The support plate 22 is provided with a fixing groove 25 that is plugged and matched with the second elastic member 34.

[0027] Specific application examples of the utility model:

[0028] The fan body 1 is arranged on the support plate 22 in the support seat 2. The longitudinal vibration generated by the fan body 1 during operation is buffered and absorbed by the shock absorbing assembly 3 arranged between the support plate 22 and the base 21, thereby reducing the amplitude generated during the operation of the fan body 1. The buffer assembly can be made of a shock absorbing spring. One end of multiple groups of buffer assemblies is hingedly connected to the base 21, and the unused buffer assembly is arranged horizontally with the base 21 in the base 21. When the buffer assembly is used, the buffer assembly is rotated so that the buffer assembly is away from the hinged end of the base 21 and is connected and fixed to the lower wall of the support plate 22. The two ends of the buffer assembly are respectively connected to the base 21 and the support plate 22. At this time, the buffer assembly absorbs the force of the longitudinal movement to achieve the purpose of shock absorption. Multiple groups of buffer assemblies can be replaced and used in sequence.

[0029] The buffer assembly is provided with a connecting block 31 hingedly connected to the base 21 at one end thereof near the base 21. The first elastic member 32 may be made of a material having elastic deformation. The first elastic member 32 and the plurality of positioning grooves 23 provided in the base 21 are plugged and matched with each other to limit the relative position of the shock absorbing assembly 3 and the base 21. It is ensured that when the shock absorbing assembly 3 is connected to the support plate 22, the shock absorbing assembly and the base 21 remain perpendicular to each other. The first telescopic assembly 24 may be made of an electric telescopic rod. The first telescopic assembly 24 is arranged vertically to the base 21, and the extended free end of the first telescopic assembly 24 abuts against the lower side of the connecting block 31. When the shock absorbing assembly 3 is connected to the support plate 22, the first telescopic assembly 24 abuts against the connecting block 31 to support the connecting block 31 and the shock absorbing assembly 3, so as to prevent the weight of the fan body 1 on the support plate 22 from being transmitted to the connecting block 31, resulting in the bending of the connecting shaft between the connecting block 31 and the base 21. The second telescopic assembly 51 may be made of an electric telescopic rod. The second telescopic assembly 51 drives the clamping plate 5 to move, and the two groups of clamping plates 5 are oppositely located on both sides of the connecting block 31, and the connecting block 31 is fixed by clamping the clamping plates 5. The fixing block 33 and the support plate 22 are detachably connected to each other and can be fixed by bolts. The second elastic member 34 can be made of a material with elastic deformation. The second elastic member 34 matches the fixing groove 25 provided on the support plate 22 to position the relative position of the fixing block 33 and the support plate 22.

[0030] The column 4 is arranged between the support plate 22 and the base 21. The inner sleeve rod 41 of the column 4 and the slide rod 42 are slidably connected to each other, so as to limit the vibration path of the support plate 22 and ensure that the support plate 22 vibrates vertically to avoid tilting. The third telescopic assembly 43 can be made of an electric telescopic rod. The third telescopic assembly 43 and the slide rod 42 abut against each other. When the shock absorbing assembly 3 is replaced, the third telescopic assembly 43 and the slide rod 42 are used to support and fix the support plate 22.
