[0028] In this embodiment, the pressure on the upper part of the lifting plate 3 is buffered and adjusted by the telescopic spring 55 and the buffer spring 64 arranged on the first buffer component 5 and the second buffer component 6. First, the pressure is transmitted to the telescopic spring 55 through the upper fixed block 54, and the telescopic rod 53 and the telescopic spring 55 shrink. When the pressure on the lifting plate 3 is too large, the connecting block 63 transfers part of the pressure to the slider 62 through the connecting plate 65, and the pressure is divided by the buffer spring 64. Then, the pressure is transmitted to the hydraulic lifting rod 8 at the bottom of the buffer plate 2, thereby buffering the top connection force of the hydraulic lifting rod 8 and improving the service life of the hydraulic lifting rod 8.

[0029] In this embodiment, the left and right sides of the lifting plate 3 are fixedly connected with fixing ears 4, and both ends of the surface of the bottom plate 1 are provided with lifting auxiliary components 7, and the lifting auxiliary components 7 include a rotating motor 71 fixedly installed on the surface of the bottom plate 1, and the output end of the rotating motor 71 is fixedly connected with a threaded rod 72;

There are settings on both sides of the threaded rod 72 to balance the forces on both sides, further extending the service life of the hydraulic lifting rod 8.

[0033] Working principle of the utility model: the utility model is a buffered hydraulic lifting and jacking mechanism. When the lifting plate 3 is under pressure, the pressure is first transmitted to the telescopic spring 55 through the upper fixed block 54, and the telescopic rod 53 and the telescopic spring 55 shrink. When the pressure of the lifting plate 3 is too large, the connecting block 63 transmits part of the pressure to the slider 62 through the connecting plate 65, and the pressure is divided by the buffer spring 64. Then the pressure is transmitted to the hydraulic lifting rod 8 at the bottom of the buffer plate 2, thereby buffering the jacking force of the hydraulic lifting rod 8. The rotating motor 71 and the hydraulic lifting rod 8 run synchronously, which can make the lifting plate 3 move up and down, and the rotation of the threaded rod 72 makes the lifting plate 3 rise and fall, reducing the pressure burden of the hydraulic lifting rod 8. Both sides of the threaded rod 72 are set to balance the forces on both sides, thereby improving the service life of the hydraulic lifting rod 8.
