The utility model relates to the technical field of rehabilitation apparatus, concretely relates to a portable wrist joint autonomous rehabilitation exercise traction device, its characterized in that: including lower arm supporting plate, palm holding plate, first mounting seat, second mounting seat, traction drive mechanism and one-way self locking mechanism, lower arm supporting plate installs on the first mounting seat, palm holding plate installs on the second mounting seat, and at least one bandage assembly is equipped on lower arm supporting plate and palm holding plate, and the second mounting seat is slidably connected with the first mounting seat through the sliding assembly, and the traction drive mechanism is used for moving the second mounting seat relative to the first mounting seat, and the one-way self locking mechanism is used for playing one-way self locking effect to the movement of second mounting seat. The utility model whole simple structure is portable, convenient operation, is suitable for family use, can realize the adjustment to the traction force, effectively ensures the stability and accurate control of traction force, can better satisfy the autonomous rehabilitation exercise demand of patient, improves rehabilitation efficiency and treatment effect simultaneously.

This utility model provides a manual inflation fixture, belonging to the field of twin-tube shock absorber equipment. The fixture includes a sleeve, which is open at one end. During use, the sleeve end face and the cylinder end face (e.g., the cylinder body end face) are on the same horizontal plane, and the piston rod inside the cylinder (e.g., the shock absorber) is inserted into the sleeve through the sleeve opening. A sealing cavity is formed between the two end faces of the sleeve to prevent gas leakage. An air inlet is provided through the sleeve side wall, with one end connected to the sealing cavity and the other end connected to an external air source. This utility model is suitable for using a simple structure to inject nitrogen into a twin-tube shock absorber to compensate for its performance. At the intersection of the piston rod and cylinder, a component is used to pry open a gap in the oil seal. The sleeve is then fitted onto the intersection of the piston rod and cylinder, forming a sealing cavity between the two end faces. Gas is injected into the sealing cavity, and the gas enters the cylinder (e.g., the shock absorber) through the gap between the oil seals.
