[0039] Embodiment 2 Based on Example 1, this example introduces a specific structure of a connecting component 7 in a composite bearing seat. Fig. 9As shown, the inner wall of the connecting column 20 is rotatably connected with a bidirectional screw 35, and the outer wall of the bidirectional screw 35 is screwed with two symmetrically arranged threaded sleeves 37, the outer walls of the two threaded sleeves 37 are rotatably connected with two adjustment plates 36, and one end of the four adjustment plates 36 are respectively rotatably connected to the two limit seats 24, one end of the transmission shaft of the rotating part 4 is fixedly connected to the bidirectional screw 35, and the bidirectional screw 35 is driven to rotate by the rotation of the rotating part 4. When the bidirectional screw 35 rotates, it directly drives the two threaded sleeves 37 to move toward or away from each other. When the two threaded sleeves 37 move toward each other, the limit seat 24 is directly driven to extend through the adjusting plate 36.

[0040] Working principle: When in use, fix the base 1 at the specified position through the mounting ear 2 on the base 1, and then install the mounting base 3 on the base 1. When installing, first insert the connecting column 20 into the rib groove 11 on the support base 10. When the connecting column 20 is fully inserted into the rib groove 11, rotate the rotating part 4. When the rotating part 4 rotates, it directly drives the screw rod 21 to rotate. When the screw rod 21 rotates, it drives the trapezoidal block 22 to move downward. When the trapezoidal block 22 moves downward, it directly pushes the two limit seats 24 to be inserted into the limit groove 12 through the driving plate 23, so as to facilitate fixing the mounting base 3 on the support base 10, or rotate the rotating part 4 to drive the bidirectional screw 35 to rotate. When the bidirectional screw 35 rotates, it directly drives the two threaded sleeves 37 to move toward or away from each other. When the two threaded sleeves 37 move toward each other, they are directly pushed through the adjustment plate 36 to insert the two limit seats 24 into the limit groove 12. When the seat is vibrated during use, the mounting seat 3 moves down through the supporting seat 10. When the supporting seat 10 moves down, the two sliding seats 14 are pushed apart by the two connecting plates 18. When the sliding seat 14 moves apart, the spring 15 on the mounting rod 13 is directly compressed. At the same time, the driving seat 26 compresses the airbag 27, and cooperates with the damper 17 to buffer and reduce shock on the mounting seat 3. When the shock absorbing mechanism 9 is used for a long time, the shock absorbing effect decreases. At this time, the shock absorbing mechanism 9 is adjusted. During the adjustment, the air pressure in the airbag 27 is directly adjusted through the pneumatic component 8. When the airbag 27 is inflated, the air pressure pushes the sealing plug 34 open, and the air flow enters the airbag 27. When the inflation stops, the cooperation between the air pressure in the airbag 27 and the spring 2 33 makes it convenient to directly close the connector 30 through the sealing plug 34, thereby avoiding air leakage in the airbag 27.
