A connecting opening 321 is provided at the top of the push plate 32, and a connecting groove 311 is provided at the top of the guide plate 31. The connecting opening 321 is correspondingly arranged with the connecting groove 311. A limiting column 35 is movably connected between the connecting opening 321 and the connecting groove 311. The connecting groove 311 is provided with a plurality of groups. The fan body 1 is placed At the top of the support plate 2, the push plate 32 is pushed to slide along the guide plate 31 so that the fixed plate 34 contacts the outer surface of the fan body 1. After the movement is completed, the limit column 35 is connected to the connecting groove 311 through the connecting port 321 to fix the push plate 32 to the top of the guide plate 31, thereby fixing the fan body 1 to the top of the support plate 2. The design of the sliding connection between the guide plate 31 and the push plate 32 facilitates the fixation of fan bodies 1 of different sizes and models, thereby increasing the versatility of the fixing component 3, and has a simple structure, does not require a driving device, and has a low manufacturing cost.

[0026] The fixing plate 34 and the connecting column 33 are both made of a rubber material. Rubber is a natural elastic material that facilitates fine-tuning when installing the fan body 1. When the fan body 1 vibrates, the fixing plate 34 and the connecting column 33 facilitate buffering and reducing the transmission of vibration.

[0027] A groove 41 is provided on one side of the supporting leg 4, a sliding rod 6 is fixedly connected inside the groove 41, a connecting block 5 is slidably connected to the outer surface of the sliding rod 6, a first shock-absorbing spring 51 is fixedly connected between the connecting block 5 and the top end of the inner wall of the groove 41, a second shock-absorbing spring 52 is fixedly connected between the connecting block 5 and the bottom end of the inner wall of the groove 41, and the connecting block 5 is fixedly connected to the supporting plate 2. When the fan body 1 vibrates during operation, the first shock-absorbing spring 51 and the second shock-absorbing spring 52 form a double shock-absorbing mechanism, which is convenient for effectively absorbing the vibration energy generated by the fan body 1 during operation from the upper and lower directions, and at the same time, it is convenient to automatically adjust the compression amount according to the actual vibration frequency and intensity of the fan body 1 during operation, so as to always maintain the best shock-absorbing effect.

[0031] When in use, place the fan body 1 on the top of the support plate 2, push the push plate 32 to slide along the guide plate 31, so that the fixed plate 34 contacts the outer surface of the fan body 1, and after the movement is completed, the limit column 35 is connected to the connecting groove 311 through the connecting port 321, and the push plate 32 is fixed to the top of the guide plate 31, so that the fan body 1 is fixed to the top of the support plate 2. The design of the sliding connection between the guide plate 31 and the push plate 32 makes it easy to fix the fan bodies 1 of different sizes and models. When the fan body 1 is running, the fixed plate 34 and the connecting column 33 are convenient for buffering and reducing vibration The first shock-absorbing spring 51 and the second shock-absorbing spring 52 form a double shock-absorbing mechanism, which is convenient for effectively absorbing the vibration energy generated by the operation of the fan body 1 from the upper and lower directions. The third shock-absorbing spring 82 and the fourth shock-absorbing spring 83 further enhance the shock-absorbing effect, effectively cope with lateral vibration, and reduce the transmission of vibration to the foundation and the surrounding environment. Through the joint action of the first shock-absorbing spring 51, the second shock-absorbing spring 52, the third shock-absorbing spring 82 and the fourth shock-absorbing spring 83, it is convenient to absorb and disperse vibration from multiple directions to improve the stability of the operation of the fan body 1.
