By using a base and a telescopic support rod 8 that are detachably connected, the telescopic support rod 8 can be detached from the base when storage is required, thereby reducing the storage space.

[0028] The base includes a bottom sleeve 2 and a plurality of support feet 1. The bottom surface of the bottom sleeve 2 contacts the ground. Sleeve 3 corresponding to the support feet 1 one by one is provided on the outer peripheral surface of the bottom sleeve 2. A card slot 4 is provided on the sleeve 3. One end of the support foot 1 is a support end that contacts the ground, and the bottom surface of the bottom sleeve 2 contacts the ground, playing a supporting role for the present application. The support end of the support foot 1 contacts the ground, playing a supporting role for the present application. Good support performance is achieved and the stability is better.

[0029] The other end of the support foot 1 is a connection end provided with a card strip 5. A reverse buckle 6 corresponding to the card slot 4 is provided on the card strip 5. When the connection end of the support foot 1 is inserted into the sleeve 3, the reverse buckle 6 is embedded into the card slot 4. When the card strip 5 is subjected to a downward external force, it deforms and drives the reverse buckle 6 out of the card slot 4. During assembly, only the connection end of the support foot 1 needs to be inserted into the sleeve 3. At this time, the reverse buckle 6 is embedded into the card slot 4 to realize the locking of the support foot 1 and the bottom sleeve 2. When disassembly and storage are required, the user only needs to press down the card strip 5 to realize the reverse buckle 6 coming out of the card slot 4. The structural design of the present application facilitates the assembly and disassembly of the user, giving the user a better experience.

[0030] Embodiment 2, as Figures 1 to 4 shown, a threaded hole is provided along the central axis of the bottom sleeve 2, and an external thread is provided at the bottom of the telescopic support rod 8. The telescopic support rod 8 is threadedly connected to the bottom sleeve 2. It is the preferred connection structure of the present application.

[0031] A retaining ring 7 is provided on the telescopic support rod 8. When the telescopic support rod 8 is screwed onto the bottom sleeve 2 in place, the retaining ring 7 blocks against the bottom sleeve 2. In this application, the provision of the retaining ring 7 effectively prevents the telescopic support rod 8 from being over-connected to the bottom sleeve 2.

[0032] The telescopic support rod 8 includes an upper support rod and a lower support rod connected by a locking member. The lower support rod is sleeved outside the upper support rod. In the unlocked state of the locking member, the upper support rod can move up and down along the axial direction relative to the lower support rod. In this application, the adjustable height of the fan is achieved through the telescopic support rod 8.

[0033] The other content of the second embodiment is the same as that of the first embodiment.

[0034] Embodiment 3, as Figures 1 to 4 shown, the longitudinal section of the sleeve 3 has a rectangular frame structure, and the support leg 1 is integrally in the shape of a rectangular rod. In this application, the sleeve 3 with a rectangular cross-section cooperates with the support leg 1, enabling the stable installation of the support leg 1 and preventing the support leg 1 from shaking within the sleeve 3.

[0035] The card slot 4 is opened on the lower bottom surface of the bottom sleeve 2. The support leg 1 is a hollow structure with an open bottom surface, and the card strip 5 is provided at the bottom of the support leg 1 and is located inside the support leg 1. In this application, the design of the open bottom surface of the support leg 1 effectively reduces the contact area between the bottom surface of the support leg 1 and the ground surface, thereby improving the accuracy of the surface where the support surface is located. Then, in this application, the card strip 5 is provided at the bottom of the support leg 1 and is located inside the support leg 1, which can prevent the external environment during the operation of the fan from accidentally touching the card strip 5.

[0036] The card strip 5 is arranged along the length direction of the support leg 1. The bottom surface of the card strip 5 is provided with an inverted buckle 6 and a number of protrusions 9. The bottom of the inverted buckle 6 protrudes from the support leg 1, and the protrusions 9 are arranged at the ends of the protrusion strip. The end of the card strip 5 extends outside the sleeve 3. In this application, the provision of the protrusion 9 structure on the card strip 5, on the one hand, improves the structural strength of the card strip 5, and on the other hand, increases the friction at the end of the card strip 5, enabling the user to apply force to press down the card strip 5.

[0037] The bottom surface of the bottom sleeve 2 has two coaxial circular ring structures. The sleeve 3 is arranged higher than the bottom surface of the bottom sleeve 2, and the inverted buckle 6 is arranged higher than the bottom surface of the bottom sleeve 2. That is, the structure of the sleeve 3 is elevated and will not contact the ground, thereby avoiding the influence of the ground environment on the structures of the sleeve 3 and the inverted buckle 6 and ensuring the reliability after their installation.

[0038] Interleaved reinforcing sheets 10 are arranged inside the support leg 1. With the above structural arrangement, while saving material costs, the support leg 1 has sufficient structural strength.

[0039] The described base includes four feet 1, and four sleeves 3 are correspondingly arranged on the outer peripheral surface of the bottom sleeve 2, and the four sleeves 3 are arranged in a cross structure. This is the preferred structural design of this application.
