The housing structure 2 can be installed in an electronic device for supporting a plurality of electronic components of the electronic device. As shown in FIG. 3A, the housing structure 2 comprises a main body 21 and the handler 23.

Note that in the following embodiments the housing structure 2 can be applied to housings adopted by varieties of electronic devices, such as desktop computers, notebook computers and servers. Although the following embodiment takes a rack adopted by an electronic device such as a server as an example, the present invention is not limited to be this. Moreover, since the present invention is applicable to a desktop computer, a notebook computer or any other electronic device having a drawable box, only structures directly related to the present invention are shown in the figures for clarity and simplicity.

As shown in FIG. 3A, the main body 21 further comprises a front surface 211 and a top surface 213 connected to the front surface 211. The front surface 211 comprises an opening 2111 in the shape of a rectangle. The top surface 213 comprises a first opening 2131. The front surface 211 further comprises a plurality of engaging openings 2113 for connecting to external connection devices (not shown), such as a universal serial bus (USB) electronic device or a multimedia displayer. Note that the opening 2111 can be in other shapes changed in accordance with practical demands. For example, the opening 2111 can be in the shape of a circle or an ellipse.

As shown in FIG. 4, the handler 23 comprises a cantilever 231 for engaging with the first opening 2131, and a rotatable fixing member 233 engaged with the cantilever 231 for fixing to the opening 2111. Therefore, any space consumption of the rotatable fixing member 233 if installed on the main body 21 is unneeded. The rotatable fixing member 233 comprises an installation pins 2335 for installation of an elastic member 235, which is a winding leaf spring for propping against a propping region between the rotatable fixing member 233 and the cantilever 231 to strengthen the tightness of the rotatable fixing member 233 and the opening 2111. According to the preferred embodiment, the elastic member 235 is a linear spring, a metal spring, a leaf steel, a spring slice or any other equivalent structure. The cantilever 231 of the handler 23 comprises a second opening 2311, a third opening 2313 and a propping portion 2319. The cantilever 231 fixes the handler 23 to the main body 21 by passing a screw bolt (not shown) through the second opening 2311 and the first opening 2131 of the top surface 213 of the main body 21. The rotatable fixing member 233 comprises a top cover 2331 and a bottom cover 2333. The top cover 2331 comprises a hooking portion 2331a, a ring-shaped body 2331b and a first engaging portion 2331c.
