The limiting rod 9 slidably connected to the inner wall of the connecting plate 1 can move, and by providing the limiting gear ring 7 and the limiting rod 9, the rotation of the fastening nut 5 can be restricted, thereby increasing the reliability of the use of the rotating shaft.

[0031] The following is a detailed description of its overall specific settings and functions.

[0032] like Figure 1-Figure 5As shown, the surface of the limiting rod 9 is covered with a first spring 10, and the two ends of the first spring 10 are fixedly connected to the mounting plate 8 and the connecting plate 1 respectively. By providing the mounting plate 8, the first spring 10 can be easily installed, and by providing the first spring 10, the position of the limiting rod 9 can be easily limited. A sliding groove is provided on the side of the connecting plate 1 away from the fastening nut 5, and a slider 16 is slidably connected to the surface of the sliding groove on the connecting plate 1, and a moving block 11 is fixedly connected to the side of the slider 16 close to the washer 6. The slider 16 slidably connected to the surface of the sliding groove on the connecting plate 1 can move, thereby ensuring that the moving block 11 can move. A mounting hole is provided on the side of the moving block 11 away from the connecting plate 1, and a sliding block 13 is slidably connected to the surface of the mounting hole on the moving block 11, and the inner wall of the sliding block 13 is fixedly connected to the moving rod 14. The sliding block 13 slidably connected to the inner wall of the moving block 11 ensures that the moving rod 14 can move closer to or away from the connecting plate 1.

[0033] The side of the sliding block 13 away from the connecting plate 1 is fixedly connected to the pressure plate 12, and the inner wall of the slider 16 is slidably connected to the fixed rod 17, and the fixed rod 17 is fixedly connected to the surface of the slide groove on the connecting plate 1. By providing the sliding block 13, the pressure plate 12 can be connected to the connecting plate 1 while ensuring that the pressure plate 12 can move. The surface of the moving rod 14 is covered with a second spring 15, and the two ends of the second spring 15 are respectively fixedly connected to the moving block 11 and the sliding block 13. By providing the second spring 15, the position of the sliding block 13 can be limited, and by providing the moving rod 14, the position of the second spring 15 can be limited. The surface of the fixed rod 17 is covered with a third spring 18, and the two ends of the third spring 18 are respectively fixedly connected to the slider 16 and the connecting plate 1. By providing the third spring 18, the position of the slider 16 can be limited, and by providing the fixed rod 17, the position of the third spring 18 can be limited.

[0034] Working principle: When assembling a high-reliability shaft, first move the shaft body 2 through the connecting plate 1, then control the moving block 11 to drive the slider 16 to slide on the surface of the fixed rod 17, so that the connecting block and the pressure plate 12 move away from the shaft body 2, and move the washer 6 close to the shaft body 2, release the moving block 11, and under the action of the elastic force of the third spring 18, the moving block 11 and the pressure plate 12 move close to the washer 6, and at the same time, under the action of the elastic force of the second spring 15, the sliding block 13 and the moving rod 14 drive the pressure plate 12 to temporarily limit the position of the washer 6, and then the first gasket 3 and the second gasket 4 are sleeved on the shaft body 2, and the limiting rod 9 is moved to make the mounting plate 8 move close to the connecting plate 1, and the fastening nut 5 is sleeved on the shaft body 2, and the fastening nut 5 is rotated to make it close to the second gasket 4, and then the limiting rod 9 is released, and under the elastic force of the first spring 10, the mounting plate 8 is moved close to the connecting plate 1. Under the action, the limit rod 9 moves close to the limit gear ring 7. At this time, the limit rod 9 limits the rotation of the fastening nut 5 through the limit gear ring 7, completing the assembly of the high-reliability rotating shaft. In the process of the pressure plate 12 moving close to the washer 6, the washer 6 pushes the pressure plate 12 through the inclined surface of the pressure plate 12, driving the sliding block 13 and the moving rod 14 to move away from the connecting plate 1. By setting the limit gear ring 7 and the limit rod 9, the rotation of the fastening nut 5 can be restricted, thereby ensuring that the high-reliability rotating shaft will not loosen during use as much as possible, thereby ensuring the reliability of the use of the rotating shaft as much as possible. By setting the moving block 11 and the pressure plate 12, the position of the washer 6 can be temporarily restricted during the assembly of the high-reliability rotating shaft, thereby facilitating the assembly of the high-reliability rotating shaft by the staff and improving the efficiency of assembling the high-reliability rotating shaft.
