The utility model discloses a sitting posture chest pushing training device grip angle adjusting mechanism which comprises a shell, an adjusting ring, a rotary disc and a grip assembly, one end of the shell is provided with an opening, one end of the adjusting ring is fixedly connected with the end, provided with the opening, of the shell, a plurality of adjusting holes distributed in a surrounding mode are sequentially formed in the adjusting ring, and the rotary disc is arranged on the rotary disc. Any two adjacent adjusting holes are communicated through a slide way; the turntable is rotationally connected with the other end of the adjusting ring; the grip assembly comprises a grip pipe, a top pressing rod, a clamping head, a pressing head, a limiting ring, a baffle ring and a spring. Therefore, the adaptability and comfort of fitness operation can be effectively enhanced, a body builder can easily adjust the angle of the grip according to the body conditions of the body builder, and therefore muscles can be exercised more accurately and fully in the training process; meanwhile, the problem of uneven stress caused by improper postures can be effectively avoided through the reasonable grip angle, and the sports injury risks such as muscle strain and joint sprain are greatly reduced.

The application discloses a postoperative remote monitoring and rehabilitation system for thoracic surgery patients based on informatization, and relates to the technical field of postoperative monitoring.The system solves the technical problems that traditional monitoring cannot perceive the stress problem of sternal incision caused by improper posture, lacks real-time early warning models based on electrocardio characteristics, is difficult to discover acute events in time, and is difficult to make rehabilitation plans fit the actual situation, easily causes blind decision-making and cannot be dynamically adjusted due to fixed grouping, non-causal models and lack of optimization algorithms.The system dynamically correlates the body position angle and the thoracic pressure, calculates the thoracic load index and the sternal incision stress concentration index in real time, can quantify the cumulative stress of the sternal incision caused by improper posture, identifies influencing factors through the SCM structure causal model, constructs a rehabilitation data topology graph for each group, identifies key factors affecting the rehabilitation effect through causal inference, instead of only discovering correlation, provides a scientific basis for precise intervention, and avoids wrong decisions.

The utility model discloses a safe electric pruning shears uses, belongs to electric pruning shears technical field, aims at solving the stress of transmission part (gear, shaft etc. ) in prior art is difficult to distribute evenly, and local stress concentration can accelerate gear, shaft wear, shorten component life, more key is, under uneven stress state, the connected blade will shake, shift, on the one hand, cause the unevenness of incision, difficult accurate control blade track and shearing force, and the poor pruning quality will make plant wound difficult to heal, increase the risk of pathogenic infection, threaten the safety of plant growth, on the other hand, the abnormal shaking of blade can easily make the operator hand fatigue, slip, and even possibly because of blade out of control, injure the human body, there is the hidden danger of operation safety, at the same time, the stress problem can also increase the failure rate of bearing parts, and frequent failure not only delays the operation, also makes the equipment stability decline, further amplifies the problem of safety risk. Including pruning shears aluminum frame body, the upper portion of pruning shears aluminum frame body is equipped with aluminum dress dish.
