By providing the clamping plate 220 on the outer surface of the handle 210 on one side of the air outlet, it is ensured that the air blown out from the fan body is directed towards the user himself without adjusting the angle of the fan body in the original state.

[0032] In addition, a plurality of strap holes 215 for connecting the strap may be provided on the handle 210.

[0032] The technical features of the above embodiments can be arbitrarily combined. For the sake of brevity of description It does not describe all possible combinations of the technical features of the above embodiments. However, as long as there is no contradiction in the combination of these technical features, it should be regarded as within the scope described in this specification.
