2. The present invention sets the shock absorbing device as a columnar structure, and its side wall is a corrugated structure, which is more conducive to deformation when subjected to the vibration of the high-speed fan, and plays a buffering role on the vibration. At the same time, the internal air cavity can offset part of the vibration force during the extrusion process, thereby improving the shock absorption effect.

3. The present invention arranges an even number of shock absorbing devices on both the side panels and the bottom panel, which can ensure the stability of the high-speed fan during operation and prevent the high-speed fan from deviating during operation.

4. The shock absorbing device of the present invention is made of silica gel, which is soft and has good buffering effect, thereby preventing the high-speed fan from having a hard collision when rotating, and ensuring the service life of the high-speed fan.

When connecting the shock absorbing device to the bracket, the connection can be quickly installed, which saves the time of determining the connection position and improves the working efficiency.

6. The present invention configures the shock absorbing device as a structure with openings at both ends, which can save materials, reduce costs, and make processing more convenient.

7. The present invention configures the shock absorbing device as a bottom open structure, and the upper horizontal end surface is more stable when connected to the high-speed fan, which can provide a certain fixed support for the high-speed fan and increase the service life of the shock absorbing device; adding a stabilizing ring can ensure the stability of the bottom connection of the shock absorbing device, increase the contact area, and ensure a more secure connection; exhaust holes are set on the side to discharge air when squeezed to perform buffering and shock absorption, thereby avoiding deformation of the shock absorbing device due to air pressure and ensuring the shock absorption effect.

8. The present invention arranges a suction cup on the shock absorbing device. When the high-speed fan vibrates, if the high-speed fan is far away from the shock absorbing device, the shock absorbing device will not separate from the high-speed fan. Under the action of the suction cup, the shock absorbing device can hold the high-speed fan and also play a shock absorbing role on the high-speed fan, so that the shock absorbing device has a two-way shock absorbing effect, thereby improving the shock absorbing effect.

9. The present invention provides a fixing block on the bracket to fix the high-speed fan to the bracket, thereby preventing the high-speed fan from being displaced from the bracket due to vibration during use. The fixing block and the bracket can rotate, which is convenient for installation and disassembly of the high-speed fan and easy to use.
