For this reason, it is necessary to add a buffer design to the connection of the product to reduce the impact acceleration to a certain extent so that the product can withstand strong impact. At the same time, it is also necessary to consider that the weight reduction of the product cannot exceed a certain value. Summary of the invention

A plurality of cylindrical pins 12 are provided on both ends of the upper connecting plate 4, and the cylindrical pins 12 at the ends of the upper connecting plate 4 pass through the ends of the upper connecting plate 4 and fix the corresponding load-reducing springs 5, transition springs 6 and main springs 7 provided on the upper connecting plate 4. Similarly, on the lower connecting plate 3, transition springs 6 are provided on both sides of each group of main springs 7, and on the lower connecting plate 3, a load-reducing spring 5 is provided on the outer side of each transition spring 6. The height of the transition spring 6 is also less than the height of the main spring 7, and the height of the load-reducing spring 5 is also less than the height of the adjacent transition spring 6. A plurality of cylindrical pins 12 are also provided at both ends of the lower connecting plate 3. The cylindrical pins 12 at the ends of the lower connecting plate 3 pass through the ends of the lower connecting plate 3 and fix the corresponding unloading springs 5, transition springs 6 and main springs 7 provided on the lower connecting plate 3. The main springs 7, transition springs 6 and unloading springs 5 ​​provided on the upper connecting plate 4 and the lower connecting plate 3 are all made of spring steel with elasticity. In this embodiment, there are a total of eight groups of buffer mechanisms consisting of corresponding unloading springs 5, transition springs 6 and main springs 7.

[0019] In the embodiment of the present invention, two wedge pieces 8 are respectively arranged between two adjacent load-reducing spring pieces 5 on the upper connecting plate 4.

A plurality of cylindrical pins 12 are respectively arranged at the two ends of the upper connecting plate 4. The cylindrical pins 12 at the ends of the upper connecting plate 4 pass through the ends of the upper connecting plate 4 and fix the load-reducing spring pieces 5, transition spring pieces 6, main spring pieces 7, and wedge pieces 8 correspondingly arranged on the upper connecting plate 4, so that the possibility of the wedge pieces 8 loosening when impacted can be reliably guaranteed.

[0020] The present invention provides a plurality of connectors consisting of cylindrical head hexagon socket screws 9, washers 10 and elastic washers 11 on the upper connecting plate 4, and the products (such as optoelectronic products such as observation and aiming products) are connected to the upper connecting plate 4 through these connectors. A locking block 2 is connected to the lower connecting plate 3 through a locking nut 1, and the docking base product connection seat is connected to the lower connecting plate 3 through the locking nut 1 and the locking block 2. The present invention uses the elasticity of the main spring 7 to play a major buffering role, which can reduce the large impact acceleration generated by the docking product into a small acceleration acting on the upper connecting plate 4, so that the used product is affected by the small impact acceleration. The load-reducing spring 5 and the transition spring 6 secondarily reduce the force of the main spring 7, improve the strength reliability of the main spring 7, and thus effectively achieve the buffering of the impact of strong impact acceleration.
