Title: Electronic device

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to an electronic device. 
     2. Description of Related Art 
     The combination of a screw and a nut cooperatively forming a fastening structure to fasten a component member is widely used. For example, when an assembly member is fasten to an electronic device with a plastic housing by the above fastening structure, the nut is commonly secured to a plastic post of the housing by hot melting. However, the hot melting method is costly. Further, when the hot melting temperature is not high enough to make the post melt, the post does not form properly and it is difficult to secure the nut to the housing. 
     Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
     Referring to  FIGS. 1-3 , the electronic device  100  includes a first housing  10 , a second housing  20 , a component member  30 , and a rotating mechanism  40 . The first housing  10  combines the second housing  20  to form a receiving space. The component member  30  is received between the first housing  10  and the second housing  20 , and secured on the first housing  10  via a plurality of screws  50 . The rotating mechanism  40  is secured to the component member  30 , and the rotating mechanism  40  passes through the second housing  20 . 
     The screw  50  includes a disk-like head  51  and a columnar shaft  51  connected to the head  51 . 
     The component member  30  is made of metal and is substantially a rectangular board. A plurality of first through holes  31  are defined in the component member  30 . In the embodiment, the number of the first through holes  31  is four. The first through holes  31  are defined in four predetermined positions of the component member  30 . The diameters of first through holes  31  are smaller than the diameters of the shafts  52 . 
     The rotating mechanism  40  is secured to the middle of the component member  30 , to rotatably connect to an object (not shown). 
     Four receiving posts  12  protrude from the first housing  10  and face the second housing  20 . Each post  12  corresponds with each of the first through holes  31 . Four second through holes  11  are defined to pass through the first housing  10  and each of the post  12 . Each second through hole  11  includes a first portion  110  (see  FIG. 5 ), and a second portion  111  (see  FIG. 5 ). The first portion  110  is matched to the head  51 . The second portion  111  is matched to the shaft  52 . 
     Four gathering posts  21  protrude from the second housing  20  and face the first housing  10 . Each gathering post  21  defines a gathering groove  210  (see  FIG. 5 ). Each gathering groove  210  is concentric with each of the first through holes  31 . 
     Referring to  FIGS. 4-5 , to secure the component member  30  to the first housing  10  is described as below. First, the shaft  52  of each screw  50  is passed through the receiving groove  11 . Second, the first housing  10  is placed in a plane, the component  30  is placed in the first housing  10 , the shaft  52  contacts the component member  30 , and the shaft  52  is concentric with the through hole  31 ; the second housing  20  is covered on the first housing  10 , and the gathering groove  210  is concentric with shaft  52  and the through hole  31  through hole  11 . Third, the screw  50  is screwed in the component member  30  by a screw tool (not shown), and the shaft  52  passes through the assembly member  30  to locate in the gathering groove  210 . When the screw  50  is being screwed into the component member  30 , filings may fall from the component member  30 , and the filings are gathered in the gathering groove  210  that electronic device  100  is protected against filings. At this time, the assembly member  30  is secured to the first housing  10 . 
     Even though relevant information and the advantages of the present embodiments have been set forth in the foregoing description, together with details of the functions of the present embodiments, the disclosure is illustrative only; and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
