinking) characterized by The addition of a tail plate creates a wobbling action, slowing the lure's descent. The tail plate of a soft plastic lure typically serves to attract the attention of a predatory fish through its back-and-forth movement. For manufacturing reasons, the plate's surface is flat. The innovation is that the tail plate is concave on the inside, like a parachute (1). This slows down the fall of the soft plastic lure with jig head rig, leading to an increased number of bites, since approximately 99% of bites occur during the lure's fall. The curved tail plate (1) contains a volume of water that dampens the back-and-forth wobble of the plate because the enclosed water mass must also move. The innovation lies in the fact that on both sides of the tail plate, which is connected to the body of the soft plastic lure at the upper end of the caudal peduncle, there is a rearward-facing, curved outlet channel (1a) through which the water collected in the cavity of the concave tail plate can escape. These two outlet channels result in a significantly higher frequency wobble of the tail plate. The tail plate is connected to the soft plastic lure at its upper end by a short, flat, vertical caudal peduncle. This short caudal peduncle transfers the vibrational energy of the tail plate to the soft plastic lure, causing it to also wobble back and forth.Long, thin tail stalks may make the plate wobble more, but almost no kinetic energy is transferred to the fish's body. The kinetic energy remains in the tail plate. The protection applies to lure lengths between 30mm and 300mm. The length of the tail stem, excluding the tail plate, can be between 5% and 25% of the lure's total length. The diameter of the tail plate can be between 5% and 20% of the lure's total length. The tail plate can be round, oval, elliptical, heart-shaped, teardrop-shaped, square, or rectangular. The angle of the tail plate to the soft plastic lure is between 70 and 120 degrees (1c).
