[0049] Working principle: First, place the device to be installed on the top of the placement plate 35. When the device is hit and causes longitudinal shaking, the placement plate 35 drives the block 34 in the square groove 11 to move up and down, so that the block 34 presses down the fixed block 3, the fixed rod 31 and the connecting rod 32, and the block 34 presses down the first spring 23 and the first damping rod 22, and then the connecting rod 32 presses down the upper support block 41 and the second spring 43, and the first spring 23 and the second spring 43 rebound upward by their own elastic effect to reset, and the first damping rod 22 and the second damping rod 42 drive the block 34 to perform buffering reset to prevent shaking. The swing amplitude is large, causing the device to shake more violently. When the block 34 is reset and the device is hit to cause longitudinal and lateral shaking, the top plate 15 acts to offset, and the top plate 15 drives the upper U-shaped member 51, the upper fixing bolt 52, the upper T-shaped member 53, the slide bar 54 and the limit block 55 to move to both ends. The slide bar 54 and the limit block 55 are located in the cylinder 56 and move, and then the elastic effect of the reset spring 563 is used to dampen the top plate 15. At the same time, the second spring 43 and the second damping rod 42 under the connecting rod 32 buffer and reset the left and right shaking of the top plate 15, thereby achieving comprehensive shock absorption. The structure is simple and easy to operate.
