The inclined surface provided on the outer side of the fixed ring 8 cooperates with the inclined surface inside the threaded extrusion block 7. When the threaded extrusion blocks 7 are close to each other, they will squeeze the fixed ring 8, so that the fixed ring 8 is tightened along the inclined surface, and the interior of the fixed ring 8 contacts the outer periphery of the fixed cylinder 2. The interior of the threaded extrusion block 7 is slidably connected with a sliding column 10. The sliding column 10 is provided with five groups, which are evenly distributed inside the threaded extrusion block 7. The two groups of threaded extrusion blocks 7 are connected, and the threaded extrusion block 7 can slide up and down along the sliding column 10. The extrusion component is in contact with a fixed ring 8. A deformation notch 9 is provided on the left side of the fixed ring 8 to squeeze the fixed ring 8. The gap of the deformation notch 9 on the left side of the fixed ring 8 is reduced, and the interior of the fixed ring 8 is squeezed inward as a whole. A rounded groove 11 is provided on the top of the fixed ring 5. The rounded groove 11 is provided with five groups, which are evenly distributed in an annular shape on the top of the fixed ring 5.

[0035] Reference Figure 1 and Figure 4The shift valve 4 is provided with a shift rod 12 inside, and a shift handle 13 is slidably connected to the outer periphery of the shift rod 12. A sliding groove 14 is provided inside the shift handle 13. A sliding baffle 16 is elastically connected to the sliding groove 14 through a shock-absorbing spring 15. Two groups of shock-absorbing springs 15 are provided. One end of one group of shock-absorbing springs 15 is fixedly connected to the inner wall at the top end of the sliding groove 14, and the other end of the shock-absorbing spring 15 is fixedly connected to the top of the sliding baffle 16. When the sliding baffle 16 is not subjected to force, the upper shock-absorbing spring 15 will push the sliding baffle 16 to move downward. One end of the other group of shock-absorbing springs 15 is fixedly connected to the inner wall at the bottom end of the sliding groove 14, and the other end of the shock-absorbing spring 15 is fixedly connected to the bottom of the sliding baffle 16. When the sliding baffle 16 is not subjected to force, the lower shock-absorbing spring 15 will push the sliding baffle 16 to move upward.

The diameter of the shock-absorbing column 19 is slightly smaller than the diameter of the shock-absorbing slide groove 17. There is a certain gap between the shock-absorbing slide groove 17, so that the shock-absorbing rubber ring 20 can pass through. When squeezed, the shock-absorbing rubber ring 20 can be deformed and pass through the gap, while generating greater resistance. The outer periphery of the shock-absorbing rubber ring 20 is clamped in the interior of the shock-absorbing ring groove 18. Three groups of shock-absorbing rubber rings 20 are arranged. When the sliding baffle 16 is in a balanced state, the shock-absorbing rubber ring 20 is inside the three middle groups of shock-absorbing ring grooves 18.
[0036] Working principle: When you want to quickly disassemble and install the eight-position shift valve, place the mounting plate 3 on the fixed plate 1, and pass the fixed cylinder 2 through the mounting plate 3 and the fixed ring 5, rotate the sliding column 10, the sliding column 10 drives the threaded extrusion block 7 to rotate, and the two groups of threaded extrusion blocks 7 rotate in the thread groove 6 and move toward each other. At this time, the inner inclined surface of the threaded extrusion block 7 squeezes the outer inclined surface of the fixed ring 8, so that the fixed ring 8 is tightened along the inclined surface and the deformation notch 9 is narrowed. The fixed ring 8 squeezes and fixes the fixed cylinder 2. At the same time, the contact area is large, and the connection is relatively stable and convenient. When the equipment vibrates, the vibration is transmitted to the shift rod 12 through the shift valve 4, and the shift rod 12 drives the sliding baffle 16 to vibrate up and down. The vibrating sliding baffle 16 will continuously squeeze the shock-absorbing spring 15 on one side and stretch the shock-absorbing spring 15 on the other side to absorb the vibration and release it. At this time, the shift rod 12 and the shift handle 13 move relative to each other, and the shift handle 13 drives the shock-absorbing column 19 and the shift rod 12 to slide relative to each other. The shock-absorbing column 19 drives the shock-absorbing rubber ring 20 to slide, and the shock-absorbing rubber ring 20 is deformed and slides into the adjacent shock-absorbing ring groove 18, while generating resistance to offset the released vibration, thereby achieving the shock-absorbing effect.
