[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 A portable clamp fan includes a clamp fan body 1, a first support rod 2 at the lower end of the clamp fan body 1, a second support rod 3 at the lower end of the first support rod 2, a horizontal clamping unit at the lower end of the second support rod 3, and a base 4 at the lower end of the horizontal clamping unit. The horizontal clamping unit includes a first horizontal clamping block and a second horizontal clamping block. The first horizontal clamping block includes a first connecting part 5, a first clamping part 6, and a first operating part 7. The lower surface of the first connecting part 5 is an upwardly convex arc shape. Two first protrusions 8 are provided at the lower end of the connection between the first connecting part 5 and the first operating part 7. The lower surface of the first clamping part 6 is provided with a first clamping opening 9. The second horizontal clamping block includes a second connecting part 10, a first clamping part 11, a second horizontal clamping part 12, a first horizontal clamping part 13, a second horizontal clamping part 14, a first horizontal clamping part 15, a first horizontal clamping part 16, a first horizontal clamping part 17, a first horizontal clamping part 18, a first horizontal clamping part 19, a first horizontal clamping part 10, a first horizontal clamping part 11, a second horizontal clamping part 12, a first horizontal clamping part 13, a first ... The second clamping part 11 and the second operating part 12 have a second connecting part 10 with an upper surface that is convex downwards in an arc shape. Two second protrusions 13 are provided at the lower end of the connection between the second connecting part 10 and the second operating part 12. The upper surface of the second clamping part 11 has a second clamping jaw 14 that matches the first clamping jaw 9. The two second protrusions 13 and the two first protrusions 8 are rotatably connected via a first rotating shaft 15. The first rotating shaft 15 is fitted with two first torsion springs 16. One end of each first torsion spring 16 is connected to the first connecting part 5, and the other end is connected to the second connecting part 10. A connecting rod 17 is provided in the middle of the first rotating shaft 15, and the connecting rod 17 is connected to a longitudinal clamping unit. Because the lower surface of the first connecting part 5 is convex upwards in an arc shape and the upper surface of the second connecting part 10 is convex downwards in an arc shape, operating space can be provided for the longitudinal clamping unit.

[0021] The longitudinal clamping unit includes a first longitudinal clamping block 18, a second longitudinal clamping block 19, and a second rotating shaft 20. The first longitudinal clamping block 18 has the same structure as the first horizontal clamping block, and the second longitudinal clamping block 19 has the same structure as the second horizontal clamping block. The middle part of the second rotating shaft 20 is connected to one end of the connecting rod 17. The first longitudinal clamping block 18 and the second longitudinal clamping block 19 are rotatably connected through the second rotating shaft 20. The second rotating shaft 20 is fitted with two second torsion springs 21. One end of the two second torsion springs 21 is connected to the first longitudinal clamping block 18, and the other end of the two second torsion springs 21 is connected to the second longitudinal clamping block 19. Since the first longitudinal clamping block 18 has the same structure as the first horizontal clamping block, and the second longitudinal clamping block 19 has the same structure as the second horizontal clamping block, the arc-shaped structure in the middle of the first longitudinal clamping block 18 and the arc-shaped structure in the middle of the second longitudinal clamping block 19 can provide operating space for the horizontal clamping unit.

[0022] First rubber pads 22 are provided on the opposing surfaces of the first longitudinal clamping block 18 and the second longitudinal clamping block 19. The two first rubber pads 22 are located at the end of the longitudinal clamping unit away from the second rotating shaft 20. The first rubber pads 22 can make the first longitudinal clamping block 18 and the second longitudinal clamping block 19 clamp more firmly.

[0023] Both the first support rod 2 and the second support rod 3 have misaligned notches 23 at their opposite ends. A bolt 24 is located on the side of the second support rod 3, with one end of the bolt 24 passing through both notches 23 and threaded with a nut 25. When the object to be installed on this clamping fan is not horizontal or vertical enough, the relative positions of the first support rod 2 and the second support rod 3 can be adjusted by rotating them around the bolt 24, thereby correcting the position of the clamping fan.

[0024] The base 4 has suction cups 26 at each of its four corners on its lower surface. The suction cups 26 allow the clamp fan to be attached to a smooth surface.

[0025] A second rubber pad 27 is provided on the opposing surfaces of the first clamping part 6 and the second clamping part 11. The second rubber pad 27 can make the first clamping part 6 and the second clamping part 11 clamp more firmly.

[0026] Working principle: When the clamping fan needs to clamp a horizontal object, by pressing the first operating part 7 and the second operating part 12 with your hand, the first clamping part 6 and the second clamping part 11 can be separated by the hinge of the first rotating shaft 15. Due to the elastic force of the first torsion spring 16, the horizontal object can be clamped. The first clamping opening 9 and the second clamping opening 14 can clamp rod-shaped horizontal objects. When the clamping fan needs to clamp a vertical object, by pressing the tail of the first vertical clamping block 18 and the second vertical clamping block 19 with your hand, the heads of the first vertical clamping block 18 and the second vertical clamping block 19 can be separated by the hinge of the second rotating shaft 20. Due to the elastic force of the second torsion spring 21, the vertical object can be clamped. The clamping openings in the first vertical clamping block 18 and the second vertical clamping block 19 can clamp rod-shaped vertical objects. The base 4 allows the clamping fan to be placed on a table.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
