[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Secondly, the term "one embodiment" or "example" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearance of an embodiment in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0017] Example Reference Figures 1-4 This is an embodiment of the present invention, which provides a dual-purpose (tabletop and floor) fan, comprising: The main body 100 includes a first drive motor 101, a transmission shaft 102 adapted to be installed at the output end of the first drive motor 101, a fan blade 103 fixedly connected to the end of the transmission shaft 102, and a protective cover 104 sleeved on the surface of the fan blade 103. The adjustment mechanism 200 includes a connecting block 201 disposed at the bottom of the first drive motor 101, a telescopic component 203 fixedly connected to the bottom of the connecting block 201, an operation panel 204 welded to the side wall of the telescopic component 203, and a fixing component 205 fixedly connected to the bottom of the telescopic component 203; the main body mechanism 100 also includes a connecting column 105 fixedly connected to the bottom of the first drive motor 101, and the connecting column 105 is fixedly connected to the connecting block 201. The fixing component 205 includes a threaded rod 205a fixedly connected to the bottom of the telescopic component 203, a bearing plate 205b welded to the bottom of the threaded rod 205a, an auxiliary fixing plate 205c disposed on the surface of the threaded rod 205a, and a fixing sleeve 205d rotatably connected to the surface of the threaded rod 205a. The threaded rod 205a is used in conjunction with the auxiliary fixing plate 205c and the fixing sleeve 205d. The outer diameter of the threaded rod 205a is the same as the inner diameter of the auxiliary fixing plate 205c and the inner diameter of the fixing sleeve 205d, and the fixing sleeve 205d is located on top of the auxiliary fixing plate 205c.

[0018] Specifically, the fixing component 205 constructs a stable support base through the welding structure of the threaded rod 205a and the bearing plate 205b, ensuring the vertical stability of the overall device; the tight fit between the auxiliary fixing plate 205c and the threaded rod 205a, combined with the screw-locking of the fixing sleeve 205d, forms a double fastening structure, which not only enhances the adaptability to different mounting surfaces, but also allows for fine adjustment of the support height by screwing the fixing sleeve 205d, compensating for unevenness of the mounting surface; the precise matching of the inner diameter of the three components with the outer diameter of the threaded rod 205a eliminates connection gaps, effectively disperses the vibration load generated during equipment operation, and prevents the risk of loosening.

[0019] Furthermore, the main body 100 also includes a connecting column 105 fixedly connected to the bottom of the first drive motor 101, and the connecting column 105 is fixedly connected to the connecting block 201; the adjustment mechanism 200 also includes a connecting groove 202 opened on the top of the connecting block 201, and the connecting groove 202 is used in conjunction with the connecting column 105, and the inner diameter of the connecting groove 202 is the same as the outer diameter of the connecting column 105.

[0020] Preferably, in the main body 100, the first drive motor 101 drives the transmission shaft 102 to drive the fan blade 103 to operate efficiently, and the protective cover 104 ensures safe use; the adjustment mechanism 200 achieves height adjustment through the connection of the connecting block 201 and the connecting column 105, and works with the telescopic component 203; the fixing component 205 enhances the overall stability.

[0021] It should be noted that the telescopic assembly 203 includes a telescopic sleeve rod 203d fixedly connected to the bottom of the connecting block 201, a lead screw 203c rotatably connected to the inner wall of the telescopic sleeve rod 203d, and a housing 203a sleeved on the surface of the telescopic sleeve rod 203d; the telescopic assembly 203 also includes a second drive motor 203b fixedly connected to the bottom of the inner cavity of the housing 203a, and the second drive motor 203b cooperates with the lead screw 203c, and the end of the lead screw 203c is adapted to be installed at the output end of the second drive motor 203b.

[0022] In the telescopic assembly 203, the second drive motor 203b drives the lead screw 203c to mesh with the telescopic sleeve 203d for transmission, and works in conjunction with the outer shell 203a for guide and limit, to achieve smooth height adjustment, ensuring both adjustment accuracy and improving load-bearing stability.

[0023] In use, the first drive motor 101 of the main body 100 drives the transmission shaft 102 to rotate the fan blades 103 and generate wind power, while the protective cover 104 ensures safe use. The connecting block 201 of the adjustment mechanism 200 is tightly connected to the connecting column 105 of the main body 100 through the top connecting groove 202 to achieve a stable connection. The second drive motor 203b of the telescopic component 203 drives the lead screw 203c to rotate, which drives the telescopic sleeve 203d to rise and fall along the inner wall of the outer shell 203a to achieve height adjustment of the fan blades 103. The operation panel 204 can control the operation of the motor. The threaded rod 205a of the fixing component 205 is fixed to the outer shell 203a, the bearing plate 205b provides stable support, and the auxiliary fixing plate 205c is tightened and locked on the threaded rod 205a through the fixing sleeve 205d, which can adapt to different installation requirements on the table or the ground.

[0024] In summary, in the main structure 100, the protective cover 104 ensures safe use, and the stable connection between the connecting column 105 and the connecting block 201 enhances the overall structural strength; the connecting groove 202 of the adjustment mechanism 200 is precisely matched with the connecting column 105, improving assembly stability; the telescopic component 203 uses a combination of a lead screw 203c and a second drive motor 203b, which can flexibly adjust the fan height to meet the needs of switching between tabletop and floor use scenarios, and is easy to operate; the fixing component 205, through the cooperation of the threaded rod 205a, the auxiliary fixing plate 205c and the fixing sleeve 205d, can stably fix the fan to the desktop or the ground to prevent it from tipping over.
