[0028] Example:

[0029] Please see Figure 1 - Figure 5 A foldable handheld fan includes a fan body 1, a base column 2 fixedly connected to the lower end of the fan body 1, a positioning block 3 fixedly connected to the lower end of the base column 2, a rotating groove on both ends of the positioning block 3, a rotating shaft 6 rotatably connected in the rotating groove, a folding half column 4 fixedly connected on the rotating shaft 6, and a storage groove matching the folding half column 4 on both ends of the base column 2.

[0030] The folding half-column 4 includes a main body 41, a rotating part 42, and a magnetic block 43. The rotating part 42 is fixedly connected to the rotating shaft 6, and the main body 41 is fixedly connected to the outer end of the rotating part 42. The magnetic block 43 is embedded in the outer end of the main body 41. The connection between the rotating part 42 and the rotating shaft 6 provides space for the main body 41 to rotate. The main body 41 has three folding modes. The first mode is to rotate upwards into the storage slot to achieve the overall folding of the fan, reducing space occupation and making it easy to carry. The second mode is to place it parallel to the base column 2. At this time, the main body 41 is at a right angle to the base column 2 and can be placed on a flat surface to serve as a base without needing to hold it. The magnetic block 43 not only acts as a counterweight to ensure the stability of the base and prevent it from tipping over, but also has its own magnetism to attract each other to ensure stability when stored. Secondly, it can also be attracted to a vertical plane, as long as the vertical plane has magnetism. The last mode is to rotate downwards to keep it in a straight line with the base column 2, making it easy to hold after unfolding.

[0031] The positioning block 3 has two sets of through holes that match the rotating shaft 6. A rotating column 7 is rotatably connected in the through holes and extends to the outside of the positioning block 3. The rotating column 7 is fixedly connected to the rotating shaft 6. The user can rotate the rotating column 7 to drive the rotating shaft 6 to rotate, thereby driving the folding half column 4 to various folding modes, which is convenient and easy to operate.

[0032] An anti-slip sleeve 5 is fixedly connected to the outer end of the rotating column 7. The anti-slip sleeve 5 has anti-slip texture, which allows the user to rotate the column more easily and prevents it from slipping.

[0033] The rotating column 7 has multiple evenly distributed hidden slots. A matching locking ball 8 is provided at the opening of the hidden slot. A compression spring 9 is fixedly connected between the locking ball 8 and the bottom wall of the hidden slot. A number of matching extrusion slots are provided on the inner side wall of the through hole. When the rotating column 7 rotates, the locking ball 8 is extruded and enters the hidden slot to facilitate rotation. When it rotates to the extrusion slot, it is locked in by the elastic force of the compression spring 9 to achieve temporary positioning after rotation and ensure stability after folding.

[0034] The number of the hidden slots is four, and the angle between adjacent slots is 90 degrees, and the extrusion slot is an arc slot, since the three folding modes of the folding half column 4 are 0 degrees, 90 degrees and -90 degrees, the number of the slots is set to four, and positioning can be realized after each rotation of 90 degrees.

[0035] Working principle: storage mode, in this mode, the main body 41 is in the storage slot, the overall occupied area is reduced for easy carrying, placement mode, in this mode, the main body 41 is rotated by 90 degrees to be perpendicular to the base column 2, at this time, it can be placed on a plane to serve as a base, the user can use the fan without holding, handheld mode, in this mode, the main body 41 is continuously rotated by 90 degrees to be in line with the base column 2, then the user can use by holding a pair of main bodies 41, in addition, in a non-planar state or a narrow use space, a certain gap is left between a pair of main bodies 41, which can be clamped into a placement position for hanging use.

[0036] The above is only the preferred embodiment of the present application; however, the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the improvement concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
