After the limiting seat 7 is placed on the top of the support plate 6, the second fastening bolt 21 is threadedly connected to the mounting hole 13, and the limiting seat 7 can be fixed. Fixed, the support adjustment rod 502 can support and fix the limiting side plate 503, the limiting side plate 503 can directly fix and limit the frequency converter, the fastening screw 506 can be threadedly installed in the inner cavity of the adjustment groove 505 to fix the limiting side plate 503, the first protective block 2 can protect the outer surface of the shockproof mechanism 1, the inflation pump 11 can inflate the inflatable airbag 105, and the inflatable airbag 105 can directly contact the bottom of the support plate 6, thereby improving the buffering effect.

[0046] In summary, the overall beneficial effects of the embodiment are as follows: the shockproof mechanism 1 achieves multi-level shock absorption protection by combining the buffer pad 101, the damping vibration reduction spring 102 and the inflatable airbag 105. The evenly distributed buffer pad 101 ensures load balance, the damping vibration reduction spring 102 effectively absorbs vibration energy, and the adjustable inflatable airbag 105 provides a customized shock absorption effect.
