The rotating shaft of the motor 22 is a driving shaft 21.

An arm-shaped decorative arm shell 6 is fixed on a pulling part of the pulling switch 24, a loop between the motor 22 and the rechargeable battery 23 is switched on by pushing the decorative arm shell 6 upwards, and the motor 22 drives the folding fan blade assembly 3 to rotate to achieve the aim of blowing.

Preferably, when the rotary housing 4 rotates to make the opening 41 completely expose the folding fan blade assembly 3, a notch for the decorative arm shell 6 to extend into is formed on the rotary housing 4 corresponding to the position above the decorative arm shell 6. When the decorative arm shell 6 is aligned with the notch, the decorative arm shell 6 can be pushed up to drive the toggle switch 24 to switch on the loop between the motor 22 and the rechargeable battery 23, and the motor 22 works. When the rotary shell 4 is not screwed to a preset position, namely the opening 41 can not completely expose the folding fan blade assembly 3, the positions of the decorative arm shell 6 and the notch are staggered, the decorative arm shell 6 can not be pushed upwards, the problem that the motor is burnt out due to the fact that a motor loop is switched on by misoperation is solved, the service life is effectively prolonged, and the use safety is ensured.

In order to improve the placing stability, the lower end of the handle 1 is movably provided with a supporting leg 7. Specifically, the supporting leg 7 is movably arranged at the lower end of the handle 1 through a rotary connector. Specifically, inclined planes are arranged on two sides of the lower end of the handle 1, clamping holes matched with the rotary connector are arranged on the inclined planes, and the clamping holes are in interference fit with the rotary connector. When needing to place, promote landing leg 7 hard, landing leg 7 can with swivelling joint head rotates for the axial lead makes landing leg 7 with the contained angle between handle 1 is 30 ~ 90 degrees, preferably 90 degrees, and support stability is good. When the handle needs to be held or carried, the supporting legs 7 are pushed back, and the supporting legs 7 can rotate by taking the rotary connector as an axis, so that an included angle between the supporting legs 7 and the handle 1 is 180 degrees. Can prolong the length of the handle 1 to facilitate holding, and avoid the protrusion of the supporting legs 7, thereby facilitating carrying.

Embodiment 2, referring to fig. 5 to 7, the portable fan provided in this embodiment adopts a manual driving manner, and the structure of the portable fan is substantially the same as that of the embodiment, except that the blade driving device 2 is a manual driving device. Manual drive device includes dead lever 26, drive tooth 27, moves about tooth 28, driving tooth 29, output tooth 210 and extension spring 211, the upper portion of dead lever 26 articulates in head shell 5, and be equipped with the fan-shaped tooth that drives tooth 27 and mesh mutually, the one end of extension spring 211 is connected in this fan-shaped tooth one side, and the other end of this extension spring 211 is connected in head shell 5, output tooth 210 passes through drive shaft 21 and sets up on head shell 5, driving tooth 29 with output tooth 210 meshes mutually, be equipped with a confession in head shell 5 when moving tooth 28 and moving to the high position simultaneously with driving tooth 29 and drive tooth 27 mesh mutually, and move when low level with the arc of driving tooth 29 phase separation is moved the groove.

Referring to fig. 7, when the lever 26 is pressed and the sector gear drives the driving gear 27 to rotate clockwise, the movable gear 28 is automatically pushed to move upwards to the high position of the arc-shaped slot, so as to simultaneously mesh with the transmission gear 29 and the driving gear 27.
