[0037] Working principle: when using the installation structure, the leather cup 2 is set inside the self-installing component body 1, and then the installation component is sleeved on the surface of one end of the installation shaft, and then the leather cup 2 is sleeved on the surface of one end of the shaft, so that during the operation of the aircraft engine, because there are various fluids and pressure transmission and control inside, the good sealing of the leather cup well ensures the efficiency and stability of these processes. When using the limit device 3, the first threaded rod 309 is manually controlled to rotate, because the thread direction on the surface of the first threaded rod 309 is opposite from the middle to both sides, so that it can be simultaneously passed through the connecting rod 30 5 drives the support rod 303 to move relative to or opposite to each other inside the sliding frame 302 at the same time, so that the connecting rod 305 is close to the end of the mounting member body 1 and the fixed arc plate 312 is pressed on the surface of the shaft. When the arc plate 312 contacts the surface of the mounting shaft, the second spring 314 is compressed, so that the rubber plate 315 is well pressed on the surface of the mounting shaft. Because the surface of the rubber plate 315 is evenly provided with notches 316, the friction between the rubber plate 315 and the mounting shaft can be well increased. Then, the sliding rod 315 fixed on the inner wall of the fixed frame 301 by manually passing the sliding frame 302 is manually 10 slides on the surface, thereby facilitating the control of the installation component body 1 to slide to the surface of one end of the shaft where the leather cup 2 needs to be installed, so that the installation component body 1 can be well sleeved on the surface of one end of the shaft, which is convenient for accurately setting the installation component body 1 on the surface of one end of the shaft. When using the connecting device 4, the second threaded rod 404 is manually controlled to rotate, thereby causing the arc plate 405 to move toward the inner wall of the installation component body 1, so that the leather cup 2 can be opened through the arc plate 405, which is convenient for sleeved on the surface of one end of the installation shaft, and the third threaded rod 413 is manually controlled to rotate. This makes it easy to control the moving block 412 to drive the fixed bar 410 to slide on the inner wall of the circular arc groove 409. At the same time, the third spring 414 squeezes the moving block 412 in the direction away from the positioning groove 411, which makes it easy to control the fixed bar 410 to be limited inside the circular arc groove 409. Because the fixed bar 410 fixes the two support plates 401 together, it is easy to control the support plate 401 to slide on the inner wall of the rectangular groove 407 at the same time. When the installation component body 1 moves on one side of the leather cup 2, it drives the ball 406 to rotate, so that the circular arc plate 405 can move well on one side of the leather cup 2. It should be noted that all damping rods in this case are retractable dampers that can absorb energy during the retraction process.
