Fan mounting structure

Abstract

A fan mounting structure includes a casing, a fixing support and a protection means. The outside of the casing has an opening. The fixing support is connected to the casing and is provided with a fan accommodating space. The fan accommodating space is in communication with the opening. The protection means is connected to the casing. Via this arrangement, after the user detaches the fan body from the fixing support, the protection means can protect the electronic components within the casing from suffering damage due to external forces.
