[0029] Referring to the drawings Figures 1-5An adjustable handheld fan, as described in this embodiment, includes a handle 1, a mounting frame 2, a fan body 3, and a connecting assembly 6. The mounting frame 2 is snapped onto the handle 1, and a lanyard 21 is connected to the outer side of the mounting frame 2. The fan body 3 includes a housing 4, which has an air outlet 5. The fan body 3 is rotatably mounted relative to the mounting frame 2. The connecting assembly 6 is disposed between the fan body 3 and the mounting frame 2. The connecting assembly 6 includes an opening 7, a rotating shaft 8, and a positioning member 9. The opening 7 allows the rotating shaft 8 to pass through and is relatively movable. The positioning member 9 includes a first positioning protrusion 10 and a second positioning protrusion 11, which are arranged circumferentially along the rotating shaft 8. The rotating shaft 8 has a radial protrusion 12 that cooperates with the positioning member 9. The opening 7 is located on the housing 4, and the rotating shaft 8 is located on the mounting frame 2. The rotating shaft 8 has... A circumferential convex ring 13 is provided. An inner shell 14 is installed inside the outer shell 4. The circumferential convex ring 13 is located between the outer shell 4 and the inner shell 14. A radial protrusion 12 is provided on the circumferential convex ring 13. A positioning member 9 is provided on the outer shell 4. The positioning member 9 and the air outlet 5 are located on the same side of the rotating shaft 8. There are two sets of connecting components 6. A motor is provided inside the fan body 3. The motor is connected to a fan blade 15. A battery 16 and a circuit board 17 are provided inside the grip 1. The circuit board 17 is controlled to the battery 16. The battery 16 is electrically connected to the motor. A control button 18 and a charging port are provided on the grip 1. The control button 18 is electrically connected to the circuit board 17. The charging port is electrically connected to the battery 16.
