This utility model discloses a carpet edge-pulling and wrinkle-preventing device, including a first fixed end and a second fixed end. A fixed beam is fixedly connected to the first fixed end, and a fixed box that slides with the fixed beam is fixedly connected to the second fixed end. It also includes a drive mechanism disposed within the second fixed end. The drive mechanism includes a motor and a second hammer plate. When the motor operates, it drives the second hammer plate to reciprocate, causing the second hammer plate to repeatedly strike the first hammer plate at the inner end of the fixed beam. This causes the first and second fixed ends to move outward relative to each other, flattening the carpet pressed against the first and second fixed ends. This utility model, by setting up a drive mechanism, uses a motor-driven cam to drive the second hammer plate to reciprocate and strike the first hammer plate, achieving automatic flattening of the carpet edge. This process eliminates the need for manual knee-bumping of the carpet support, significantly reducing operational difficulty and reliance on worker skill, while also avoiding knee injuries caused by manual impact.

Matching holes are formed in the two side walls of the fixing plate in the vertical direction, and fixing bolts penetrate through the adjusting holes of the arc-shaped plate and then are connected with the matching holes of the fixing plate in a matched mode. The upper body posture of a patient can be adjusted at any time, the patient is prevented from feeling tired, treatment of the patient is facilitated, the structure is simple, use is convenient, and practicability is high.

The utility model relates to the technical field of museum digital display boards, and discloses an adjustable museum digital display board which comprises a base, an operation table is arranged at the top of the base, an L-shaped connecting frame is arranged at the bottom of the operation table, and a seat cushion is arranged outside the L-shaped connecting frame. According to the adjustable museum digital display board, a driving assembly is arranged, a servo motor is started to drive a second bevel gear to rotate through an output shaft, and through cooperative use of the second bevel gear and a first bevel gear, a threaded rod rotates to drive an upper threaded block and a lower threaded block to move relatively; through cooperative use of an upper threaded block, a lower threaded block, an X-shaped connecting rod, an upper sliding block and a lower sliding block, an L-shaped connecting frame drives a seat cushion to move out, then researchers can have a rest, knee injuries caused by long-time standing are avoided, meanwhile, compared with a traditional seat, the situation that the seat is taken away for use and affects rest can be avoided, the practicability of the device is improved, and the device is worthy of popularization. The use by workers is convenient.

The application provides a knee cartilage injury grading method and a storage medium thereof. The knee cartilage MRI image of a patient is acquired, and image region segmentation is performed on the knee cartilage MRI image to obtain a first image representing a patellofemoral joint region, a second image representing a medial femorotibial joint region, and a third image representing a lateral femorotibial joint region in the patient. Feature extraction is performed on the first image, the second image, and the third image to obtain a first feature set. The first feature set is input into a radiomics model, and the first feature set is subjected to cartilage injury grading evaluation and evaluation explainability analysis by the radiomics model to obtain a knee injury score and a knee injury grade of the patient and a visual evaluation report for explaining the generation of the knee injury score and the knee injury grade. The knee cartilage injury grading accuracy and explainability evaluation are realized, and the grading accuracy and the clinical application reliability are improved.
