[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4, a kind of adjustable clamping fan, including fan body 1, hinged seat 2 and clamping assembly, the clamping assembly includes top plate 3, side plate 4, bottom plate 5, screw 6, handle 7, bearing 8, lifting frame 9 and guide rod 10, the top plate 3 and bottom plate 5 are symmetrically provided on the upper and lower sides of the side plate 4, the hinged seat 2 is also provided on the top plate 3, the screw 6 penetrates the top plate 3 and is connected with the inner ring of bearing 8, the outer ring of bearing 8 is embedded on the lifting frame 9, the guide rod 10 that penetrates the top plate 3 is also provided on the lifting frame 9, the fan body 1 is hinged below the hinged seat 2.

[0024] The entire clamping assembly is vertically supported by the side plate 4, and the top plate 3 and the bottom plate 5 are located on the upper and lower sides respectively. The screw 6 penetrates the top plate 3, and the screw 6 is connected with the inner ring of the bearing 8 embedded in the lifting frame 9. At the same time, the lifting frame 9 is also provided with the guide rod 10 penetrating the top plate 3. When the operator holds the handle 7 and rotates, the screw 6 begins to rotate. Due to the principle of screw transmission, under the limiting constraint of the guide rod 10, the lifting frame 9 can only make linear lifting motion along the guide rod 10. This mechanism allows users to flexibly raise or lower the lifting frame 9 according to the actual size of the clamped object, such as the thickness of the dormitory bed body rail, to accurately adapt to objects of different diameters, and to overcome the limitations of fixed height and fixed angle of traditional clamps;

[0025] In this embodiment, a first magnetic suction groove is provided below the lifting frame 9, and a first magnetic suction seat 11 is also provided below the lifting frame 9 and magnetically attracted to the first magnetic suction groove. A first friction pad 12 is also provided below the first magnetic suction seat 11. By utilizing the characteristics of magnetic attraction, the shape combination of the lower contact component can be adjusted quickly and conveniently. Moreover, the first friction pad 12 below the first magnetic suction seat 11 can increase the friction force with the upper surface of the clamped object, making the contact more closely and improving the stability of clamping. A magnetic

[0026] The magnetic suction frame 13 is further provided with a second magnetic suction groove, and is further provided with a second magnetic suction seat 14, which is in magnetic suction connection with the second magnetic suction groove. The second magnetic suction seat 14 is further provided with a second friction pad 15. The second magnetic suction seat 14 and the second magnetic suction groove are in magnetic suction connection with each other. Such a structure can flexibly change the clamping surface as needed and match supports of different shapes. The second friction pad 15 on the second magnetic suction seat 14 further strengthens the friction force on the lower surface of the clamped object, and the upper and lower parts are matched to tightly clamp the object. For example, when the first friction pad 12 and the second friction pad 15 are both arc-shaped structures, the first friction pad 12 and the second friction pad 15 can cooperate with the arc-shaped structures to ensure that the equipment is stably fixed on the arc-shaped support when the lifting frame 9 moves downward.

[0027] In the embodiment, the bottom plate 5 is further provided with a third friction pad 16 on the left and right sides below the bottom plate 5, which prevents the whole clamped fan from sliding and moving in the left and right directions and stably connects the clamped fan and the clamped object in all directions.

[0028] In actual use, the fan body 1 adopts a conventional fan with a hinged support on the market. The back side of the fan is provided with a circuit board and a battery. In the embodiment, the hinged seat 2 is rotationally connected with the fan body 1 below. The hinged seat 2 is further provided with a pre-positioning assembly, which includes an auxiliary plate 17, an elastic member 18 and a hemispherical body 19. The hinged seat 2 is provided with the auxiliary plate 17 on one side. The elastic member 18 is connected with the auxiliary plate 17 and the hemispherical body 19 at the upper and lower ends. The top plate 3 is further provided with a plurality of grooves matched with the hemispherical body 19. When the hinged seat 2 is not subjected to external force, the corresponding angle on the top plate 3 can be adjusted and stopped. At this time, the elastic member 18 drives the hemispherical body 19 to extend into the groove under the support of the auxiliary plate 17. The elastic member 18 includes a spring and a telescopic rod to ensure the stability of the movement of the hemispherical body 19. The hinged seat 2 and the top plate 3 are connected by damping.
