The side of the main body 1 is provided with an embedded groove 13, and a buffer top plate 14 is embedded in the embedded groove 13. The middle of the rotating slide bar 18 is provided with symmetrical thread sections, the middle of the rotating slide bar 18 is sleeved with a limiting slide block 21 matched with the thread sections, and a third spring 20 is arranged between the limiting slide block 21 and the sliding connection block 17. The rotary slide bar 18 penetrates out of the top of the shockproof seat 2, and the top of the rotary slide bar 18 is provided with a rotary block 22.

The working principle is as follows:

an operator uses a tool to rotate the adjusting block 10, the adjusting block 10 drives the threaded rod 9 to rotate, and the threaded rod rotates 9 to enable the limiting clamping block 12 to move back to back. After the limiting clamping block 12 moves for a certain distance, the main body 1 is placed on the supporting plate 3. At this time, the threaded rod 9 and the adjusting block 10 descend along the lifting chute 11, and the buffer telescopic rod 7 and the first spring 8 are compressed.

An operator uses a tool to rotate the adjusting block 10, the adjusting block 10 drives the threaded rod 9 to rotate, and the threaded rod rotates 9 to enable the limiting clamping block 12 to move oppositely, so that the limiting clamping block 12 is connected with the fixing lug to fix the main body 1.

When the main body 1 is vibrated and vertically moves, the main body 1 drives the supporting plate 3 to ascend and descend, and the supporting plate 3 directly acts on the buffering telescopic rod 7 and the first spring 8 through the connected translation sliding rod 5. When the buffering telescopic rod 7 and the first spring 8 are stressed to be compressed or extended, elastic force or pulling force is generated to act on the translation sliding rod 5, and then acts on the main body 1 to reduce or offset vibration force in the vertical direction.

Horizontal direction, main part 1 passes through backup pad 3 and removes along translation slide bar 5, and main part 1 extrudees one side buffer roof 14 simultaneously, and buffer roof 14 atress extrudees sliding connection piece 17 through fixed connection piece 15 and connecting rod 16, and sliding connection piece 17 slides and extrudees second spring 19 along rotating slide bar 18, and second spring 19 pressurized produces elasticity and then reduces or offset the effort, realizes alleviating receiving vibrations and influences.
